visceral leishmaniasis (vl) is an emerging zoonosis disease in countries of the mediterranean basin caused by leishmania infantum. although domestic dogs are the main vertebrate hosts, many wild carnivores have been considered playing a role in the spreading of vl. sporadic numbers of dog and human vl have been reported in golestan province in north iran. the present study was performed to dete...

Visceral leishmaniasis, associated with HIV/AIDS coinfection, is becoming a more aggressive disease, complicating an accurate prognosis. A 21-year-old HIV-positive female presenting with clinical features of visceral leishmaniasis was enrolled in this study. Bone marrow cytology, Novy-MacNeal-Nicolle culture and kDNA PCR of peripheral blood were all positive. Typing methods, multilocus enzyme e...

visceral leishmaniasis (kala-azar) is a serious health problem in some northern and south western parts of iran. the incidence of kala-azar caused by leishmania infantum has recently increased in nourabad-mamassani district of fars province, in the south of the country. this study was designed to determine the role of asymptomatic dogs as host reservoir of l. infantum in this new formed focus a...

The effect of Triton X-100, Na cholate and Tween 80 on the solubilization of integral membrane proteins in intact cells, spheroplasts and inner-membrane fragments of Salmonella typhimurium was studied. The detergents were used in various concentrations (1.6 to 64 mM) and cytochromes b and d were used as marker to monitor the solubilization of membrane-bound proteins. Results showed that no inne...

The transmission of Trypanosoma cruzi by vectors is confined to the Americas, and the infection circulates in at least two broadly defined transmission cycles occurring in domestic and sylvatic habitats. This study sought to detect and characterize infection by T. cruzi and other trypanosomes using PCR strategies in blood samples from free-ranging howler monkeys, Alouatta caraya, in the northea...
