We describe here a case of multiple colonization of a male cadaver found indoors in the municipality of Jaboatao dos Guararapes, Brazil. The body was colonized by six species of Diptera: Chrysomya albiceps, Chrysomya megacephala, Chrysomya putoria (Calliphoridae), Megaselia scalaris (Phoridae), Fannia trimaculata (Fanniidae), and Peckia (Peckia) chrysostoma (Sarcophagidae). The most abundant species were C. albiceps (65.0 % of all emerged adults) and C. megacephala (18.6 %). The case illustrates the ability of six insect species to simultaneously colonize a corpse in an indoor environment and represents the first collaboration between the forensic police and entomologists in Northeastern Brazil. We provide here the first record of two species, F. trimaculata and Peckia (P.) chrysostoma colonizing a human cadaver. We also report the first case of cadaver colonization by C. putoria and M. scalaris in Northeastern Brazil. Information on the development time of two species, C. albiceps and C. megacephala, were used to discuss the estimation of the post-mortem interval. Considering that the region harbors the highest rates of homicide in Brazil, implications of these findings for the consolidation of forensic entomology in the regio...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
