“…Fatal toxoplasmosis was diagnosed in a captive, adult female saiga antelope (Saiga tatarica). T. gondii was detected in the liver, lung, spleen, kidney, and intestine and confirmed by PCR (Sedlak et al, 2004). Acute toxoplasmois has been seen in captive Cuvier's gazelle (Gazella cuvieri), slender-horned gazelle (Gazella leptoceros), dama gazelle (Gazella dama), and gerenuk (Litocranius walleri) housed in North American Zoos (Stover et al, 1990;Junge et al, 1992).…”

“…Abortion and neonatal death have been observed in captive nilgais (Boselaphus tragocamelus). T. gondii DNA was demonstrated in the tissues of the nilgais using PCR (Sedlak et al, 2004). Fatal toxoplasmosis was diagnosed in a captive, adult female saiga antelope (Saiga tatarica).…”

Toxoplasma gondii is widely distributed in wild and domestic animals. The present chapter reviews toxoplasmosis in wild and domestic animals. Coverage in wild animal species is limited to confirmed cases of toxoplasmosis, cases with parasite isolation, cases with parasite detection by polymerase chain reaction (PCR), and experimental infection studies (Figs. 6.1À6.3). Studies concerning serological prevalence have not been included for the majority of host species. This was done because many serological tests, e.g. latex agglutination (LAT), indirect fluorescent antibody (IFAT), and indirect hemagglutination), have been demonstrated to underestimate the prevalence of T. gondii. Toxoplasmosis in wildlife 6.2.1 FelidsCongenital toxoplasmosis has been reported in bobcats (Felis rufus) kits (Dubey et al., 1987). Toxoplasmic meningoencephalitis has been observed in a 6-month-old bobcat . T. gondii has been isolated from the tissues of adult bobcats (Lindsay et al., 1997b;Dubey et al., 2004b). Bobcats are important in maintaining T. gondii in wild herbivores in many areas of the United States (Fig. 6.1). Oocysts excreted by cougars (Felis concolor) were thought to be the source of a large water borne outbreak of human toxoplasmosis in Victoria,

Abstract. A 6-year-old, male southern chamois (Rupicapra pyrenaica) had an absence of flight response and was captured by hand in the Catalan Pyrenees in northeast Spain. On clinical examination, the animal was in good body condition, and only atrophy of the right eye was observed. Blood samples were collected and hematologic analysis performed, but no alterations were observed. The animal was sent to a Wildlife Rescue Centre, where it developed chronic wasting and died after 32 days in captivity. At necropsy, the animal was cachectic and had edematous, mottled lungs. Histopathologic examination revealed systemic toxoplasmosis and acute Gram-negative septicemia. The protozoan organisms were identified as Toxoplasma gondii based on immunohistochemistry. An indirect fluorescent antibody test was performed, and the animal was positive with an antibody titer of 1:50.
