Abstract
The gut microbiome affects the health status of the host through complex interactions with the host's intestinal wall. These host-microbiome interactions may spatially vary along the physical and chemical environment of the intestine, but these changes remain unknown. This study investigated these intricate relationships through a gene co-expression network analysis based on dual transcriptome profiling of different intestinal sites-cecum, transverse colon, and rectum-of the primate common marmoset. We proposed a gene module extraction algorithm based on the graph theory to find tightly interacting gene modules of the host and the microbiome from a vast co-expression network. The 27 gene modules identified by this method, which include both host and microbiome genes, not only produced results consistent with previous studies regarding the host-microbiome relationships, but also provided new insights into microbiome genes acting as potential mediators in host-microbiome interplays. Specifically, we discovered associations between the host gene FBP1, a cancer marker, and polysaccharide degradation-related genes (pfkA and fucI) coded by Bacteroides vulgatus, as well as relationships between host B cell-specific genes (CD19, CD22, CD79B, and PTPN6) and a tryptophan synthesis gene (trpB) coded by Parabacteroides distasonis. Furthermore, our proposed module extraction algorithm surpassed existing approaches by successfully defining more functionally related gene modules, providing insights for understanding the complex relationship between the host and the microbiome.IMPORTANCEWe unveiled the intricate dynamics of the host-microbiome interactions along the colon by identifying closely interacting gene modules from a vast gene co-expression network, constructed based on simultaneous profiling of both host and microbiome transcriptomes. Our proposed gene module extraction algorithm, designed to interpret inter-species interactions, enabled the identification of functionally related gene modules encompassing both host and microbiome genes, which was challenging with conventional modularity maximization algorithms. Through these identified gene modules, we discerned previously unrecognized bacterial genes that potentially mediate in known relationships between host genes and specific bacterial species. Our findings underscore the spatial variations in host-microbiome interactions along the colon, rather than displaying a uniform pattern throughout the colon.

Abstract
Oral health plays a significant role in the quality of life and overall well-being of the aging population. However, age-related changes in oral health are not well understood due to challenges with current animal models. In this study, we analyzed the oral health and microbiota of a short-lived non-human primate (i.e., marmoset), as a step towards establishing a surrogate for studying the changes that occur in oral health during human aging. We investigated the oral health of marmosets using cadaveric tissues in three different cohorts: young (aged ≤6 years), middle-aged, and older (>10 years) and assessed the gingival bacterial community using analyses of the V3-V4 variable region of 16S rRNA gene. The oldest cohort had a significantly higher number of dental caries, increased dental attrition/erosion, and deeper periodontal pocket depth scores. Oral microbiome analyses showed that older marmosets had a significantly greater abundance of Escherichia-Shigella and Propionibacterium, and a lower abundance of Agrobacterium/Rhizobium at the genus level. Alpha diversity of the microbiome between the three groups showed no significant differences; however, principal coordinate analysis and non-metric multidimensional scaling analysis revealed that samples from middle-aged and older marmosets were more closely clustered than the youngest cohort. In addition, linear discriminant analysis effect size (LEFSe) identified a higher abundance of Esherichia-Shigella as a potential pathogenic biomarker in older animals. Our findings confirm that changes in the oral microbiome are associated with a decline in oral health in aging marmosets. The current study suggests that the marmoset model recapitulates some of the changes in oral health associated with human aging and may provide opportunities for developing new preventive strategies or interventions which target these disease conditions.

