| comparison of black fly species (diptera: simuliidae) on an amerindian reservation with a high prevalence of fogo selvagem to neighboring disease-free sites in the state of mato grosso do sul, brazil. the cooperative group on fogo selvagem research. | fogo selvagem is an autoimmune blistering skin disease that principally occurs among rural brazilians living in geographically clumped disease foci. exposure to hematophagous black flies possibly is related to the cause of the disease. we compared the occurrence, proportions, and richness of simuliid species immatures and the biting activity of adult females within a recently discovered, high prevalence focus of fogo selvagem, the limão verde terena reservation, to that of neighboring regions wi ... | 1998 | 9538571 |
| an insight into the sialotranscriptome of simulium nigrimanum, a black fly associated with fogo selvagem in south america. | pemphigus foliaceus is a life threatening skin disease that is associated with autoimmunity to desmoglein, a skin protein involved in the adhesion of keratinocytes. this disease is endemic in certain areas of south america, suggesting the mediation of environmental factors triggering autoimmunity. among the possible environmental factors, exposure to bites of black flies, in particular simulium nigrimanum has been suggested. in this work, we describe the sialotranscriptome of adult female s. nig ... | 0 | 20519601 |
| simplagrin, a platelet aggregation inhibitor from simulium nigrimanum salivary glands specifically binds to the von willebrand factor receptor in collagen and inhibits carotid thrombus formation in vivo. | among the several challenges faced by bloodsucking arthropods, the vertebrate hemostatic response against blood loss represents an important barrier to efficient blood feeding. here we report the first inhibitor of collagen-induced platelet aggregation derived from the salivary glands of a black fly (simulium nigrimanum), named simplagrin. | 2014 | 24921659 |
| insights into the epidemiological link between biting flies and pemphigus foliaceus in southeastern brazil. | black fly and sandfly bites are related to the endemicity of pemphigus foliaceus (pf); however, an immune reaction against the salivary proteins from these flies still requires confirmation in the case of pf patients living in southeastern brazil. | 2017 | 28941730 |
| diversity and microdistribution of black fly (diptera: simuliidae) assemblages in the tropical savanna streams of the brazilian cerrado. | we describe the abiotic factors affecting the distribution of black flies at a microhabitat scale, rather than at the regional scale usually present in the literature on the neotropics. black fly larvae were sampled from the tocantins river and three tributaries, located in the brazilian savanna (state of tocantins, brazil) during six bi-monthly sampling periods from october 2004-august 2005. at each sampling site, 15 random quadrats (30 x 30 cm) were sampled each period and for each quadrat wer ... | 2012 | 22510832 |
| [new synonyms and corrections in simulium with the revalidation of s. pruinosum lutz, 1904 (culicomorpha, simuliidae)]. | the following synonyms are proposed: simulium antunesi (lane & porto, 1940), simulium mauense nunes de mello, 1974 and simulium nilesi rambajam, 1979 are synonyms of simulium perflavum roubaud, 1906; simulium sucamense nunes de mello, 1974 and simulium santaelenae ramírez-pérez & peterson, 1981 are synonyms of simulium (psilopelmia) iracouboense floch & abonnenc, 1946; simulium major lane & porto, 1940 are synonym of simulium (hemicnetha) rubrithorax lutz, 1909. the recent use of the miswriting ... | 1989 | 2617119 |
