Phlebotomus papatasi (Scopoli) (Diptera: Psychodidae) is the most important vector of Leishmania major, and previous experiments revealed that Leishmania development in the sand fly midgut is significantly affected by temperature. Therefore, we maintained blood-fed P. papatasi females at 23 or 28 degrees C to understand the effect of temperature on bloodmeal digestion and developmental times of...
BACKGROUND & OBJECTIVES ZCL is a growing threat in many rural areas of Iran which involves 17 out of 31 provinces. This study was conducted from April to November 2011 for evaluation of the efficacy of phostoxin and zinc phosphide against rodents. METHODS Rodent control operations were carried out using phostoxin and zinc phosphide. To evaluate the effect of rodent control operation on the ma...
background cutaneous leishmaniasis (cl) with diverse clinical manifestations is prevalent and remains a major public health problem in iran, while its incidence has been doubled over the last decade. this study was performed for the first time in larestan, fars province, located in southern part of iran to determine infectious patterns in the reservoir hosts and sand fly vectors using parasitol...
Introduction: The cutaneous leishmaniasis has been regularly spread in Iran. Jask County which has been located in the eastern part of Hormozgan province had the most cases of patients. The present study aimed to investigate on the fauna and biology of sand flies. Methods: In this descriptive, cross sectional study, during 2007-2008, sand flies were captured using sticky papers and CDC mi...
BACKGROUND During its developmental cycle within the sand fly vector, Leishmania must survive an early proteolytic attack, escape the peritrophic matrix, and then adhere to the midgut epithelia in order to prevent excretion with remnants of the blood meal. These three steps are critical for the establishment of an infection within the vector and are linked to interactions controlling species-sp...
BACKGROUND The sandfly Phlebotomus papatasi is the vector of Leishmania major, the main causative agent of Old World cutaneous leishmaniasis (CL) in Saudi Arabia. Sandflies inject saliva while feeding and the salivary protein PpSP32 was previously shown to be a biomarker for bite exposure. Here we used recombinant PpSP32 to evaluate human exposure to Ph. papatasi bites, and study the associatio...
Insect galectins are associated with embryonic development or immunity against pathogens. Here, we show that they can be exploited by parasites for survival in their insect hosts. PpGalec, a tandem repeat galectin expressed in the midgut of the sandfly Phlebotomus papatasi, is used by Leishmania major as a receptor for mediating specific binding to the insect midgut, an event crucial for parasi...