Abstract
Common marmosets have been widely used in biomedical research for years. Nutritional control is an important factor in managing their health, and insect intake would be beneficial for that purpose because common marmosets frequently feed on insects in natural habitats. Here, we examined the effect of enhanced insect feeding on the gut by analysing the faecal microbiota and transcripts of captive marmosets. A family consisting of six marmosets was divided into two groups. During the seven-day intervention period, one group (the insect feeding group, or Group IF) was fed one cricket and one giant mealworm per marmoset per day, while the other (the control group, or Group C) was not fed these insects. RNA was extracted from faecal samples to evaluate the ecology and transcripts of the microbiota, which were then compared among time points before (Pre), immediately after (Post), and two weeks after the intervention (Follow_up) using total RNA sequencing. The gut microbiota of marmosets showed Firmicutes, Actinobacteria, Bacteroidetes, and Proteobacteria as dominant phyla. Linear discriminant analysis showed differential characteristics of microbiota with and without insect feeding treatment. Further analysis of differentially expressed genes revealed increases and decreases in Bacteroidetes and Firmicutes, respectively, corresponding to the availability of insects under both Post and Follow_up conditions. Significant changes specific to insect feeding were also detected within the transcriptome, some of which were synchronized with the fluctuations in the microbiota, suggesting a functional correlation or interaction between the two. The rapid changes in the microbiota and transcripts may be achieved by the microbiota community originally developed in the wild through marmosets' feeding ecology. The results were informative for identifying the physiological impact of insect feeding to produce a better food regimen and for detecting transcripts that are currently unidentifiable.

Abstract
Laboratory animals are used for scientific research in various fields. In recent years, there has been a concern that the gut microbiota may differ among laboratory animals, which may yield different results in different laboratories where in-vivo experiments are performed. Our knowledge of the gut microbiota of laboratory-reared common marmosets (Callithrix jacchus) is limited; thus, in this study, we analyzed the daily changes in fecal microbiome composition, individual variations, and effects of the birth facility in healthy female laboratory-reared marmosets, supplied by three vendors. We showed that the marmoset fecal microbiome varied among animals from the same vendor and among animals from different vendors (birth facility), with daily changes of approximately 37%. The fecal microbiome per vendor is characterized by alpha diversity and specific bacteria, with Bifidobacterium for vendor A, Phascolarctobacterium for vendor B, and Megamonas for vendor C. Furthermore, we found that plasma progesterone concentrations and estrous cycles were not correlated with daily fecal microbiome changes. In contrast, animals with an anovulatory cycle lacked Megamonas and Desulfovibrio bacteria compared to normal estrous females. This study suggests that the source of the animal, such as breeding and housing facilities, is important for in-vivo experiments on the marmoset gut microbiota.

Abstract
Chronic gastrointestinal (GI) diseases are the most common diseases in captive common marmosets. To understand the role of the microbiome in GI diseases, we characterized the gut microbiome of 91 healthy marmosets (303 samples) and 59 marmosets diagnosed with inflammatory bowel disease (IBD) (200 samples). Healthy marmosets exhibited "humanized," Bacteroidetes-dominant microbiomes. After up to 2 years of standardized diet, housing and husbandry, marmoset microbiomes could be classified into four distinct marmoset sources based on Prevotella and Bacteroides levels. Using a random forest (RF) model, marmosets were classified by source with an accuracy of 93% with 100% sensitivity and 95% specificity using abundance data from 4 Prevotellaceae amplicon sequence variants (ASVs), as well as single ASVs from Coprobacter, Parabacteroides, Paraprevotella, Phascolarctobacterium, Oribacterium and Fusobacterium. A single dysbiotic IBD state was not found across all marmoset sources, but IBD was associated with lower alpha diversity and a lower Bacteroides:Prevotella copri ratio within each source. IBD was highest in a Prevotella-dominant cohort, and consistent with Prevotella-linked diseases, pro-inflammatory genes in the jejunum were upregulated. RF analysis of serum biomarkers identified serum calcium, hemoglobin and red blood cell (RBC) counts as potential biomarkers for marmoset IBD. This study characterizes the microbiome of healthy captive common marmosets and demonstrates that source-specific microbiomes can be retained despite standardized diets and husbandry practices. Marmosets with IBD had decreased alpha diversity and a shift in the ratio of Bacteroides:Prevotella copri compared to healthy marmosets.

