Excretion of carbon dioxide and L-lactic acid through exhalation and perspiration provides olfactory signals to mosquitoes which allow them to find and bite humans; however, mosquito species differ in this regard. This study investigated upwind responses of Anopheles stephensi, mysorensis form, an important malaria vector in Asia, to carbon dioxide and L-lactic acid under laboratory conditions....

Tinea capitis has a high incidence with a global changing pathogen distribution, making this condition a public health concern around the world. As the infection is initially asymptomatic, it is easily spread. Moreover, it is present in many fomites, including hairbrushes, pillows, and bedding. Prompt recognition and treatment is necessary for kerion, an inflammatory subtype characterized by te...

Mosquito collections were made in and near Costa Marques, Rondonia, Brazil, to determine anopheline anthropophilic/zoophilic behavior. Collections from a non-illuminated, bovine-baited trap and indoor and outdoor human-bait collections were compared. Anopheles darlingi and Anopheles deaneorum were more anthropophilic than the other anophelines collected. The remainder of the Anopheles species w...

A total of 68 soil samples was collected from "favelas" (slums), schools, public squares, beaches and vacant lots in the city of João Pessoa-PB, Brazil. A search for dermatophytes in these soils was carried out by using the Vanbreuseghem technique. As a result, 48 strains and 6 dermatophytes species were isolated. Trichophyton terrestre (25.0%), Microsporum gypseum (20.8%) and Anthroderma gypse...

BACKGROUND Trichophyton verrucosum is a zoophilic fungus with a worldwide distribution. Our aim was to investigate the proliferative effect of antigenic compounds of T. verrucosum on dermis fibro blasts and endothelial cells. METHODS T. verrucosum was cultured in SCC medium and was then transferred to a broth medium. Surface antigens of this fungus were separated using the freeze and thaw met...

Behavioural variation in the South American malaria vector Anopheles darlingi is described. At the centre of its distribution, in forest areas close to the city of Manaus, Brazil, it is primarily exophagic and exophilic. Mosquitoes from this area are chromosomally diverse. Towards the northern edge of its distribution (in Guyana and Venezuela) it is more endophagic and less diverse chromosomall...

Tinea capitis (TC) is the dermatophytosis widespread in the world[1,2]. Not only specter of causative species in a specific geographical area is changing in time, but also the distribution of each one worldwide. No data exists on TC for recent 25 years in our country. Following goals were set for the study: to determine the specter of TC causatives and importance of age and sex in disease devel...

©2000 Revista Iberoamericana de Micología Apdo. 699, E-48080 Bilbao (Spain) Dermatophytes are cited among the most frequent causes of dermatological problems in domestic animals. The superficial mycoses caused by dermatophytes are called dermatophytosis, and they are commonly referred to as ringworm or tinea. In general, dermatophytes do not invade subcutaneous or deep tissues, but pseudotumora...
