“…They found 13% and 75% positivity, respectively, for the deer that live inside the park and the ones from Pantanal, which is close to farms indicating that this proximity of wild and domestic animals could increase the occurrence of N. caninum infection among deer. From the Zoo of Curitiba, PR, 17 samples from Barbary sheep (Ammotragus lervia), from the Bovidae Family, were examined and four (23.5%) presented N. caninum antibodies (MORIKAWA et al, 2014). Yai et al (2003) tested 396 feral opossums (Didelphis marsupialis) samples from different regions of the city of São Paulo, and 21.2% (84/396) were positive.…”

Neospora caninum is protozoan parasite with domestic and wild dogs, coyotes and grey wolves as the definitive hosts and many warm-blooded animals as intermediate hosts. It was cultivated and named in 1988. Neosporosis is a major disease of cattle and has no public health significance. Since 1990's N. caninum has emerged as a major cause of abortion in cattle worldwide, including in Brazil. N. caninum also causes clinical infections in several other animal species. Considerable progress has been made in understanding the biology of N. caninum and there are more than 200 papers on this subject from Brazil. However, most of the reports on neosporosis from Brazil are serological surveys. Overall, little is known of clinical neosporosis in Brazil, particularly cattle. The few reports pertain to sporadic cases of abortion with no information on epidemics or storms of abortion. The objective of the present review is to summarize all reports from Brazil and suggest topic for further research, including prevalence of N. caninum oocysts in soil or in canine feces, and determining if there are additional definitive hosts, other than the domestic dog. There is need for a national survey in cattle using defined parameters. Future researches should focus on molecular characterization of N. caninum strains, possibility of vaccine production and relationship between wildlife and livestock epidemiology.Keywords: Neospora caninum, neosporosis, domestic animals, wild animals, Brazil. ResumoNeospora caninum é um protozoário parasita que possui os canídeos domésticos e selvagens, coiotes e lobos cinzentos como hospedeiros definitivos e vários animais de sangue quente como hospedeiros intermediários. Foi cultivado e nomeado em 1988. A neosporose é uma das principais doenças em bovinos e não tem significância em saúde pública. Desde 1990, N. caninum tem emergido como uma das principais causas de aborto em bovinos em todo o mundo, inclusive no Brasil. N. caninum também causa infecções clínicas em várias outras espécies animais. Consideráveis avanços foram feitos na compreensão da biologia desse parasita e há mais de 200 trabalhos sobre o assunto no Brasil. No entanto, a maioria dos relatos de neosporose do Brasil são relacionados a sorologia. Em geral, pouco se sabe sobre a neosporose clínica no Brasil, particularmente em bovinos. Os poucos relatos referem-se a casos esporádicos de aborto sem informações sobre epidemias ou surtos de aborto. O objetivo da presente revisão é resumir todos os relatos sobre N. caninum no Brasil e sugerir tópicos para pesquisas futuras, incluindo a prevalência de oocistos de N. caninum no solo ou em fezes caninas e determinar se há hospedeiros definitivos adicionais, exceto o cão doméstico no país. Uma pesquisa nacional em bovinos usando parâmetros definidos seria de grande importância. Pesquisas futuras deveriam ser focadas na caracterização de cepas de N. caninum, possibilidade de produção de vacinas e a relação epidemiológica entre a vida selvagem e o gado.Palavras-chave: Neospora caninum, neospo...

The purpose of this study was to describe the normal ocular anatomy and establish reference values for ophthalmic tests in the Barbary sheep or aoudad (Ammotragus lervia). Aoudad eyes are large and laterally positioned in the head with several specialized anatomic features attributed to evolutionary adaptations for grazing. Normal values for commonly used ophthalmic tests were established, Schirmer tear test (STT) - 27.22 ± 3.6 mm/min; Predominant ocular surface bacterial microbiota - Staphylococcus sp.; Corneal esthesiometry- 1.3 ± 0.4 cm; Intraocular pressure by rebound tonometry- 19.47 ± 3.9 mmHg; Corneal thickness- 630.07 ± 20.67 µm, B-mode ultrasonography of the globe-axial eye globe length 29.94 ± 0.96 mm, anterior chamber depth 5.03 ± 0.17 mm, lens thickness 9.4 ± 0.33 mm, vitreous chamber depth 14.1 ± 0.53 mm; Corneal diameter-horizontal corneal diameter 25.05 ± 2.18 mm, vertical corneal diameter 17.95 ± 1.68 mm; Horizontal palpebral fissure length- 34.8 ± 3.12 mm. Knowledge of these normal anatomic variations, biometric findings and normal parameters for ocular diagnostic tests may assist veterinary ophthalmologists in the diagnosis of ocular diseases in this and other similar species.

Aim:This study is part of an active surveillance program for monitoring animal health status in endangered species, and was conducted to screen captive Barbary sheep (Ammotragus lervia) for hemoplasma infection.Materials and Methods:A total of 12 blood samples were collected, DNA extracted and further tested by a pan-hemoplasma polymerase chain reaction protocol.Results:Animals were clinically healthy and not infested by ectoparasites. Although housekeeping gene DNA was successfully amplified, all the Barbary sheep samples tested negative for Mycoplasma sp.Conclusion:Notwithstanding the negative results, molecular pathogen surveys on Barbary sheep and other exotic wild mammals may provide insights regarding infection of endangered species caused by captivity stress in association with exposure to new pathogens worldwide.