Abstract
Disruption of microbial communities within human hosts has been associated with infection, obesity, cognitive decline, cancer risk and frailty, suggesting that microbiome-targeted therapies may be an option for improving healthspan and lifespan. The objectives of this study were to determine the feasibility of delivering fecal microbiota transplants (FMTs) to marmosets via oral gavage and to evaluate if alteration of the gut microbiome post-FMT could be achieved. This was a prospective study of marmosets housed at the Barshop Institute for Longevity and Aging Studies in San Antonio, Texas. Eligible animals included healthy young adult males (age 2-5 years) with no recent medication use. Stool from two donors was combined and administered in 0.5 ml doses to five young recipients once weekly for 3 weeks. Safety outcomes and alterations in the gut microbiome composition via 16S ribosomal RNA sequencing were compared at baseline and monthly up to 6 months post-FMT. Overall, significant differences in the percent relative abundance was seen in FMT recipients at the phylum and family levels from baseline to 1 month and baseline to 6 months post-FMT. In permutational multivariate analysis of variance analyses, treatment status (donor vs. recipient) (p = .056) and time course (p = .019) predicted β diversity (p = .056). The FMT recipients did not experience any negative health outcomes over the course of the treatment. FMT via oral gavage was safe to administer to young adult marmosets. The marmoset microbiome may be altered by FMT; however, progressive changes in the microbiome are strongly driven by the host and its baseline microbiome composition.

Abstract
The genus Bifidobacterium is purported to have beneficial consequences for human health and is a major component of many gastrointestinal probiotics. Although species of Bifidobacterium are generally at low relative frequency in the adult human gastrointestinal tract, they can constitute high proportions of the gastrointestinal communities of adult marmosets. To identify genes that might be important for the maintenance of Bifidobacterium in adult marmosets, ten strains of Bifidobacterium were isolated from the feces of seven adult marmosets, and their genomes were sequenced. There were six B. reuteri strains, two B. callitrichos strains, one B. myosotis sp. nov. and one B. tissieri sp. nov. among our isolates. Phylogenetic analysis showed that three of the four species we isolated were most closely related to B. bifidum, B. breve and B. longum, which are species found in high abundance in human infants. There were 1357 genes that were shared by at least one strain of B. reuteri, B. callitrichos, B. breve, and B. longum, and 987 genes that were found in all strains of the four species. There were 106 genes found in B. reuteri and B. callitrichos but not in human bifidobacteria, and several of these genes were involved in nutrient uptake. These pathways for nutrient uptake appeared to be specific to Bifidobacterium from New World monkeys. Additionally, the distribution of Bifidobacterium in fecal samples from captive adult marmosets constituted as much as 80% of the gut microbiome, although this was variable between individuals and colonies. We suggest that nutrient transporters may be important for the maintenance of Bifidobacterium during adulthood in marmosets.

Abstract
Hemoplasmas, the erythrocyte-associated mycoplasmas, have been detected in several primates, causing mostly subclinical infection. This study aimed to determine the prevalence of hemoplasma infection in captive and free-ranging monkeys from southern Brazil, as well as factors and hematological abnormalities associated with infection. Blood samples from 40 non-human primates (NHP) were tested for hemoplasmas and coinfections. An overall of 10/40 (25.0%) NHP tested positive for hemoplasmas using PCR-based assays, including 9/14 (64.3%) black howler monkeys (Alouatta caraya) and 1/24 (4.2%) black-horned capuchin (Sapajus nigritus). Infection was not statistically associated with anemia, but wild-born monkeys and male black howler monkeys were more likely to be positive when compared with captive-born animals and female black howler monkeys, respectively. The sequences from the black howler monkey hemoplasma were similar (94% identity) to the squirrel monkey hemoplasma ("Candidatus Mycoplasma kahanei") and were phylogenetically located in a different cluster when compared to the human hemoplasma ("Candidatus Mycoplasma haemohominis").

