Comprehensive Diagnosis, Treatment, and Outcome of Cysticercosis in a Ring-Tailed Lemur () from a Croatian Zoo: No Longer Unusual?

is a zoonotic tapeworm of the genus that is distributed throughout the Northern Hemisphere. Wild and domestic carnivores are final hosts, while rodents and rabbits are primarily intermediate hosts, although many other mammals may harbour the larval stage, . This case report aims to describe infection in a lemur and molecularly characterise the isolated parasite.

Clinical and histopathological investigation of symmetrical alopecia with associated chronic pruritus in tufted capuchin monkeys (Sapajus apella apella).

Background: Symmetrical alopecia is a common symptom of endocrine and autoimmune diseases, which are rarely manifested with pruritus. Increased levels of stress in primates have been presented with increased levels of pruritus and alopecia appearance.

Methods: A pruritic and alopecic disease was investigated in a group of tufted capuchin monkeys (N = 12), but due to ethical reasons, four random animals were further investigated by numerous diagnostic methods.

Investigating the Presence of SARS CoV-2 in Free-Living and Captive Animals.

Due to SARS CoV-2 recombination rates, number of infected people and recent reports of environmental contamination, the possibility of SARS CoV-2 transmission to animals can be expected. We tested samples of dominant free-living and captive wildlife species in Croatia for the presence of anti-SARS CoV-2 antibodies and viral RNA. In total, from June 2020 until February 2021, we tested blood, muscle extract and fecal samples of 422 free-living wild boars (), red foxes () and jackals (); blood and cloacal swabs of 111 yellow-legged gulls () and fecal samples of 32 zoo animals.

Eccrine carcinoma in the foot of an Asian elephant (Elephas maximus).

A case of eccrine carcinoma of the interdigital foot glands in a 39-yr-old female Asian elephant (Elephas maximus) from Zagreb Zoo is described. The tumor between the toenails of the right forefoot was surgically removed 3 yr before postmortem examination (2003), and the histopathologic diagnosis was compound eccrine carcinoma characterized with glandular tubular and papillary proliferations, mild cellular pleomorphism, proliferation of the myoepithelial cells with mucoid secretions, and necrosis. Immunohistochemistry revealed strong immunoreactivity to S-100 protein, estrogen, and high-molecular weight cytokeratin.

Prevalence and molecular typing of Giardia spp. in captive mammals at the zoo of Zagreb, Croatia.

A total of 131 faecal samples from 57 mammalian species housed at the zoo of Zagreb, Croatia, were tested for the presence of Giardia spp. cysts using epifluorescence microscopy. The overall prevalence (29%) was high, yet all animals were asymptomatic at the time of sampling.

Disseminated tuberculosis in hyrax (Procavia capensis) caused by Mycobacterium africanum.

Tuberculosis due to Mycobacterium africanum was diagnosed in an adult female hyrax (Procavia capensis). Pathologic examination revealed disseminated tuberculous lesions. The same pathologic changes were also found in a male hyrax that died a year later.

Yersiniosis in zoo marmosets (Callitrix jacchuss) caused by Yersinia enterocolitica 4/O:3.

The aim of this research was to describe two fatal cases of Yersinia enterocolitica bioserotype 4/O:3 infection in non-human primates and to characterise the isolates by PCR and PFGE. In July 2004, two marmosets (Callitrix jacchuss) born in captivity in Zagreb Zoo, died following a few days of intermittent diarrhoea in intervals of 2 weeks. The pathomorphological diagnosis of the female (born in 1997) and the male (born in 1995) marmoset, was disseminated miliary necrosis of the liver.
