B Virus Infection Is Caused By The Zoonotic Agent Macacine Herpesvirus 1

B virus infection is caused by the zoonotic agent Macacine herpesvirus 1 1

B virus infection is caused by the zoonotic agent Macacine herpesvirus 1, an alphaherpesvirus commonly found among macaque monkeys the natural host. B Virus (herpes B, monkey B virus, herpesvirus simiae, and herpesvirus B). B virus infection is caused by the zoonotic agent Macacine herpesvirus 1. However, zoonotic infection with B virus in humans usually results in fatal encephalomyelitis or severe neurologic impairment.

B virus infection is caused by the zoonotic agent Macacine herpesvirus 1 2Conversely, when humans are zoonotically infected with B virus, patients can present with severe central nervous system disease, resulting in permanent neurological dysfunction or death. B virus is the only identified nonhuman primate herpesvirus that displays severe pathogenicity in humans. By 1959, B virus was identified as the causative agent in 17 human cases, 12 of which resulted in death. Serious disease due to BV is rare in macaques, but when transmitted to humans, BV has a propensity to invade the central nervous system and has a fatality rate greater than 70 if not treated promptly. However, the fatal effect of zoonotic BV infection in humans has driven the effort to eliminate BV from research macaques. In some, but not all, cases of zoonotic B virus infection, acyclovir and ganciclovir have proven to be effective at curtailing disease progression (7, 8).

B virus (Cercopithecine herpesvirus 1) is a zoonotic agent that can cause fatal encephalomyelitis in humans. Previously reported cases of B virus disease in humans usually have been attributed to animal bites, scratches, or percutaneous inoculation with infected materials; however, the first fatal case of B virus infection due to mucosal splash exposure was reported in 1998. B virus (Macacine herpesvirus 1) is closely related to herpes simplex virus 1 (HSV-1) and encodes gD, which shares more than 70 amino acid similarity with HSV-1 gD. B virus is the only known simplexvirus that causes zoonotic infection, resulting in approximately 80 mortality in untreated humans or in lifelong persistence with the constant threat of reactivation in survivors. During these investigations, B virus was categorized as a select agent by the Department of Homeland Security (DHS); thus, all experiments were done in accordance with relevant Health and Human Services (HHS) (64, 65) and DHS regulations in the Viral Immunology Center biosafety level 3 (BSL-3) laboratory of Georgia State University prior to 2007 and BSL-4 laboratory following that date. Cercopithecine herpesvirus 1 (B virus), enzootic among monkeys of the genus Macaca, causes minimal morbidity in its natural host. However, cases of severe zoonotic disease, including infections with Macacine herpesvirus 1 (Herpes B) and Marburg-Reston virus, led to the implementation of stricter guidelines governing contact with NHP B Virus Working Group, 1988;Holmes et al. We conclude that primatologists are at high risk for exposure to NHP-borne infectious agents.

Herpes B Virus

B virus infection is caused by the zoonotic agent Macacine herpesvirus 1 3Organism or Agent: Macacine herpes virus 1 (MHV-1). Zoonosis: Yes, through direct or indirect contact with the bodily fluids of MHV-1 infected monkeys. The vesicular eruption is clinically and pathologically similar to that caused by herpes simplex virus. Though it rarely causes disease in the natural host, accidental infection in humans and nonmacaque primates have been reported to cause fatal disseminated infection. The clinical course of disseminated viral infection can be peracute to slowly progressive, and herpes B virus infection as an underlying causative agent may not be suspected. Herpes B virus infection of humans is characterized by ascending paralysis and a high mortality rate. This resulted in early removal of all high-dose monkeys from the study because of zoonotic concerns.

Human Herpes Virus Type 6 (HHV-6) Is The Causative Agent Of Kaposi’s Sarcoma

Kaposi’s sarcoma-associated herpesvirus (KSHV) is the eighth human herpesvirus; its formal name according to the International Committee on Taxonomy of Viruses (ICTV) is HHV-8. The discovery of this herpesvirus sparked considerable controversy and scientific in-fighting until sufficient data had been collected to show that indeed KSHV was the causative agent of Kaposi’s sarcoma. Human herpesvirus 8 (HHV-8) sequences were detected for the first time in Kaposi sarcoma specimens (92,93) by representational difference analysis PCR; HHV-8 is being investigated as the possible etiologic agent.

Human herpes viruses type 6 and 7; causative agents of, among others, exanthema subitum. Eight or more herpes virus types are known to infect man frequently (table 1 and 2, figure 1). Direct repeats do not allow recombination and so EBV and HHV6 have only one isoform. Kaposi sarcoma is caused by human herpesvirus 8, an infection most likely to become problematic in people with compromised immune systems. It originates in the endothelial cells which line blood vessels and lymphatic vessels, causing these to grow at a faster rate and to survive for longer than normal. 1950s) that an infectious agent was the cause of Kaposi sarcoma, it was only in the wake of the HIV/AIDS epidemic that this theory was seriously explored. The Kaposi sarcoma-associated herpesvirus is the eighth and most recently discovered type of herpesvirus.5,6.

Human Herpesvirus 6

Several investigators have suggested that HHV-6, a beta herpesvirus, also may be an oncogenic virus, as cells transfected with HHV-6 have been shown to cause tumors in nude mice (Puri 1991). However, the evidence linking HHV-6 to human malignancies is far from definitive. Torelli et al reported finding HHV-6 sequences by PCR in 3/25 cases of Hodgkin’s disease, all nodular sclerosis type, and in none of 41 cases of non-Hodgkin’s lymphoma (Torelli 1991). (Gomez-Roman 2009), HHV-6 was reported as the only viral agent present in two cases of adenocarcinomas. Human herpesvirus 8 (HHV-8), also known as Kaposi’s sarcoma-associated herpesvirus (KSHV), discovered in 1994, is a human rhadinovirus (gamma-2 herpesvirus). Article: Quantification of viral genome in cord blood donors by Real Time PCR to investigate human herpesvirus type 8 active infection. Human herpes virus type 6 (HHV-6) is the causative agent of Kaposi’s sarcoma. For patients with visceral Kaposi’s sarcoma, bleomycin combined with vincristine is the treatment of choice. In adults, primary infection with HHV-6 can produce a mononucleosis-like illness and, more rarely, severe disease, including encephalitis. Kaposi’s sarcoma in persons with.

The Main Causative Agent Of Shingles Is The Virus Known As Herpes Zoster

Shingles, also known as zoster, herpes zoster, or zona, is a viral disease characterized by a painful skin rash with blisters involving a limited area. The causative agent for shingles is the varicella zoster virus (VZV)a double-stranded DNA virus related to the Herpes simplex virus. Chickenpox is a highly contagious, but usually mild, disease. The causative agent is called human herpesvirus 3 (HHV-3) or varicella zoster virus (VZV).

The main causative agent of Shingles is the virus known as herpes zoster 2Herpes zoster (HZ), commonly called shingles, is a distinctive syndrome caused by reactivation of varicella zoster virus (VZV). As cellular immunity to VZV decreases with age or because of immunosuppression, the virus reactivates and travels along the sensory nerves to the skin, causing the distinctive prodromal pain followed by eruption of the rash. 14,15 Corticosteroids are associated with a considerable number of adverse effects and hence should be used only in patients with severe symptoms at presentation or in whom no major contraindications to corticosteroids exist.

This virus is the causative agent of chicken pox, a disease characterized by a blister-like rash on the skin and often accompanied by fever. After recovering from the varicella disease, a person may develop shingles, also known as zoster or herpes zoster, due to the virus remaining in the dorsal root ganglia.