Abstract
Identifying and refining small-animal models of tuberculosis that recapitulate aspects of human Mycobacterium tuberculosis infection can contribute to advancing our understanding of critical facets of the disease. To study the effects of very low-dose infections with 2 strains of M. tuberculosis on disease progression and survival in common marmosets, animals were challenged with strains Erdman and CDC1551 at doses ranging from 1 to 12 cfu. These data revealed that the susceptibility of marmosets to M. tuberculosis infection is influenced by strain virulence and initial dose. Marmoset infection with the Erdman strain, even at very low doses, resulted in rapid disease progression associated with severe weight loss, extensive pathology, and poor survival. By contrast, challenge with the less virulent CDC1551 strain resulted in slower disease progression, delayed weight loss, and prolonged survival. One marmoset infected with CDC1551 at a very low dose (approximately 1 cfu) was able to contain and control M. tuberculosis infection in a subclinical state that persisted as long as 300 d. These findings underscore the critical importance of understanding the heterogeneity in host outcome that can arise in association with different infectious doses and strains in the marmoset model of tuberculosis.

Abstract
Two captive cottontop tamarins (Sanguinus oedipus) died within 5 d of each other from systemic infection by Francisella tularensis (tularemia). One tamarin experienced mild clinical signs, including malaise, anorexia, and a mucoid nasal discharge for 4 d before death, whereas the other experienced a more rapid progression of disease that lasted less than 24 h. Differential diagnoses included gram-negative septicemia by an organism such as Escherichia coli, Salmonella, or Yersinia; protozoal infection such as Toxoplasma gondii or an acute viral infection such as lymphocytic choriomeningitis. F. tularensis infection was identified by F. tularensis-specific PCR in both primates. Possible sources of infection include aerosol, biting arthropod vectors, and transmission via a rodent reservoir. This case report highlights the importance of tularemia as a differential diagnosis in acute febrile illness in captive nonhuman primates.

Abstract
Mycobacterium tuberculosis infections can result in significant morbidity and mortality in nonhuman primate colonies. Preventative health programs designed to detect infection routinely include tuberculin skin testing (TST). Because Mammalian Old Tuberculin used for TST contains antigens common to a variety of mycobacterial species, false-positive results can occur in animals sensitized to nontuberculous mycobacteria (NTM). Over 11 mo, a large colony of common marmosets (Callithrix jacchus) demonstrated a 3.6% prevalence of equivocal or positive TST reactions (termed 'suspect reactions'). Culture of gastric aspirates, bronchoalveolar lavage fluid, and feces revealed a single animal with a positive fecal culture for Mycobacterium gordonae. PCR amplification of M. gordonae DNA in feces collected from animals with suspect TST reactions (demonstrating a 66.7% colonization rate) and colony controls (demonstrating a 14.3% colonization rate) revealed a significant association between suspect TST reactions and intestinal colonization. Gross and histopathologic evaluation revealed a multifocal lymphadenopathy and granulomatous lymphadenitis in 2 of 4 TST-positive marmosets examined. Counter to expectations, granulomatous lymphoid tissue was culture-positive for M. kansasii rather than M. gordonae. Detection of M. gordonae in the feces of TST-suspect animals likely represents an apathogenic intestinal colonization that may serve as an indicator of NTM exposure, whereas evidence of histopathologic disease is associated with the more pathogenic M. kansasii. Although a high index of suspicion for M. tuberculosis should always be maintained, colonization with NTM organisms represents a cause of suspect TST reactions in common marmosets.

