effect of diurnal fluctuating temperature on the development of S haematobium in B truncatus

ABSTRACT

A comparative study of the prepatent period, infection rate and cercarial production of S. haematobium using B. truncatus at a constant temperature of 25 °C and at a sinusoidally fluctuating temperature between 20°C and 30°C.The studied parameters were found almost the same in both conditions. So, the prepatent period of S. haematobium under field conditions should be related to the mean temperature calculated from the maximum and minimum degrees of water bodies temperature
