Sand fly population dynamics and cutaneous leishmaniasis among soldiers in an Atlantic forest remnant in northeastern Brazil

摘要: Outbreaks of cutaneous leishmaniasis are relatively common among soldiers involved in nocturnal activities tropical forests. We investigated the population dynamics sand flies a military training camp located remnant Atlantic rainforest northeastern Brazil, where outbreaks have sporadically been described. From July 2012 to 2014, light traps were monthly placed 10 collection sites, being nine sites near forest edge and one sheep goat stable. Light operated from 5:00 pm 6:00 am, during four consecutive nights. Leishmania infection was assessed using fast real-time PCR assay. Cases also investigated. In total, 24,606 belonging 25 species identified. Males (n = 12,683) predominated over females 11,923). Sand present all months, more numerous March 1,691) April 2013 3,324). Lutzomyia choti (72.9%) most abundant species, followed by longispina (13.8%), complexa (5.3%), representing together >90% collected. Forty cases recorded January December 2014. isolates obtained eight patients characterized as braziliensis. Soldiers anyone overnighting remnants should adopt preventative measures such use repellents on bare skin or clothes insecticide-treated tents.
