Abstract
We report an autopsy case of rapid progressive Waterhouse-Friderichsen syndrome (WFS) associated with Streptococcus pneumonia infection in a previously healthy man. Although he once visited a hospital about 6 hours before death, the both physical and serological examination did not show any sign of overwhelming infection. Autopsy showed massive adrenal hemorrhage without inflammation, and showed proliferation of gram positive cocci and microthrombosis in the vessels of many organs. The pathological change of respiratory tract was extremely minimal. Size and weight of the spleen possible decreased than normal. However, histological examination showed that obscuration of germinal center and decreasing the immunological cells of mantle and marginal zone. Immunohisitochemically, marked decreasing the marginal zone macrophages, which are positive for specific intercellular adhesion molecule grabbing nonintegrin receptor-1 (SIGN-R1) and macrophage receptor with collagenous structure (MARCO), were decreased comparing with age-matched control case. Polymerase chain reaction (PCR) assay using each DNA, extraction from formalin-fixed paraffin-embedded specimen (FFPE) samples of lung, adrenal gland, heart, spleen, and kidney showed positive the ply gene and the lytA gene specific for Streptococcus pneumonia. Present case showed possible acquired atrophy of spleen, especially decreasing marginal zone macrophage may correlate with rapid progression of sepsis of Streptococcus pneumonia with massive adrenal hemorrhage. In addition, present case showed the usefulness of PCR using FFPE for the postmortem diagnosis of WFS.

Abstract
This report documents a case of isolated adrenal gland cryptococcosis without the often reported component of concomitant meningitis or Addison's disease in an immune competent patient. Furthermore, both the patient's lung cancer and adrenal infection with cryptococcus were incidentally discovered during work-up for syncope in the setting of hyponatremia. This case also underscores the diagnostic value of fine-needle aspiration biopsy in this unusual presentation.

Abstract
Microsporidiosis is reported rarely in reptiles. Sporadic multisystemic granulomatous disease of captive bearded dragons (Pogona vitticeps) has been associated with microsporidia showing Encephalitozoon-like morphology. Two such cases are described herein. Both animals displayed clinical signs suggestive of renal failure. Necropsy examination revealed granulomatous lesions in the liver and adrenal area in both animals, and in several other organs in one animal. The lesions were associated with intracellular protozoa consistent with microsporidia. Ultrastructural examination of the organisms revealed morphology similar to Encephalitozoon spp. Immunohistochemistry and chromogenic in-situ hybridization for Encephalitozoon cuniculi were positive in both animals. Nucleotide sequencing of the partial small subunit ribosomal RNA gene and the complete internal transcribed spacer (ITS) region revealed high similarity with published E. cuniculi sequences in both animals. However, the ITS region showed a GTTT-repeat pattern distinct from mammalian E. cuniculi strains. This may be a novel E. cuniculi strain associated with multisystemic granulomatous disease in bearded dragons.

Abstract
Experiments on 55 male chinchilla rabbits with model widespread purulent peritonitis have been performed for determinig structural changes in adrenal glands with the aid of optical microscopy. The introduction of aerobic-anaerobic culture of E. Coli and B. Fragilis into the abdominal cavity causes expressed structural changes in parenchyma of adrenal glands within 6 hours. It is established for the first time that the administration of metabolic drugs citoflavin (containing succinic acid) and neoton (containing creatine phosphate) prevents the development of pathological structural changes in adrenal glands under conditions of experimental widespread purulent peritonitis.

Abstract
Systemic mycobacteriosis associated with avian polyomavirus infection was diagnosed histologically in an 8-year-old, captive European goldfinch with a history of nervous signs. Severe mycobacterial lesions were observed in the central nervous system, lungs, cervical air sacs and adrenal glands, without involvement of the gastrointestinal tract. In addition to mycobacteriosis, intranuclear inclusions, typical of polyomavirus, were identified in the adrenal glands. Polymerase chain reaction assays were used to identify Mycobacterium genavense and finch polyomavirus as the causative agents. The absence of involvement of the gastrointestinal tract and the severity of the lesions in the respiratory tract suggested that inhalation may have been the primary route of infection with M. genavense.

