Susceptibility of Phlebotomus argentipes
against DDT in endemic districts of North Bihar, India.
Visceral leishmaniasis on the Indian sub-continent: a multi-centre study of the cost of three interventions for the control of the sandfly vector, Phlebotomus argentipes
Transmission of Indian kala-azar to man by the bites of Phlebotomus argentipes
Measurement of recent exposure to Phlebotomus argentipes
, the vector of Indian visceral leishmaniasis, by using human antibody responses to fly saliva.
Method of estimation of KA cases with intervention has already been mentioned in the earlier section, however, the estimation of KA cases without intervention is determined by many factors, for example, vector density, densities of Phlebotomus argentipes
(Diptera: Psychodidae), disease transmission, population growth rate, existing effectiveness of IRS, current incidence rate, climate and environmental factors, household behaviour among others.
These data are consistent with data on the feeding behavior of Phlebotomus argentipes
blood-sucking flies, reported previously (22).
Resurgence of Phlebotomus argentipes
and Papatasi in part of Bihar (India) after DDT spraying.
Natural infection of Phlebotomus argentipes
with Leishmania and other trypanosomatids in a visceral leishmaniasis endemic region of Nepal.
Sand fly bloodmeal analysis in India confirms that Phlebotomus argentipes
feed predominantly on bovines, with humans as their second choice (17).
Survey of sandflies in the Himalayan region has established the presence of Phlebotomus argentipes
Visceral leishmaniasis, popularly known as kala-azar in Indian subcontinent is a vector-borne disease caused by the trypanosomatid parasite Leishmania donovani in the Indian subcontinent and is transmitted by Phlebotomus argentipes
The presence of Phlebotomus argentipes
, the established vector of the visceral form of leishmaniasis caused by L.
is the proven vector of kala-azar in India (4).
Favouring factors are: human beings the only reservoir host; Phlebotomus argentipes
the only vector in the region; VL focalized in 109 districts in three countries; the disease easy to diagnose even in field settings through recently developed rK39 dipstick test and can be treated completely with effective drugs.
