ABSTRACT
Hundred water samples were collected from different sources in Alexandria and were subjected to membrane filtration examination for detection of Campylobacter jejuni. Fourteen [14%] out of 100 water samples revealed Campylobacter jejuni; eight [40%] from Mahmoudia Canal, four [20%] from lake Maryout and two [10%] from Zeer stored water. The relation between the occurrence of fecal Coliform and Campylobacter jejuni was studied. In all water samples positive for Campylobacter jejuni, fecal Coliforms were isolated but the reverse was not true

This study was carried out on visually handicapped school children of Alexandria El Nour Schools [120 pupils]. A control group [121 pupils] was selected from the ordinary schools matched for age, sex and geographical area. Data were collected through a questionnaire interview. Samples were collected from different sites of lesions. In case of absence of lesions, the feet were examined for occult Tinea pedis and their interdigital spaces were sampled. Visually handicapped school children had significantly higher proportion [65.83%] of skin lesions compared to controls [35.54%]. The proportion of moderate and severe skin lesions among visually handicapped [65.8%] was significantly higher than the corresponding controls [43.9%]. A significant higher proportion of mycopositives among visually handicapped [35.83%] compared to controls [22.31%] was observed. The distribution of mycopositive samples among visiually handicapped and controls by sex was not statistically significant. The proportion of isolated Candida albicans among visually handicapped was significantly higher [16.7%] than that of the corresponding controls [7.4%]