Abstract
The paper presents a note of adrenal tuberculosis. The latter is difficult to diagnose and even a large lesion cannot be diagnosed by traditional means. Computed tomography fails to differentiate a tumor process from specific inflammation. The diagnosis can be verified only when invasive procedures are applied and in cases of destructive lesion or suspected tumor adrenalectomy is not only a diagnostic, but also therapeutic technique.

Abstract
We report a case of non-typhi Salmonella adrenal abscess in a patient with human immunodeficiency virus (HIV) infection and thalassaemia minor. Non-typhi Salmonella bacteraemia is common in HIV-infected patients, but infection localized in the adrenal gland is rare. Focal salmonellosis is common in haemoglobinopathy but unusual in thalassaemia minor. This patient was diagnosed by computed tomography (CT) guided aspiration and successfully treated with ciprofloxacin.

Abstract
Histoplasma capsulatum was isolated from the spleen of a first infected mara (Dolichotis patagonum) and from a second mara's liver and adrenal gland, both in the same colony at the Africam Safari, Puebla, Mexico. Studies of H. capsulatum isolates, using nested-PCR of a 100-kDa protein coding gene (Hcp100) fragment and a two-primer RAPD-PCR method, suggest that these isolates were spreading in the environment of the maras' enclosure. By using a Dot-ELISA method, sera from mice inoculated with three homogenates of soil samples from the maras' enclosed space developed positive brown spot reactions to a purified H. capsulatum antigen, which identified the probable source of the maras' infection.

We report a case history of an 84-year-old elderly male patient that presented with a clinical picture suggestive of adrenal failure and bilateral adrenal nodules detected by abdominal computed tomography. A fine needle-guided biopsy was inconclusive for achieving a final diagnosis. The patient died due to septic shock and the autopsy disclosed histoplasmosis with extensive bilateral necrosis of the adrenal glands. Although the adrenal involvement in chronic disseminated histoplasmosis has been described, there have been few reports of the infection being associated with adrenal insufficiency.

Abstract
Functional interactions between neuroendocrine and immune systems are mediated by similar ligands and receptors, which establish a bi-directional communication that is relevant for homeostasis. We investigated herein the hypothalamus-pituitary-adrenal (HPA) axis in mice acutely infected by Trypanosoma cruzi, the causative agent of Chagas' disease. Parasites were seen in the adrenal gland, whereas T. cruzi specific PCR gene amplification product was found in both adrenal and pituitary glands of infected mice. Histological and immunohistochemical analyses of pituitary and adrenal glands of infected animals revealed several alterations including vascular stasis, upregulation of the extracellular matrix proteins fibronectin and laminin, as well as T cell and macrophage infiltration. Functionally, we detected a decrease in CRH and an increase in corticosterone contents, in hypothalamus and serum respectively. In contrast, we did not find significant changes in the amounts of ACTH in sera of infected animals, whereas the serum levels of the glucocorticoid-stimulating cytokine, IL-6 (interleukin-6), were increased as compared to controls. When we analyzed the effects of T. cruzi in ACTH-producing AtT-20 cell line, infected cultures presented lower levels of ACTH and pro-opiomelanocortin production when compared to controls. In these cells we observed a strong phosphorylation of STAT-3, together with an increased synthesis of IL-6, suppressor of cytokine signaling 3 (SOCS-3) and inhibitor of activated STAT-3 (PIAS-3), which could explain the partial blockage of ACTH production. In conclusion, our data reveal that the HPA axis is altered during acute T. cruzi infection, suggesting direct and indirect influences of the parasite in the endocrine homeostasis.

