Abstract
B virus is a herpes virus that natutaly infects macaque monkeys. It is extremely neuropathogenic when infection occurs in humans. B virus infection has been reported only in laboratory workers and breeders of macaque monkeys in North America and the United Kingdom, and it is therefore recognized as a rare infectious disease. The first cases of B virus disease were reported in Japan in 2019 and in China in 2021, although no cases had been reported since 1997. Although B virus disease has not been reported for more than 20 years, the potential threat has always existed. The viral factors responsible for the strong neuropathogenicity of B virus to humans has not been identified. There are no reports of infection by contact with wild macaque monkeys, but the possibility can not been ruled out. In this paper, we describe its virological properties, findings from B virus disease from patient-reported cases, and the genotype of B virus.

Abstract
Though rare due to measures and practices to control the risk, infections can occur in research and toxicology studies, especially in nonhuman primates (NHPs) exposed to xenobiotics, particularly immunomodulatory drugs. With such xenobiotics, immunocompromised or immunosuppressed animals will not be able to mount a protective response to infection by an opportunistic pathogen (bacteria, virus, parasite, or fungus) that might otherwise be nonpathogenic and remain clinically asymptomatic in immunocompetent animals. The respiratory tract is one of the most commonly affected systems in clinic, but also in toxicology studies. Pulmonary inflammation will be the main finding associated with opportunistic infections and may cause overt clinical disease with even early sacrifice or death, and may compromise or complicate the pathology evaluation. It is important to properly differentiate the various features of infection, to be aware of the range of possible opportunistic pathogens and how they may impact the interpretation of pathology findings. This review will present the most common bacterial, viral, parasitic, and fungal infections observed in the respiratory tract in NHPs during research and/or toxicology studies.

LONG-TERM SURVEILLANCE OF LANGUR ALPHAHERPESVIRUS IN A ZOO POPULATION OF SILVERED LANGURS ( TRACHYPITHECUS CRISTATUS). J Zoo Wildl Med 2018; 49:345-354.

Abstract
Langur alphaherpesvirus (HVL), a provisionally named alphaherpesvirus in the Simplexvirus genus, was first identified in 1991 at the Bronx Zoo in wild-origin silvered langurs ( Trachypithecus cristatus) and their descendants. HVL is closely related to B virus ( Macacine alphaherpesvirus 1) based on serologic and genetic data, but its natural history and zoonotic potential remain unknown. A cohort study was undertaken to describe the epidemiology, clinical impact, and potential management implications of this virus in a naturally infected, zoo-based population of silvered langurs. Opportunistic surveillance sampling from 1991 through 2015 resulted in 235 serum samples and 225 mucosal swabs from 75 individuals. A total of 43 individuals (57.3%) were seropositive for HVL within this period. Seroprevalence increased significantly with age, and indirect evidence suggested a peak in transmission at the onset of sexual maturity. These findings were similar to the behavior of other simplexviruses in their adapted hosts. Yearly cumulative incidence declined significantly through the study period, with zero or one new case detected each year from 2007 through 2015. The density of this population decreased within the study period for management reasons unrelated to HVL infection, and a change in age distribution or less-frequent contacts may have contributed to low transmission. In addition, clinical signs of simplexvirus infection were rare, and virus isolation was negative on all mucosal swabs, suggesting that viral shedding was infrequent. Yearly period seroprevalence remained relatively constant with a median of 45.8%, likely because of the extended survival of infected individuals within the population. Maintenance of a naturally occurring, novel virus with unknown zoonotic potential in a zoo population for over 25 yr highlights the importance of biosecurity and biosafety for management of silvered langurs and all primate species.

Abstract
Complete genome sequences of 19 strains of monkey B virus (Macacine alphaherpesvirus 1; BV) isolated from several macaque species were determined. A low level of sequence variation was present among BV isolates from rhesus macaques. Most variation among BV strains isolated from rhesus macaques was located in regions of repetitive or quasi-repetitive sequence. Variation in coding sequences (polypeptides and miRNAs) was minor compared to regions of non-coding sequences. Non-coding sequences in the long and short repeat regions of the genome did however exhibit islands of conserved sequence. Oral and genital isolates from a single monkey were identical in sequence and varied only in the number of iterations of repeat units in several areas of repeats. Sequence variation between BV isolates from different macaque species (different BV genotypes) was much greater and was spread across the entire genome, confirming the existence of different genotypes of BV in different macaque species.

