A large number of Sarcocystis spp. infect birds as intermediate hosts, but pigeons are rarely affected. We identified a novel Sarcocystis sp. that causes lethal neurologic disease in domestic pigeons in Germany. Experimental infections indicated transmission by northern goshawks, and sequence analyses indicated transnational distribution. Worldwide spread is possible.

Macrocysts of the protozoan parasite Sarcocystis spp. occurred in 34 of 241 (14%) adult and 6 of 70 (8.6%) immature mottled ducks (Anas fulvigula) that were collected in southwestern Louisiana from 1987 to 1989. The prevalence of Sarcocystis spp. among immature ducks was higher than previously reported, possibly because of a longer exposure period. No differences in carcass composition variable...

1. Guinea-pigs, naturally uninfected by sarcosporidia, were infected by feeding them with rat's muscle that was naturally infected by Sarcocystis muris, and by ripe mobile sporozoites from the same source. The infection was not visible grossly, but was detected upon very careful search through many sections of muscle. 2. Sarcosporidia were not found in the guinea-pigs until after an interval of...

Background: Sarcocystosis is one of the most distributed parasitic diseases over the world, caused by Sarcocystis spp. In this study, we assessed the effect of electron beam irradiation on the viability of Sarcocystis spp. in beef.  Methods: Experimental beef groups were irradiated by four different electron beam doses of 1, 2, 3, and 4 kGy, at intervals of 0 and 24 h after irradiation, then t...

Four valid species of Sarcocystis have been reported from the water buffalo (Bubalus bubalis): Sarcocystis fusiformis, Sarcocystis buffalonis, Sarcocystis levinei and Sarcocystis dubeyi. Here, we redescribe structure of S. fusiformis sarcocysts by scanning and transmission electron microscopy (SEM, TEM). Twenty-one macroscopic sarcocysts from oesophagus of the water buffalo in Egypt were examin...

Bovine sarcocystosis is an economically important disease worldwide caused by the apicomplexan protozoan, Sarcocystis species. There are three main species of cattle Sarcocystis; S. cruzi (S. bovicanis), S. hirsuta (S. bovifelis) and S. hominis (S. bovihominis). The current study was conducted to identify Sarcocystis species infecting slaughtered cattle at Sharkia province, Egypt using light an...

a simple special protocol using semichon’s acetic carmine stain was applied for examination of muscles of some small mammals, naturally infected with sarcocystis spp. using this method, infected muscles fibers with sarcocystis could easily be differentiated from muscle tissues. this method can be applied for screening of infected muscles with sarcocystis cysts on large number of samples for epi...

An outbreak of fever associated with myalgia and myositis occurred in 2012 among 89 of 92 college students and teachers who visited Pangkor Island, Malaysia. The Sarcocystis nesbitti 18S rRNA gene and sarcocysts were obtained from muscle tissues of 2 students. Our findings indicate emergence of S. nesbitti infections in humans in Malaysia.