Abstract
BACKGROUND Recombinant adenoviruses are widely used in gene therapy clinical trials. A particular tropism for the adrenal glands has been reported but the precise cellular base for this tropism has not been determined. MATERIALS AND METHODS Recombinant adenoviruses were injected intravenously into Balb/c nu/nu or C57BL/6 mice. Seventy-two hours later, the animals were sacrificed and the adrenal glands and livers collected. The glands were sectioned and analyzed using immunohistochemical methods to detect adenoviral epitopes and transgene expression. Total RNA were extracted from the liver and adrenal glands of some animals and subjected to real-time RT-PCR. RESULTS The only cell type infected in the adrenal glands of Balb/c nu/nu or C57BL/6 mice is the adrenocortical cells in the zona fasciculata. Quantitatively, the relative level of gene expression in the adrenal gland is comparable but lower than that measured in the liver. CONCLUSIONS Systemic injection of recombinant adenovirus could be used as a procedure to restore adrenal steroidogenesis in clinical gene therapy protocols. In addition, our study suggest that adrenal dysfunction should be considered when criteria are established to assess the safety of gene therapy formulations administered systemically.

Abstract
A morphologic evaluation was carried out on adrenal glands from 128 autopsied patients with the acquired immunodeficiency syndrome (AIDS). The adrenal gland was compromised in 99.2% of the cases, with distinct pathological features and infectious agents. Inflammatory infiltrates were observed in 99.2% of the cases with a predominance of mononuclear cells in 97.4%, affecting mainly the medulla. Necrosis, fibrosis, hemorrhages and neoplasias were observed. We also described 3 (2.3%) cases of calcification located in the adrenal gland central vein (AGCV). This is seldom mentioned in the literature. Cytomegalovirus was the most frequent infectious agent, observed in 48.4% of cases. Balamuthia mandrillaris, a free living ameba, was found in one case affecting the entire gland. We also found a nest of Trypanosoma cruzi in the musculature of the AGCV. The presence of the nest of T cruzi in AGCV may play a role in the reactivation of this infection in immunosuppressed individuals. Pathologic processes and opportunistic infections may contribute to the alterations in the adrenal gland that lead to multiple organ failure observed in terminal AIDS patients.

Abstract
Pneumocystis carinii is primarily an opportunistic pathogen infecting patients with AIDS and other immunocompromised patients, and ordinarily does not affect immunocompetent persons. We report isolated P. carinii infection of bilateral adrenal glands in a non-immunocompromised adult male, leading to fatal Addisonian crisis. Diagnosis of P. carinii was established on the basis of cytopathology and microbiological tests, using conventional staining techniques and direct immunofluorescence on ultrasound-guided fine needle aspirates and trucut needle biopsy specimen from adrenal glands. P. carinii pneumonia and other fungal infections of the adrenal glands were excluded by appropriate tests. Absence of HIV infection was established by negative ELISA for HIV I and II antibodies and Western blot analysis at the time of presentation and 45 d later. Normal blood total leukocyte and CD4 lymphocyte counts and IgG and IgA levels confirmed the immunocompetent status of the patient. The patient improved with anti-Pneumocystis treatment and corticosteroid replacement, but succumbed to an episode of Addisonian crisis triggered by a diarrheal illness.

Abstract
Paracoccidioides brasiliensis is a dimorphic fungus presenting specific steroid hormone receptors, both in the yeast and mycelial forms and estrogen inhibits the transition from mycelium to yeast. In the acute phase, the disease occurs with equal frequency in both sexes but in adults, females are spared. Placental fungal infection has been reported, but references to fetal infection have not been confirmed. We used 78 Syrian female hamsters divided into 3 groups: GI consisted of 30 infected mated females, GII of 20 infected unmated females and GIII of 28 uninfected mated females. Animals of group I were mated 4 weeks after infection and half of them were submitted to cesarean section on day 15 after successful mating; the other half was maintained and submitted to cesarean section and sacrificed 14 weeks after infection. Half of the animals of group II were sacrificed seven weeks and the other half 14 weeks after infection. Uninfected animals of group III were treated the same as the animals of group I. The animals were infected with strain 18 of P. brasiliensis by the intracardiac route. We evaluated the disease by the volume of granulomas in different organs, number of fungi in liver and spleen and the immunologic responses [ELISA, Double Immunodifusion (DID), Delayed Hypersensitivity Skin Test (DHT) and Macrophage Migration Inhibition (MMI)]. We studied the infection through the gestation by evaluation of the abortions, morphologic and clinic examinations of the fetuses. Our results showed that the infection did not transfer to the fetus through the placenta, but the number of abortions was larger among infected females. The newborns of GI females were smaller, weighed less and showed little vitality. The disease was more severe and disseminated in infected mated females, especially in the second sacrifice 14 weeks after inoculation, when the total volume of granulomas in them (56.3 mm) was much greater than in the infected unmated females (12 mm).

