Study of the present status of filariasis in an endemic area in Giza governorate, Egypt

ABSTRACT

In a trial to throw some light on the present status of filariasis in Giza Governorate, both human and mosquitoes were surveyed in two endemic areas, Kafr-Ghataty and Azizya. In Kafr-Ghataty the clinical cases detected were very rare [0.77%], while no microfilaremic cases were obtained. The situation was different in Azizya Village, where no clinical cases were detected, but microfilaremic cases were relatively higher [8%]. The results of the larval survey, carried out only in Kafr-Ghataty, showed that Culex pipiens larvae were predominant [99.57%]. They were found in all the breeding places, especially canals and seepages, while Theobaldia longiareolata larvae were rare [0.43%] and present only in wells and cesspits. Regarding the adult mosquitoes survey, Culex pipiens was the only species detected in both areas. The result of dissection of adult female mosquitoes showed that individual dissection failed to detect infection among mosquitoes, in contrast to mass dissection which gave positive results [0.27% in Kafr-Ghataty and 2.2% in Azizya]. It was also found that infective mosquitoes were 0% in Kafr-Ghataty and 1.1% in Azizya
