SUMMARYOesophagus samples from 714 cattle from Western Australia were examined by artificial digestion to detect the presence of Sarcocystis spp. The overall prevalence of infection was 52%. The prevalence of infection increased with age and was highest in the entire males (92%). The prevalence was lower in cattle which originated from arid and semiarid regions (9 and 31% respectively) than those from tropical (87%) and temperate (60%) regions. possible reasons for these differences are discussed and it is concluded that environmental and management factors as well as host age and sex influence the prevalence of infection with Sarcocystis spp. in cattle.

Intracellular Protozoan Parasite

Sarcocystis is an intracellular protozoan parasite in the phylum Apicomplexa. It is widely distributed all over the world. There are scarce reports about chicken Sarcocystis. From February 2016 to January 2018, a total number of 630 chicken carcasses, intestines and viscera were collected from different chicken markets in Menoufia and Gharbia Governorates, Middle region of the Nile Delta, Egypt and carefully inspected. Macroscopic and microscopic cysts of Sarcocystis spp. were found in the intestinal wall and mesentery of 5 birds. Histopathological sections revealed the presence of two shapes of the macroscopic cysts (oval and kidney shape). Their wall was striated and characterised by the presence of radial septa. It had compartments mostly of hexagonal shape, containing both bradyzoites and metrocytes in the periphery. The bradyzoites were banana-shaped and measured 20–30 × 8–10 μm with centrally or posteriorly located nuclei. Microscopic cysts of Sarcocystis spp. were detected in-between muscle bundles, with variable shapes (spindle and oval).

RESUMO: Amostras de sangue de 303 equinos provenientes de 56 propriedades do município de Rorainópolis, Roraima, foram avaliadas por Reação de Imunofluorescência Indireta (RIF) para pesquisa de anticorpos contra Sarcocystis neurona, Toxoplasma gondii e Neospora spp. Algumas amostras de soros positivos para Sarcocystis spp. foram avaliadas pelo Western Blotting (WB) utilizando antígenos crus de S. neurona. A partir dos resultados sorológicos, possíveis fatores de risco foram avaliados frente a variáveis individuais e de propriedade. A prevalência de anticorpos anti-Sarcocystis spp. foi estimada em 43,2% (37,6-49,0%), anti-Neospora sp. em 26,7% (21,9-32,2%) e anti-T. gondii de 18,5% (14,3-23,4%). Quatorze amostras (14/15) testadas por WB resultaram positivas para antígenos de S. neurona. Das propriedades, 76,8% (43/56) apresentaram pelo menos um equino positivo para Sarcocystis spp.; 69,6% (39/56) para Neospora spp. e 55,4% (31/56) para T. gondii. Dos equinos, 13 (4,3%) apresentarem anticorpos para os três agentes, 50 (16,5%) para Sarcocystis spp. e Neospora spp., 10 (3,3%) para Neospora spp. e T. gondii, e oito (2,6%) para Sarcocystis spp. e T. gondii. As variáveis associadas (P≤0,05) à presença de anticorpos foram: para Neospora spp. não pastejar em áreas alugadas, ausência de assistência veterinária na propriedade, sexo masculino, não estabular animais e plantel equino acima de 5 animais; enquanto para T. gondii foram o contato com felinos, animais da raça lavradeiro, animal estabulado, criação de bovinos na propriedade e plantel equino acima de 5 animais. Não houveram variáveis associadas a presença de anticorpos contra S. neurona. Relata-se no presente estudo a primeira detecção de anticorpos anti-S. neurona, Neospora spp. e T. gondii em equinos do estado de Roraima, localizado na Amazônia Setentrional Brasileira, ressaltando para a elevada frequência de fazendas com equinos soropositivos.

The exact prevalence of Sarcocystis spp. infection in animals slaughtered for food is unknown in Lithuania. Therefore, the present study was initiated to evaluate Sarcocystis spp. infection in the carcasses of cattle (n = 206), sheep (n = 61), pigs (n = 73) and horses (n = 72) raised in Lithuania for food. The prevalence and intensity of Sarcocystis spp. infection were assessed under light microscopy by analysing 1 g of stained and squashed muscle samples. All the investigated muscle types (oesophagus, diaphragm, heart, neck, jaw, back, leg and tongue) were found to have been infected with microcysts rather than with macrocysts. A high prevalence of infection was established in cattle (44.9–98.1%) and sheep (100%), whereas the prevalence of this infection in pigs (30.1–50.0%) and horses (34.7–63.9%) was considered to be moderate. Significant differences in the infection prevalence were detected in the majority of muscle groups of cattle and in some muscle groups of pigs and horses. Similarly, significant differences in the median (Md) intensity of infection were observed in the majority of the muscle groups of cattle (Md = 4–29) and sheep (Md = 21–73) and only in some muscle groups of pigs (Md = 4.5–16) and horses (Md = 1–3). Cases of intense infection (> 40 cysts in a sample) were relatively often detected in sheep (44.9%) and cattle (19.1%), and rarely in pigs (3.7%). Hence, based on the varying rates of infection in the examined samples, the infection was identified as being intense in sheep and cattle, moderate in pigs and low in horses.
