The seroprevalence of Sarcocystis spp. and Toxoplasma gondii was researched in swine raised in Santa Maria, RS, Brazil. Serum samples from 84 pigs from 31 farms were tested using indirect immunofluorescence assay (IFA) for both agents. Additionally, 53 samples of pork sausages and tissues destined for human consumption, including: salami, sausage, black pudding, heart, tongue, brain, and rib muscle, were submitted to PCR to detect DNA for each agent. The frequency of anti-Sarcocystis spp. antibodies was 36.9% (31/84), with titers ranging from 32 to 1024, and 25% (21/84) for anti-T. gondii antibodies, with titers ranging from 64 to 2048. Sarcocystis spp. and T. gondii DNA were detected in 67.9% (36/53) and 13.2% (7/53) of samples, respectively. The presence of antibodies and the detection of DNA from Sarcocystis spp., and T. gondii suggests that the pigs were infected and may serve as an important reservoir for both parasites. The infection by these protozoa in the swine population is relevant to public health due to their zoonotic potential.
As pesquisas com produtos naturais representam um valioso recurso, pois são fonte de compostos biologicamente ativos que podem ter atividade contra uma variedade de patógenos que afetam a saúde humana e animal. Os dípteros da espécie Lucilia cuprina, pertencente à família Calliphoridae, conhecidos como moscas varejeiras, são cosmopolitas e têm importante função na natureza devido ao desenvolvimento de suas larvas em matéria orgânica em decomposição. Alguns estudos chegaram à conclusão de que a produção de enzimas digestivas secretadas pelas larvas são importantes para o estabelecimento e sobrevivência desses insetos no hospedeiro e no ambiente devido a sua secreção ter ação bactericida, antiparasitária e antifúngica e ao hábito alimentar necrobiontófago, esses dipteros têm sido utilizados em bioterapia e pesquisas contra
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