Abstract
Enteropathogenic Escherichia coli (EPEC) strains are important agents of infantile diarrhea all over the world, gaining even greater importance in developing countries. EPEC have also been isolated from various animal species, but most isolates belong to serotypes that differ from those recovered from humans. However, it has been demonstrated that several isolates from non-human primates belong to the serogroups and/or serotypes related to those implicated in human disease. The objective of this study was to evaluate the genetic differences between thirteen strains isolated from non-human primates and the same number of strains isolated from human infections. Human isolates belonged to the same serogroup/serotype as the monkey strains and the evaluation was done by analysis of random amplified polymorphic DNA. Dendrogram analysis showed that there was no clustering between human and monkey strains. Human and non-human isolates of the EPEC serotypes O127:H40 and O128:H2 shared 90 and 87% of their bands, respectively, indicating strong genomic similarity between the strains, leading to the speculation that they may have arisen from the same pathogenic clone. To our knowledge, this study is the first one comparing genomic similarity between human and non-human primate strains and the results provide further evidence that monkey EPEC strains correlate with human EPEC, as suggested in a previous investigation.

Abstract
Francisella tularensis was identified as the cause of a die-off which occurred among a colony of semi-free-living common marmosets (Callithrix jacchus). During the outbreak 5 out of 62 animals died of tularaemia in a research facility located in the district of Goettingen, Germany. All animals had been born at the facility suggesting an endemic infection. A total of five culture isolates were recovered and characterized as F. tularensis holarctica, biovar I. These cultures represent the first isolates obtained in the Federal Republic of Germany for more than 45 years. The outbreak area shows several geographical and ecological characteristics known to favour long-term presence of F. tularensis. Persistence of the pathogen in the remote region along the former German-German border, continuous re-introduction from eastern European countries after destruction of the 'Iron curtain' or introduction through migrating birds are testable hypotheses which could explain the emergence of tularaemia in this particular region.

Abstract
An unusual Gram-negative, catalase- and oxidase-positive, rod-shaped bacterium isolated from different clinical samples from two monkeys (Callithrix geoffroyi) was characterized by phenotypic and molecular genetic methods. The micro-organism was tentatively identified as a Pseudomonas species on the basis of the results of cellular morphological and biochemical tests. Fatty acid studies confirmed this generic placement and comparative 16S rRNA gene sequencing studies demonstrated that the unknown isolates were phylogenetically closely related to each other (100 % sequence similarity) and were part of the ‘Pseudomonas fluorescens intrageneric cluster’. The novel bacterium, however, was distinguished from other phylogenetically related species of Pseudomonas by DNA–DNA hybridization studies and biochemical tests. On the basis of both phenotypic and phylogenetic findings, it is proposed that the novel Pseudomonas isolates are classified as Pseudomonas simiae sp. nov. The type strain of P. simiae is OLiT (=CCUG 50988T=CECT 7078T).

Abstract
The subjects of the study were 1,249 primates of different species, kept in a nursery in the city of Adler. The subjects varied in age, were either clinically healthy, diseased, or dead (the death had been caused by an acute intestinal disease). Biological, molecular-genetic (PCR), and immunological (coagglutination reaction) methods were used in diagnostics of campilobacter infections. The study found campilobacter in 20.9% of healthy animals on the average; this number varied depending on the species and age. The frequency of campilobacter infection in diseased and dead animals was higher than that in healthy ones (40.1% and 20.9%, respectively.) Two types of Campilobacter were identified: C. jejuni (73.4% of cases), and C. coli (14.2%). Clinical and pathomorphological manifestations of campilobacteriosis in primates and humans are similar. The portion of campilobacteriosis in acute intestinal diseases of primates is 40.1%.

Abstract
The intestinal microflora of common marmosets and rhesus monkeys were compared by enumerating bacteria from the small and large intestines. Rhesus monkeys had a consistent microflora pattern manifest by higher concentrations of total and Gram-negative aerobic and facultatively anaerobic bacteria, as well as aerobic and anaerobic Lactobacilli, in the large intestine as compared to the small intestine. In contrast, the marmoset microflora were considerably more variable. Approximately two-thirds of the marmosets (designated group A) had an overall profile that resembled the rhesus monkeys, but they had significantly higher concentrations of Gram-negative microflora in their large intestines than the rhesus monkeys. The remaining marmosets (group B) had higher concentrations of bacteria in the small intestine as compared to the large intestine, with the large intestinal concentrations being significantly lower than in the rhesus monkeys and group A marmosets. Moreover, the marmosets did not have detectable levels of aerobic Lactobacilli, and anaerobic Lactobacilli concentrations were significantly lower than in the rhesus macaques. Although it is unknown why microflora differ across species, it is likely that evolutionary adaptations in anatomy and functioning of the gastrointestinal tract influence the concentration and types of bacteria residing as the normal intestinal microflora.