Abstract
Human blood collected from two patients from Westchester County, New York with human granulocytic ehrlichia (HGE) infection was inoculated into two ponies. Inoculated ponies developed clinical signs similar to a previous report (Madigan et al., 1995). Histopathological changes involved follicular hyperplasia of lymphoid tissues. HGE DNA was detected by PCR in muscle, fascia, peritoneum, and adrenal gland after the ponies produced a high level of antibodies to HGE. We suggest that HGE may reside in poorly vascularized connective tissues, where the antibodies may have some difficulties to penetrate, resulting in persistent infection. Since HGE and E. equi cause very similar diseases in both humans and horses, they may be the same organism with minor genetic differences.

Abstract
A case of primary adrenal insufficiency with bilateral adrenal masses and meningitis due to disseminated cryptococcosis in a patient with mild non-insulin-dependent diabetes is presented. The diagnosis was made by fine-needle aspiration biopsy cytology. Although the meningitis responded to antifungal therapy, the bilateral adrenal gland enlargement did not change. Reflecting this, cryptococcal antigen titers became negative in CSF, but fell to 1:8 in serum. Although antifungal therapy continued, cryptococcal antigen titer increased both in CSF and serum for 50 days. Because the adrenal glands were the apparent focus for the persistent fungemia, bilateral adrenalectomy was performed. Antifungal therapy for an additional 15 months was needed to achieve negative serum cryptococcal antigen titers. Although adrenal insufficiency due to disseminated cryptococcosis is rare in healthy hosts, it should be included in differential diagnosis of unilateral and bilateral adrenal masses.

Abstract
Cytomegalovirus is transmitted with blood and organs from seropositive individuals, although the particular leukocyte population harboring latent or persistent virus remains poorly characterized. Murine cytomegalovirus, tagged with the Escherichia coli lacZ gene, was used to identify cells in which virus replicates during acute infection of immunocompetent mice. Recombinant murine cytomegaloviruses, RM461, RM460, and RM427, were constructed to express beta-galactosidase under control of the human cytomegalovirus ie1/ie2 promoter/enhancer. The lacZ gene was inserted between the ie2 and sgg1 genes in RM461 and RM460, disrupting a 0.85-kb late transcript that was found to be dispensable for replication in cultured cells as well as for infection of mice. In BALB/c mice, lacZ-tagged and wild-type viruses exhibited a similar 50% lethal dose and all had the capacity to latently infect the spleen. Peripheral blood mononuclear phagocytes were the major infected leukocyte cell type, as demonstrated by the ability of infected cells to adhere to glass and to phagocytize latex beads; however, these cells did not exhibit typical monocyte markers. Plaque assay for virus and 5-bromo-4-chloro-3-indolyl-beta-D-galactopyranoside (X-Gal) staining of frozen sections of organs from infected mice revealed that the major target organs included the spleen, adrenal glands, liver, and salivary glands, although tissues as diverse as brown fat and lungs were also involved. Individual blue-staining cells were readily identified in all infected tissues. These studies identified a mononuclear phagocyte, possibly a macrophage or dendritic cell precursor, as the vehicle of virus dissemination during acute infection, and demonstrate the utility of using lacZ-tagged murine cytomegalovirus for tropism, pathogenesis, and latency studies.

