Fecal samples from 248 lambs, from 19 farms, were tested for the presence of oocysts. In this study, the frequency of Eimeria species was evaluated in lambs from the southern region of the Rio Grande do Sul state, Brazil. Eimeria crandallis and Eimeria ovinoidalis are considered the most pathogenic, causing reduced growth, dehydration, anorexia, and death. Lambs are more susceptible to coccidiosis, especially in stressful conditions, being infected by different species of the parasite. This study revealed that Microcerella halli (Engel) and Peckia (Euboettcheria) australis (Townsend) are the most important species for PMI estimation in Southern Brazil, as they are often found breeding in corpses in this region.ĪBSTRACT: Eimeria infections are common in the sheep industry worldwide. Moreover, five myiasis-causing sarcophagine flies recorded in Southern Brazil were considered to have the potential to reveal cases of neglect or mistreatment. Considering the importance of species for PMI estimation, 10, 42, and 39 species were classified as having high, moderate, or no forensic relevance, respectively. The checklist for Southern Brazil comprises 91 species distributed in 19 genera, with Oxysarcodexia, Peckia, and Lepidodexia representing the richest genera. Dexosarcophaga carvalhoi (Lopes) was registered for the first time in Southern Brazil. Oxysarcodexia was the most abundant and species-rich genus in all three studies. A total of 2,831 specimens representing 38 taxa were collected from three studies. The forensic importance (high, moderate, or none) of the recorded flesh flies for estimating the postmortem interval (PMI) or inferring cases of neglect was determined based on their ecological habits. A robust and updated checklist of Sarcophaginae flies recorded in Southern Brazil is presented, based on material collected in the Rio Grande do Sul state and on a literature review. Flesh flies comprise a large fly family distributed worldwide that has great importance for forensic entomology.