Abstract
Specific clonal types of Actinobacillus actinomycetemcomitans, a major human periodontal pathogen, may be responsible for clinical manifestations and the production of leukotoxin virulence factors. Leukotoxicity is associated with genetic polymorphism at the promoter region of the leukotoxin (lItx) gene. Here, we describe the use of arbitrarily primed polymerase chain reaction (AP-PCR) and ltx promoter PCR to molecularly characterise 35 A. actinomycetemcomitans Brazilian isolates: 21 of human origin and 14 from captive marmosets (Callitrix spp., primates commonly used as animal models for periodontal research). The discriminative capacity of each of 12 arbitrary primers was found to be variable, yielding between 3 and 24 PCR amplitypes. Combination of the results for all primers led to characterisation of 14 genotypes that grouped into four major clusters based on genetic similarity. Clusters 2, 3, and 4 were discriminative to host origin. A correlation with periodontal disease was suggested for strains belonging to clusters 3 and 4. The JP2-like PCR amplification pattern, associated with highly leukotoxic strains, was exclusive to human isolates and present in 29% of human isolates where it occurred in close relationship with AP genotypes L and J (cluster 3).

Abstract
The ability of Actinobacillus actinomycetemcomitans to produce bacteriocin has rarely been reported. Antagonistic substance production may confer an important ecological advantage for the producer microorganisms, especially in a competitive ecosystem such as the oral cavity. In the present study, 75 A. actinomycetemcomitans strains isolated from the oral cavity of human patients with periodontal disease, periodontally healthy subjects and marmosets, as well as two reference strains (A. actinomycetemcomitans ATCC 29523 and FDC Y4) were evaluated for auto-, iso-, and heteroantagonistic activity. Fifty-one (68.00%) strains exhibited antagonistic activity; heteroantagonism was observed more often than isoantagonism. Isolated strains antagonized 17 different species of gram-positive and gram-negative bacteria from the oral and nonoral microbiota. Sensitivity to heat and to proteolytic enzymes constituted strong evidence that the antagonistic substance has a proteic nature. Taken together, our data enabled us to confirm that the antagonistic substance detected was a bacteriocin. The wide spectrum of activity indicates the possibility that more than one antagonistic substance is produced and that these substances play an important role in the ecological balance of the oral ecosystem.

Abstract
A case of zoonotic Mycobacterium tuberculosis infection in a marmoset (Callithrix jacchus) is reported. Genomic typing of the relevant M. tuberculosis isolates strongly suggests that the marmoset, which was kept as companion animal, acquired the disease from an infected member in the household who had been treated for pulmonary tuberculosis 8 years prior to this case.

Abstract
We describe the necropsy results from three common marmosets presented during an outbreak of hemorrhagic diarrhea in a colony of 230 common marmosets (Callithrix jacchus). Necropsy revealed consistent hemorrhagic typhlocolitis and variable ileitis associated with gram-negative bacilli closely adherent to enterocytes. Electron microscopy revealed bacilli attached intimately to shallow cup-like projections of enterocyte apical membranes with loss of microvilli (attaching and effacing). Escherichia coli isolates from affected marmosets were serogroup O26 and were positive for the E. coli attaching and effacing locus and negative for shiga-like toxin I and II, heat-stable enterotoxins a and b, and heat-labile enterotoxin by DNA probe hybridization. Results of a Vero cell cytotoxicity assay confirmed that the E. coli isolates did not produce shiga-like toxin. The increased availability of diagnostic probes for specific virulence factors such as attaching and effacing E. coli should lead to a greater understanding of the frequency of E. coli as a cause of diarrhea in nonhuman primates.

