The aim of this communication was to establish if Enterobacterales associated with gulls in Argentina harbored antimicrobial resistance (AMR) genes. We analyzed cloacal swabs two contrasting areas: Ensenada, Buenos Aires province (26 Larus dominicanus and 22 Chroicocephalus maculipennis) Puerto Madryn, Chubut (20 L. dominicanus). In bla CTX-M mcr-1 genes, were isolated from both gull species, w...

Characteristics of mosquito larval habitats are important in determining whether they can survive and successfully complete their developmental stages. Therefore, data on the ecological factors affecting mosquito density and abundance especially the physicochemical properties of water of their breeding sites, can possibly be helpful in implementing larval management programs. Mosquito larvae we...

b a ckground : this study aimed to identify and determine the larval and adult mosquitoes (culicidae) fauna in hamedan county, western iran. m e t hods: it was a cross-sectional study which took place in four area of the hamedan county. sampling methods for larvae, pupae and adults were dipping, hand catch, night catch and total catch. larvae and adult mosquitoes col- lected and were sent to la...

b a ckground: several important diseases are transmitted by mosquitoes. despite of the potential of the occurrence of some mosquito-borne diseases such as west nile, dirofilariasis and malaria in the region, there is no recent study of mosquitoes in west azerbaijan province. the aim of this investigation was to study the fauna, composition and dis- tribution of mosquitoes and the characteristic...

To investigate the involvement of lizard species in the natural cycle of Borrelia burgdorferi sensu lato (s.l.) in Hungary, a total of 186 reptiles belonging to three species--126 green lizards (Lacerta viridis), 40 Balkan wall lizards (Podarcis taurica), and 20 sand lizards (Lacerta agilis)--were captured in 2007 and 2008. All ticks removed from the lizards were Ixodes ricinus, either larvae (...

PATIENTS who return from the tropics may present a great variety of clinical syndromes. They may present themselves as a pyrexia of unknown origin, requiring special investigations for such conditions as malaria or visceral leishmaniasis, or with the dysenteric syndrome, requiring sigmoidoscopy and search for entamoeba histolytica in scrapings from the bowel. There may be undue loss of weight w...

The genus Leptophion is recorded for the first time from Vietnam, including new records of three species, viz. L. giganteus Shimizu & Watanabe, maculipennis (Cameron) and radiatus (Uchida), country. comparative morphological pictorial characters Vietnamese specimens were given. In addition, variations in-country distribution newly species also provided.

background : ecological studies on mosquitoes are very important in vector control programs. there are a few studies about the ecology of mosquitoes in northern iran. this study was carried out to detect fauna and larval habitat characteristics of mosquitoes. methods : this study aimed to determine fauna and the ecology of mosquitoes in neka county, mazandaran province, northern iran from april...

In mosquitoes, spirochetes were first detected in 1907, when Jaffé reported a spirochete in Culex sp. and named it Spirochaeta culicis (Arch. Protistenkd. 9: 100-107.). Spirochetes were also detected in Anopheles funestus and A. maculipennis (Sinton J.A., Shute P.G. 1939: J. Trop. Med. Hyg. 42: 125-126) and in the salivary glands of Anopheles gambiae (Masseguin A., Palinacci A. 1954: Bull. Soc....
