[Prevalence of laboratory markers of human respiratory viruses in monkeys of Adler primate center].

Introduction: The relevance of studying the circulation of human respiratory viruses among laboratory primates is associated with the need to test vaccines and antiviral drugs against these infections on monkeys.The aim of this work was to study the prevalence of serological and molecular markers of human respiratory viral infections in laboratory primates born at the Adler Primate Center and in imported monkeys.

Material And Methods: Blood serum samples (n = 1971) and lung autopsy material (n = 26) were obtained from different monkey species.

[Markers of viral hepatitis E (Hepeviridae, Orthohepevirus, Orthohepevirus A) in the imported Old World monkeys].

Introduction: Viral hepatitis E is a zooanthroponotic disease that occurs in humans and various animals, including monkeys. It is caused by hepatitis E virus (HEV) (Hepeviridae, Orthohepevirus: Orthohepevirus A), for which 8 genotypes have been described to date. Among them, strains of genotypes 1 and 2 have been isolated from humans, strains of genotypes 3 and 4 from humans and animals, and strains of genotypes 5-8 from animals only.

Natural infection of captive cynomolgus monkeys (Macaca fascicularis) with hepatitis E virus genotype 4.

Data on natural HEV infection of infection in monkeys are limited. We report a case of hepatitis E virus genotype 4 infection in captive non-human primates (cynomolgus monkeys) imported from Vietnam. Phylogenetic analysis demonstrated that HEV infection was not the result of spillover from single source of infection, but rather the persistent circulation of HEV-4 among cynomolgus monkeys or multiple infections by related strains from a human or swine reservoir.

[Markers of hepatitis A in the monkeys of the Adlers primate center.].

Unlabelled: Hepatitis A is a widespread viral infection. The HAV strains of "human" and "monkey" origin are similar in their morphological and antigenic properties, but differ genotypically.

Objectives: The aim of this research was a comparative study of serological and molecular-genetic markers of HAV infection in monkeys born at the Adler Primate Center and in those imported from different countries.

Molecular genetic identification of isolates of the hepatitis A virus (HAV) from monkeys at Adler Primate Center.

Background: The aim of this study was to assess prevalence and genetic variability of hepatitis A virus (HAV) isolates in monkeys born and kept at Adler Primate Center, as well as in imported animals.

Methods: The fecal samples from various species of monkeys (n = 119) were studied using reverse transcription seminested PCR, sequencing, and phylogenetic analysis.

Results: HAV RNA was detected in 2 Macaca mulatta and 1 Macaca fascicularis (3.