Abstract
Two murine monoclonal antibodies (MAbs) specific to Paracoccidioides brasiliensis (as determined by enzyme-linked immunosorbent assay [ELISA] and Western blot [immunoblot]) were produced by using a modification of standard hybridization protocols, with cyclophosphamide included as an immunomodulator to abolish responses to highly cross-reactive immunodominant epitopes. MAbs PS14 and PS15 are two different clones which exhibit similar characteristics by ELISA and Western blot. They are directed against a 22- to 25-kDa antigen which is present in P. brasiliensis and which could not be identified in other dimorphic fungi by ELISA or Western blot. Partial purification of the antigen was accomplished by isoelectric focusing, and deglycosylation studies suggested that the 22- to 25-kDa antigen is a glycoprotein with a pI of between 4.5 and 5 and that O-linked sugars may be part of the recognized epitope. The MAbs stained the cytoplasm of P. brasiliensis yeast and hyphal cells in cryostat sections of fresh cultures of the fungus. In addition, the MAbs stained the wall of paracoccidioidomycotic granulomas, as well as the cytoplasm of the fungus, as determined by the use of immunofluorescence, immunoperoxidase, and immuno-alkaline phosphatase staining techniques in paraffin-embedded sections of human biopsy material, and they failed to stain granulomas resulting from other clinical conditions. These findings suggest that these MAbs have potential use in the immunohistochemical identification of P. brasiliensis.

Abstract
A comparison of the pathogenicity in mice of the recombinant herpes simplex virus type 1 (HSV-1) strain HSV-1-M-LacZ, in which the UL56 gene has been deleted, was made with its parental strain F, following infection in different mouse strains. The polymerase chain reaction (PCR) technique was used to study the migration of virus DNA in the mouse model. Tissues from adult mice infected intraperitoneally (IP) with one of three HSV-1 strains (F, HFEM or HSV-1-LacZ) were examined for the presence of viral DNA. DNA of the pathogenic strain F was detected in the adrenal glands, spinal cord, brain, liver and pancreas. DNA of HSV-1-M-LacZ was detected in the same tissues. However, DNA of the apathogenic strain HFEM was detected transiently (on days 2 and 3 p.i., but not days 1, 5 or 7), only in the adrenal glands and no viral DNA was detected in any of the other tissues. HSV-1 pathogenic strains injected intraperitoneally into newborn mice (7 days old) killed most of the mice. In the surviving mice viral DNA of the three virus strains was found in peritoneal exudate cells (PEC), adrenal glands, spinal cord, liver and spleen. It was found that HSV-1-M-LacZ, which lacks the UL56 gene, resembled in pathogenicity to the newborn mice the pathogenic HSV-1 strains F and KOS. The PCR technique was used to trace viral DNA in tissues of the mice which survived HSV-1 infection at 7 weeks of age. Only HSV-1 (KOS) DNA was detected in the pancreas. The brains of these mice did not contain viral DNA. It is suggested that HSV-1 DNA may reside in surviving HSV-1- infected newborn mice in a "latent" state in nonneural tissues.

Abstract
Non-neural tissues, from three male and four female stripped skunks (Mephitis mephitis), 5 to 7 months old, and one male and two female red foxes (Vulpes vulpes), 12 to 16 months old, experimentally infected with street rabies virus, were examined by light microscopic immunohistochemical and electron microscopic methods. This is the first report of ultrastructural lesions in rabies-infected adrenal medulla, cornea, and nasal glands. Using the streptavidin biotin peroxidase technique, antigen was detected in mucous cells and interstitial neurons and their processes in the submandibular salivary gland, in chromaffin cells of the adrenal medulla, in epidermal cells of the skin, in external root sheath cells of hair follicles, and in corneal epithelial cells. Electron microscopically, matrix (viral nucleocapsid), virions, and anomalous viral products were common in most tissues examined, but their relative proportions varied. The results suggested that replication with minimal accumulation of matrix and anomalous viral growth products was characteristic of growth in tissues (submandibular salivary gland) that frequently produce high titers of virus, whereas replication with large amounts of matrix and anomalous structures occurred in tissues (adrenal gland and nasal gland) that generally contained low or moderate titers of virus. Novel findings included viral budding into secretory granules, increase in microfilaments in infected mucogenic cells, and continuity of viral convoluted membranous profiles with rough endoplasmic reticulum of chromaffin cells and nasal glandular cells. The presence of viral antigen and developing virus in extra-neural tissues constitutes a potential risk of non-bite exposure to people in certain groups/occupations.