Abstract
The purpose of this study was to determine the in vitro activity of cefoxitin and imipenem against strains of the Bacteroides fragilis group isolated from the intestinal tract of humans and Callithrix penicillata marmosets. The majority of the human and marmosets B. fragilis strains was resistant to cefoxitin. The percentages of resistance to cefoxitin among B. fragilis marmoset strains were higher than those of human origin. On the other hand, the majority of the other Bacteroides of the B. fragilis group isolated from human and marmosets were susceptible to this drug. Imipenem was the most effective beta-lactam drug in this study, and we detected no resistance.

A strain of Bacteroides fragilis, isolated from the marmoset Callithrix penicillata, produced protein(s) with bacteriocin activity (fragicilin). Two active fractions (36 and 150 kDa) were isolated by chromatography. The bacteriocin exhibited iso- and heteroantagonism. It remained stable between pH 3 and 10 and at 60 degrees C for 24 h. Pronase, trypsin, proteinase K and type VII protease inactivated the bacteriocin, giving evidence of its protein nature.

Abstract
Two young male common marmosets (Callithrix jacchus) were injected intracerebrally and intraperitoneally with a crude brain homogenate prepared from a cow with bovine spongiform encephalopathy (BSE). Two other marmosets were similarly injected with brain homogenate from a sheep with natural scrapie. The two animals injected with scrapie material developed neurological signs 38 and 42 months after injection and the two animals injected with BSE material developed neurological signs after 46 and 47 months. Post mortem examination of the brains revealed spongiform encephalopathy especially in the basal nuclei and diencephalon of all the animals and, in addition, involvement of the cerebral cortex of the marmosets injected with scrapie material. The experiment extends the host range of experimental BSE to include a primate species.

Abstract
Six strains of serotypes 1 or 2 of Y. pseudotuberculosis were isolated from dead squirrel monkeys, a cotton-top tamarin and a marmoset hybrid. All strains harboured a 71.6 kb plasmid, all were totally oxacillin-resistant and partially resistant to cephalosporins. Biochemically, serotypes 1 and 2 differed from each other in their beta-galactosidase production in a nonfermenter system, whereas the lack of rhamnose, maltose, salicin and trehalose fermentation seemed to be attributable to technical causes.

An ELISA was developed for measuring serum antibodies against the arenavirus lymphocytic choriomeningitis virus (LCMV) and a closely related isolate termed callitrichid hepatitis virus (CHV). The ELISA was used to test sera from healthy adults and from hepatitis patients. In Birmingham, Alabama, the seropositivity rate for healthy black women was 5.1% (7/138), and the rate for patients with all types of hepatitis or cirrhosis was 4.3% (2/46). In San Antonio, Texas, the seropositivity rate among a clinical series of patients with non-A, non-B hepatitis was 0 (0/20), and the rate among persons rejected from blood donation because of high serum alanine aminotransferase levels was 2.4% (2/82). These results indicate that infection with LCMV or CHV is common in Birmingham but that infection is not associated with hepatitis.

Abstract
The ability of strains of the B. fragilis group, isolated from the oral cavity and intestine of marmosets, to produce bacteriorin-like substances in solid medium, in terms of auto-, iso- and heteroantagonism, was evaluated. Antagonistic activity was exhibited by 52% of the intestinal strains, 3 of which showed autoantagonistic activity. Three out of 9 oral strains isolated, tested against themselves, showed simultaneous isoantagonism to 4 indicator strains; but not autoantagonism. The same 9 oral strains, when tested against 16 reference strains, revealed interspecific activity only against 2 Gram-positive microorganisms. Higher activity, evaluated by the size of the inhibition halo, was observed in BHI-S agar, and greatest inhibition was obtained after 72 h of incubation.

