Assistant Laboratory Animal Technician (ALAT) Practice Exam

Which virus is specifically associated with Old World macaque monkeys?

1. B virus

2. Ebola virus

3. HIV

4. SARS-CoV

The correct answer is: B virus

The B virus, also known as Cercopithecine herpesvirus 1, is specifically associated with Old World macaque monkeys. This virus is particularly concerning in laboratory settings because it can be transmitted to humans and may cause severe neurological disease or even be fatal if not handled properly. Understanding the B virus’s association with Old World primates is crucial for laboratory animal technicians, as it informs safety protocols and risk assessments when working with these animals. In contrast, other viruses listed have broader geographic and species ranges. The Ebola virus, while serious, is linked to several species of fruit bats and monkeys but is not specifically associated with Old World macaques. Similarly, HIV is primarily associated with humans and has origins in certain primate species but again is not limited to Old World macaque monkeys. SARS-CoV, which leads to COVID-19, primarily involves other species, including bats and pangolins, and is not specifically tied to Old World macaques. Understanding these associations is essential for effective animal care and research safety in facilities that utilize these species.