Abstract
Pichinde virus has been adapted to produce lethal infection of Strain 13 guinea pigs. Viral replication and presence of viral antigen in frozen tissues stained by immunofluorescence has been previously described. Further investigation into the pathogenesis of this disease has been hampered by the lack of a light microscopic method for correlating histologic lesions and the presence of Pichinde viral antigens. For this purpose, we developed a sensitive immunocytochemical technique for staining Pichinde viral antigens in formalin-fixed, paraffin-embedded tissue. Enhancement of the immunocytochemical staining with nickel chloride markedly improved detection of viral antigens. We examined frozen and formalin-fixed tissues from Strain 13 guinea pigs for viral antigens by light microscopy and immunocytochemistry at various intervals after infection with Pichinde virus. Progressive involvement of different tissues correlated with organ injury measured by serum biochemical abnormalities. Pichinde viral antigen was first detected in splenic macrophages five days after infection and their subsequent destruction facilitated persistent viremia. The inability to clear virus led to multiple organ infection and vascular involvement. Ensuing infections involved particularly the liver, spleen, adrenal glands, lungs, and intestines. Gastroenteritis developed, with extensive involvement of the muscularis mucosa throughout the gastrointestinal tract. Water and food intake decreased rapidly after day 8, leading to marked weight loss. Fatty changes of the liver suggested metabolic derangement that was further exacerbated terminally by adrenal infection and pulmonary impairment.

Abstract
Despite the great amount of literature concerning toxoplasmic encephalitis in AIDS patients, little is known about extracerebral toxoplasmosis. Therefore we conducted a study of 80 autopsy cases to estimate the frequency of extracerebral toxoplasmosis. A control group of 50 cases was completely negative for all markers applied. In 35 of the 80 AIDS-cases (43.7%), organisms could be detected. In 13 cases (16.2%) there was an extracerebral toxoplasmosis; 4 cases (5%) showed only extracerebral involvement and in 9 cases (11.2%), extracerebral toxoplasmosis occurred in combination with cerebral manifestations. In 22 cases (27.5%), only cerebral toxoplasmosis was found. The following organs were involved: cardiac muscle (15%), lungs (6.2%), liver (5%), pancreas (5%), gastrointestinal tract (6.2%), adrenal glands (5%), lymph nodes (5%) and testis (3.7%). In individual cases further organs, not mentioned above, were involved. Pseudocysts could be demonstrated within necroses and inflammatory foci by conventional staining, whereas trophozoites became apparent only immunohistologically.

Abstract
OBJECTIVE To determine whether human adrenal cells can be infected by HIV. METHODS Cultured human fetal adrenal cells and the SW13 human adrenocortical carcinoma cell line were inoculated with several HIV-1 and HIV-2 strains. Virus replication was detected by viral core antigen enzyme-linked immunosorbent and reverse transcriptase assays. CD4 expression was measured by Northern blot and polymerase chain reaction procedures. RESULTS HIV infection of these adrenal cells was detected and was most evident after cocultivation of the inoculated cells with peripheral blood mononuclear cells. Infection does not involve the CD4 molecule, which is not expressed by these adrenal cells. The relative level of HIV replication depended on the viral strain used. Virus production occurred best in cells that maintained evidence of adrenal cell function. Infection did not appear to disturb steroidogenesis measured in the cells. CONCLUSIONS These observations indicate that human adrenal cells are susceptible to HIV infection, and provide further evidence of the polytropic nature of the virus.

Abstract
Helicobacter pylori colonizes the mucous layer of the stomach and the surface of gastric mucous cells. Although H. pylori is not generally thought of as invasive, it has been observed in the lamina propria and within vacuoles in the cytoplasm of epithelial cells. The authors report that isolates of H. pylori can enter into the cytoplasm of tissue culture epithelial cell lines such as HEp-2 cells. Intracellular uptake of H. pylori by HEp-2 cells is rapid and appears to require both the N-acetylneuraminyllactose-binding adhesin and another factor present only in living bacteria. Uptake of H. pylori was inhibited by ammonium chloride and chloroquine at concentrations that did not effect either adherence or bacterial viability. Dansylcadaverine, an inhibitor of receptor clustering and internalization, also inhibited uptake but not adherence of H. pylori. Uptake was completely inhibited when H. pylori and HEp-2 cells were incubated at 4 degrees C under conditions that did not effect bacterial adherence. Cytochalasin B, an inhibitor of phagocytosis, did not inhibit uptake. It is concluded that H. pylori is internalized either by receptor-mediated endocytosis or by a closely related pathway.