Abstract
The ability of engineering variants of hepatitis A virus (strain HM175) to replicate in cell culture or to cause disease in marmosets was evaluated. Virus variants were encoded by chimeric genomes constructed from infectious cDNA clones of two viruses (wild type and cell-culture-adapted) which differed in their ability to grow in vitro and to cause acute hepatitis in marmosets. Transfection and infectivity assays indicated that virus growth in vitro could be enhanced by subcloning the cell substrate prior to infection or by introducing multiple combinations of two or more mutations into the wild type genome. Various chimeric viruses induced liver enzyme elevations in marmosets, indicating that attenuation of virulence also required multiple mutations.

Abstract
Thirty-five strains of the Bacteroides fragilis group were isolated from oral and intestinal samples from 5 wild caught, captive Callithrix penicillata. Nine oral strains of Bacteroides fragilis (7) and Bacteroides distasonis (2), and 26 intestinal strains of Bacteroides fragilis (14) and Bacteroides distasonis (12) were identified.

Abstract
To obtain definitive evidence that milk-borne infection plays a critical role in the endemy or mother-to-child transmission of human T-cell leukemia virus type-I (HTLV-I), we inoculated concentrated fresh human milk cells obtained from HTLV-I carrier mothers into the oral cavity of a common marmoset (Callithrix jacchus). Twenty-eight milk samples were collected (5-10 ml each) from 17 carrier mothers in the first week after delivery. Cells in the milk were centrifuged down and resuspended in 1/10 vol of the milk fluid. The concentrated cell suspensions were successively inoculated into the oral cavity of a common marmoset. The marmoset was found to be seroconverted by indirect immunofluorescence assay at 2.5 months after the first inoculation of the milk (3.5 X 10(8) cells in total), and was later confirmed to be infected with HTLV-I by the detection of viral antigen expression in short-term cultures of its peripheral blood T-lymphocytes. The results strongly support the working hypothesis that milk-borne infection plays a significant role in the mother-to-child transmission of HTLV-I.

Abstract
Twenty marmosets, male Callithrix jacchus, were used during this study. Fifteen of the marmosets were inoculated with 5,000 TCID50 of the attenuated XJC13 strain of Junin virus by intramuscular route and five were left as uninoculated controls. Animals were observed for a 420-day period. In order to carry out virologic, hematologic, serologic, and histologic studies the animals were bled and/or killed at different days post infection(pi). Results obtained showed that the attenuated strain produced an infection with no mortality or signs of illness. There was only a slight loss of weight at 18-40 days pi, which was soon recovered. Viremia was present from day 6 to 22, titers peaking at 4.0 log. Viral spread was limited to the lungs, spleen, lymph nodes, and bone marrow in the animal killed on day 14. No virus was found in the organs of the animal killed on day 23, and neither hematologic alterations nor pathologic lesions were seen in these monkeys except for ganglionar hypertrophy with immunoblast proliferation. Antigen was detected by immunofluorescence (IF) in lymph nodes, spleen, adrenals, lungs and brain. Neutralizing antibodies were detected from the third week onward. Protection conferred by the XJC13 strain proved effective when XJC13-inoculated monkeys were challenged with 1,000 TCID50 of the pathogenic XJ strain at days 60 or 380 pi, while normal controls died. When viral persistence was searched for on days 370, 390, and 420 pi, no infectious virus was detected, but viral antigen was seen in certain organs, which, however, lacked tissue damage.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Infection of Callithrix jacchus, a New World primate, with the prototype strain of Junin virus produced a severe disease. The animals developed multifocal hemorrhages and characteristic microscopic lesions such as meningoencephalitis, interstitial pneumonia, lymphocytic depletion of lymphatic tissue, hepatocytic necrosis, and a variable decrease in bone marrow cellularity. High virus concentrations correlated with lesions, and with the presence of viral antigenic determinants as revealed by immunofluorescent methods. With the exception of central nervous system damage, the morphological features and immunohistochemical and viral findings were similar to those recorded in human Argentine hemorrhagic fever.
