A recent study has revealed the occurrence of tuberculosis (TB) infections caused by Mycobacterium pinnipedii in multiple exotic animal species living in two separate zoological gardens over a span of five years. The affected animals include a South American sea lion, a Bactrian camel, and several Malayan tapirs. The investigation highlights the complex epidemiological connections within and between zoological collections, noting that the zoos involved were linked by the transfer of at least one Malayan tapir.
Mycobacterium pinnipedii is a member of the Mycobacterium tuberculosis complex (MTBC), which is more commonly associated with marine mammals but has occasionally been found in other animal species. In this instance, specialized bacteriological cultures and molecular diagnostics confirmed the presence of M. pinnipedii in all the affected animals. The temporal and spatial spread of the cases underscore the challenges of managing infectious diseases in diverse captive animal populations.
Detailed genetic analysis and contact tracing were employed to evaluate the epidemiological links between the cases. The findings suggest that disease transmission may have occurred either through shared environments or animal transfers. The movements and health histories of all affected animals were scrutinized to piece together potential transmission pathways.
The report stresses the importance of early detection and stringent biosecurity measures in managing TB infections in zoos. Routine health monitoring, quick isolation of symptomatic animals, and inter-institutional cooperation during animal exchanges are critical in preventing outbreaks of this kind.
This case series also adds to the growing body of literature on emerging zoonotic threats and the role of wildlife and exotic animals in the epidemiology of TB. Further research is encouraged to understand the reservoirs and transmission dynamics of M. pinnipedii in non-marine species.
The study illustrates the need for continued vigilance and investment in veterinary public health infrastructure within zoological institutions to prevent and control infectious diseases that pose risks to both animal and human health.