Abstract
The herpes simplex virus (HSV)-infected mouse model was used to correlate histopathological lesions in adrenal glands and ovaries with the localisation of viral nucleic acids and viral antigens, employing in situ hybridization and immunohistochemistry. In the adrenals, the lesions were mainly restricted to the zona fasciculata and the zona reticularis, sometimes extending to the medulla. In the ovaries, lesions were detected in follicles and in the stroma. During the course of infection, HSV nucleic acids could be detected earlier than HSV proteins. Next to the center of necrotic foci mainly HSV proteins were detected, whereas peripheral cells were found to contain viral nucleic acids. In situ hybridization revealed no proof of HSV latency in either organ. Among HSV-1 and HSV-2 strains of different neurovirulence, only HSV-2 variant ER- failed to replicate in adrenal glands and ovaries, whereas the neuroinvasive variant ER+ showed the same patterns as the HSV-1 strains used.

Abstract
In order to investigate whether or not the UL56 gene is involved in those processes determining the viral pathogenicity and latency, a recombinant virus HSV-1-M-LacZ was constructed in which the DNA sequences between nucleotide position (np) 116030 and 121753 were replaced by the E. coli beta-galactosidase (LacZ) gene. This deletion spans from the carboxyterminus of UL55 (np 116030) to the second exon of IE110 (np 121753) eliminating UL56 and the variable region of the BamHI DNA fragment B which were implicated in intraperitoneal pathogenicity and latency. The host range and growth kinetics of the recombinant virus HSV-1 M-LacZ were comparable to the parental strain HSV-1 F. As expected it was found that HSV-1-M-LacZ lost its virulent phenotype and was not able to develop acute infection in animals. The state of the UL56 gene was investigated by determining the cDNA sequence of the UL56 gene transcript of HSV-1 F using PCR products obtained after amplification of the cDNA with oligonucleotide primers corresponding to the translational start and stop codons of this gene. This analysis revealed that the DNA sequence of the UL56 gene of HSV-1 F differed from those DNA sequences determined for the genomic DNA of HSV-1 strain 17. Between nucleotide position 116343 and 116344 two nucleotides -AG- are inserted which prolong the ORF of the UL56 gene to 233 amino acids with a predicted molecular weight of 30 kDa.

Abstract
The relationship between paracoccidioidomycosis in ddY mouse and its estrous cycle was studied. Adult ddY mice of both sexes were used as experimental animals. Estrous cycle of female mice was examined before inoculation of Paracoccidioides brasiliensis yeast cells and mice were divided into 5 groups such as proestrus, estrus, metestrus-I, metestrus-II and diestrus. Each mouse was inoculated intravenously with 10(6) P. brasiliensis yeast cell units and sacrificed on day 28 after inoculation. Their internal organs were cultured, and in addition, their histopathologies were studied. As a result, there was no difference in the organ cultures among the male and the female mice of 5 groups. However, histopathologically, the female groups at estrus, metestrus-I and metestrus-II were affected more severely than the male group, and the susceptibility of the female mice to the fungus was closely related to their estrous cycles.

