Abstract/ Executive Summary:

Dhaka Zoo with 2000 animals of 184 species and five million visitors a year is important from a public health point of view. This study was conducted to investigate coccidioidomycosis in captive animals at Dhaka Zoo. One hundred and two tissue samples were collected and preserved in 10% neutral buffered formalin at necropsy of 36 animals of 25 species. Twenty five animals were suffering from granulomatous diseases, of which ten were identified as coccidioidomycosis. Clinical history, nodular lesions at necropsy, granulomatous lesions on histopathology and characteristic spores on special staining confirmed coccidioidomycosis in six rhesus macaques (Macaca mulatta), one horse (Equus caballus), one common langur (Presbytis entellus), one beisa oryx (Oryx beisa beisa) and one reticulated python (Python molurus). It is suggested that coccidioidomycosis in captive animals threatens human and animal health.

Objectives:

1. To investigate the prevalence of coccidioidomycosis and the clinico-pathological changes in animals at Dhaka Zoo.

Methodology:

A total of 102 formalin-fixed tissue specimens from 36 zoo animals of 25 species were obtained at necropsy and examined histopathologically. The study included eight rhesus macaques (Macaca mulatta), four spotted deer (Cervus axis/Axis axis), two sambar deer (Cervus unicolor), and two golden pheasant (Chrysolophus pictus). Samples were also taken from guinea pig (Cavia porcellus), wildebeest (Connochaetes taurinus), striped hyena (Hyena hyena), Indian/ Asiatic lion (Panthera leo persica), gayal (Bos frontalis), American rhea (Rhea americana), Australian terrier dog (Canis lupus familiarizes), zebra (Equus zebra hartmannae), nilgai (Boselaphus tragocamelus), horse (Equus caballus), barking deer (Muntiacus muntjak), ostrich (Struthio camelus), crested serpent-eagle (Spilorins cheela), common langur (Presbytis entellus), fishing cat (Felis viverrina), beisa oryx (Oryx beisa beisa), reticulated python (Python molurus), water buck (Kobus L. leche), greater kudu (Tragelaphus strepsiceros), and olive baboon (Papio anubis). The animals could be classified as non-human primates (n = 10), carnivores (n = 4), herbivores (n = 16), reptiles (n = 1) and birds (n = 5). Recorded clinical history before necropsy was collected from the Zoo register. At necropsy, tissue changes were photographed and lesions tissues were preserved in 10% neutral buffered formalin. Formalin-fixed samples were processed for paraffin embedding, sectioning and staining with routine haematoxylin and eosin staining, periodic acid Schiff (PAS) for fungus. Photomicrograph was taken using Olympus PM-C 35 camera and Digital Camera Mounted Photomicrographic device (Differential Interference Contrast–DIC; Olympus, Nizol FC, E-5000, 8.4V, 0.9A, CE N 150).

Achievement/Findings:

Coccidioides organism possesses serious public health consequences and therefore, prevention and control of this disease in Dhaka zoo is necessary to improve public health. However, further studies should be focused on typing and molecular characterization of coccidioidomycosis.
