Measles in monkeys: an epidemiological study.

Area of Science:

• Veterinary Virology
• Primate Immunology
• Zoonotic Diseases

Background:

• Measles virus is a significant pathogen in non-human primates.
• Understanding measles transmission and pathogenesis in primates is crucial for conservation and public health.
• Imported primates can pose a risk for disease introduction into naive populations.

Purpose of the Study:

• To investigate measles infection dynamics in captive non-human primates.
• To assess the impact of importation on measles immunity in primate populations.
• To explore the clinical and pathological manifestations of measles in monkeys.

Main Methods:

• Monitoring antibody titers in imported and captive monkeys.
• Observing clinical signs and outcomes of measles infection.
• Histopathological examination of tissues from fatal cases.

Main Results:

• Imported monkeys with high antibody titers showed slow antibody decline in captivity.
• Infected monkeys produced non-immune offspring.
• An outbreak included symptomless infections, contrasting with measles' usual fatality in monkeys.
• Histology revealed measles virus infection in the urinary bladder wall of one monkey.

Conclusions:

• Measles in non-human primates shares close similarities with human measles.
• Primate measles studies offer valuable insights into human measles pathogenesis and control.
• The potential for symptomless infections and transmission in primates warrants further investigation.
