The role of peridomestic structure and farming activity on triatomine infestation was studied on two vector species of Chagas disease (Triatoma pseudomaculata and T. brasiliensis) in Bahia State, northeastern Brazil. A randomly selected population issued from 136 farms was divided into four categories according to the householder activity. At regional scale, the dwellings of farmers working on ...
We report results of PCR-DNA based detection of Trypanosoma cruzi in wild mammal reservoirs from a chagasic area of Chile. We analyzed 157 blood samples from wild mammals including the marsupial Thylamis elegans and the rodents Octodon degus, Phyllotis darwini, and Abrothrix olivaceus. In addition, 42 blood samples from goats (i.e., a peridomestic mammal) were analyzed. Blood samples were used ...
During 2013, a novel avian-origin H7N9 influenza A virus (IAV) emerged in China and subsequently caused large economic and public health burdens. We experimentally infected three common peridomestic wild mammals with H7N9 (A/Anhui/1/2013) IAV. Striped skunks exhibited the highest burden of disease followed by raccoons and cottontail rabbits. Striped skunks also produced the highest levels of vi...
To determine whether the pathogenic Lyme disease spirochete Borrelia spielmanii is adapted exclusively to garden dormice, we compared the reservoir competence of various rodent species for this spirochete, including sympatric and peridomestic rodents. The different kinds of rodents varied in their attractiveness to nymphal ticks and their level of susceptibility to tick-borne B. spielmanii infe...
Phylogenetic evidence suggests that endemic and epidemic dengue viruses (DENV), transmitted among humans by the anthropophilic mosquitoes Aedes aegypti and Ae. albopictus, emerged when ancestral, sylvatic DENV transmitted among nonhuman primates by sylvatic Aedes mosquitoes adapted to these peridomestic vectors. We tested this hypothesis by retrospectively examining evidence for adaptation of e...
Rhodnius ecuadoriensis is considered the second most important vector of Chagas disease in Ecuador. It is distributed across six of the 24 provinces and occupies intradomiciliary, peridomiciliary and sylvatic habitats. This study was conducted in six communities within the coastal province of Guayas. Triatomine searches were conducted in domestic and peridomestic habitats and bird nests using m...
Eggs of Toxocara cati were found in the feces of Didelphis albiventris from a peridomestic urban environment in Brazil. Negative fecal tests following short-term captivity of the opossums, as well as the absence of ascaridids during necropsy, suggest the occurrence of pseudoparasitism. Implications of the findings for the epidemiology of toxocariasis are discussed.
Replicative capacity of Middle East respiratory syndrome coronavirus (MERS-CoV) was assessed in cell lines derived from livestock and peridomestic small mammals on the Arabian Peninsula. Only cell lines originating from goats and camels showed efficient replication of MERS-CoV. These results provide direction in the search for the intermediate host of MERS-CoV.