Abstract
Herpes B virus (BV, Macacine alphaherpesvirus 1) infects macaques asymptomatically, with rare exceptions, but can cause fatal encephalitis in humans. Here, we report disseminated BV infection in a cynomolgus macaque that had died within 12 hour after the onset of unspecific symptoms. Multifocal lesions surrounded by viral antigen were detected in liver while other organs remained inconspicuous, indicating that the liver is a major target. Moreover, high copy numbers of viral DNA were found in feces, underlining the excrements are a potential source of transmission.

Abstract
Herpes B virus (BV) infection is highly prevalent among adult Asian macaques
and rarely causes severe disease in infected animals. In contrast, BV
infection of humans can induce fatal encephalitis in the absence of
treatment. Therefore, the development of diagnostic tests for specific and
sensitive detection of antibodies against BV is an important task. The
cross-reactivity of antibodies against BV with related simplex viruses of
other primates may afford an opportunity to obtain sensitive detection
systems without the need to work with the highly pathogenic BV. Moreover, it
has been proposed that use of recombinant viral glycoproteins may allow for a
detection of antibody responses against BV with high specificity. However,
limited data are available for both approaches to BV diagnostic. Here, we
report that simian agent 8 (SA8; infects African green monkeys)- and
herpesvirus papio 2 (HVP-2; infects baboons)-infected cells allow for a more
sensitive detection of antibody responses against BV in macaques than lysates
of herpes simplex virus type 1 and 2 (HSV-1/2;
infect humans)-infected cells and a
commercial HSV ELISA (Enzygnost®
Anti-HSV/IgG). In addition, we show that sera from BV-infected macaques
frequently contain antibodies against the recombinant BV glycoprotein gD (BV
gD) that has been previously proposed as a diagnostic target for
discriminating BV- and HSV-induced antibodies. However, we found that
antibodies of some HSV-infected human patients also reacted with BV gD. In
contrast, only sera of HSV-1- and HSV-2-infected humans, but not sera from
BV-infected macaques, reacted with HSV-1/2 gG. Collectively, these results
suggest that both SA8 and HVP-2 allow for sensitive and comparable detection
of BV-directed antibody responses in macaques and that the combination of BV
gD and HSV-1/2 gG needs to be complemented by a least one additional viral
glycoprotein for reliable discrimination between antibody responses against
BV and HSV-1/2 in humans.

Abstract
Specific pathogen free (SPF) macaques provide valuable animal models for biomedical research. In 1989, the National Center for Research Resources [now Office of Research Infrastructure Programs (ORIP)] of the National Institutes of Health initiated experimental research contracts to establish and maintain SPF colonies. The derivation and maintenance of SPF macaque colonies is a complex undertaking requiring knowledge of the biology of the agents for exclusion and normal physiology and behavior of macaques, application of the latest diagnostic technology, facilitiy management, and animal husbandry. This review provides information on the biology of the four viral agents targeted for exclusion in ORIP SPF macaque colonies, describes current state-of-the-art viral diagnostic algorithms, presents data from proficiency testing of diagnostic assays between laboratories at institutions participating in the ORIP SPF program, and outlines management strategies for maintaining the integrity of SPF colonies using results of diagnostic testing as a guide to decision making.

Abstract
A 2-year-old, female, simian immunodeficiency virus E543-infected rhesus macaque (Macaca mulatta) was presented for necropsy following euthanasia due to a history of diarrhea, weight loss, and a small, round ulcer along the left labial commissure. Histopathologic examination of the ulcer revealed infiltration by large numbers of degenerate and nondegenerate neutrophils and macrophages admixed with syncytial epithelial cells. Rare epithelial cells contained herpetic inclusion bodies. These cells stained positive for Human herpesvirus 1 via immunohistochemistry, and DNA sequencing confirmed the presence of closely related Macacine herpesvirus 1 (B virus).

Abstract
Cocaine use during pregnancy is deleterious to the newborn child, in part via its disruption of placental blood flow. However, the extent to which cocaine can affect the function of the fetal primate brain is still an unresolved question. Here we used PET and MRI and show that in third-trimester pregnant nonhuman primates, cocaine at doses typically used by drug abusers significantly increased brain glucose metabolism to the same extent in the mother as in the fetus (approximately 100%). Inasmuch as brain glucose metabolism is a sensitive marker of brain function, the current findings provide evidence that cocaine use by a pregnant mother will also affect the function of the fetal brain. We are also unique in showing that cocaine's effects in brain glucose metabolism differed in pregnant (increased) and nonpregnant (decreased) animals, which suggests that the psychoactive effects of cocaine are influenced by the state of pregnancy. Our findings have clinical implications because they imply that the adverse effects of prenatal cocaine exposure to the newborn child include not only cocaine's deleterious effects to the placental circulation, but also cocaine's direct pharmacological effect to the developing fetal brain.