Abstract
By the application of in situ hybridization to thin sections of paraffin-embedded tissues we have been able to determine with high resolution the cell types containing lymphocytic choriomeningitis virus nucleic acid in the tissues of persistently infected mice. We confirm and extend previous observations of virus persistence in the brain, lung, liver, kidney, pancreas, thyroid and reticuloendothelial system. In addition, we demonstrate for the first time persistence of viral nucleic acid in specific cell types in the thymus, lymph nodes, testes and bladder, and the adrenal, parathyroid and salivary glands; the cell types infected were observed in several animals. In lymphoid tissue, viral nucleic acid was predominantly located in the T cell-dependent areas of the spleen and lymph nodes; it was also present in cells of the thymic medulla. This has important implications for the deficiency in T cell function observed in persistently infected mice. In the testes, viral nucleic acid was detected in spermatogonia but not differentiating spermatocytes and therefore, in this tissue at least, persistence is related to the state of differentiation of the cell. Endocrine and exocrine dysfunctions have been described in persistently infected mice and we report that the highest levels of viral nucleic acid were found in the adrenal gland. The infection of endocrine and exocrine tissue was not pantropic, specific cell types expressed viral nucleic acid in each tissue. In the adrenal cortex, cells of the zona reticularis and zona fasciculata but not the zona glomerulosa were positive, whereas in the adrenal medulla viral nucleic acid was predominantly localized to adrenalin-secreting cells. Infection of the renal tubules, transitional epithelium of the bladder and the ducts of the salivary gland indicates the likely sites of virus production for the dissemination of arenavirus infections.

Abstract
The systemic distribution of Epstein-Barr virus (EBV) genomes was studied in paraffin-embedded tissues from 12 fatal cases of Post-transplantation lymphoproliferative disease (PTLD), using an in situ hybridization technique employing an alpha-35S-dCTP-radiolabeled BamHI-W fragment of EBV DNA. The presence of EBV was documented in various PTLD-involved organs. The hybridization signal for the virus localized predominantly in the abnormal lymphoid cells, but signals also were detected in hepatocytes and/or adrenal cortical cells in five cases. The distribution of autoradiographic label within the lymphoid cells was focal and its intensity varied from field to field suggesting a nonuniformity of the viral genomic load in the infected tissues. Recruitment of EBV genome-bearing cells was not observed into inflammatory mononuclear infiltrates found in organs without histopathologic evidence of PTLD.

Abstract
The influence of genetic properties of parts of the HSV-1 genome on suppression of humoral antibody formation was investigated by using intratypic recombinants. The deleted strain HFEM (HSV-1) induces suppression. The MluI DNA fragment (coordinates 0.7615-0.796 m.u.) derived from the antibody inducing strain F1 (HSV-1) was transfected into the deleted strain HFEM to produce the recombinant virus R-M1CI and shown to restore antibody formation, as demonstrated by neutralization- and ELISA-tests. The intratypic recombinant viruses R-15, R-19 and R-26, produced by transfection of the Bam HI DNA-fragment B (0.738-0.809 m.u.) of strain F1 into the deleted strain HFEM, resulted in antibody formation only in the recombinant virus R-26. The reason for these different properties might be associated with the presence of small deletions in the SmaI A-fragment (0.763-0.765 m.u.) or elsewhere in the Bam HI DNA-fragment B. Our results were finally correlated to replication of the recombinant viruses in macrophages and to spread into spleen and adrenal glands. There is evidence that antibody formation may be correlated to the ability of HSV to replicate in macrophages.

Abstract
HSV-2 strain ER was shown to consist of variants with different pathogenic phenotype: Variant ER+ replicates to high titers in the adrenal glands and the ovaries but much less in the spleen; the testes were not colonized. ER+ migrates to the spinal ganglia and is highly neuroinvasive after i.p. inoculation. Variant ER- replicates 100-1,000 fold less in the adrenal glands and the ovaries, but proceeds to the spinal ganglia without invading the CNS. However, both variants are highly neuropathogenic after direct i.c. injection. We conclude that neuropathogenicity, neuroinvasiveness and the ability to replicate in the adrenal glands as well as ovaries are each determined by different sets of genes. Replication in mouse embryo fibroblasts--but not in Vero and adreno cortical carcinoma Y1 cells--is different for both strains. Also the adsorption capacity to cultured cells differs as shown by addition of D.S. 500. ER- is eliminated from the blood stream more quickly than ER+. Finally, C. parvum reduces the rate of replication of both variants in the adrenal and the ovaries. It is concluded that different adsorption and replications rates of variants ER+ and ER- in cell types critical for spread of HSV are responsible for the different pathobiological properties.
