“…In our study isolation of Salmonella, Shigella and Vibrio sp was 3.6, 1.8, and 4.5 per cent respectively which is in agreement with other studies [8,10,14,18,22,25,27], In an outbreak of cholera in Calcutta [17], C. jejuni was isolated in 10 out of 74 diarrhoea cases. Out of these 10 cases, 2 revealed C. jejuni as the sole pathogen and 8 cases were associated with V. cholerae, V. parahaemolytics, A. hydrophilia or A. díspar.…”

This study was carricd out to isolate and identify Campylobacter jejuni from stool samples of patients suffering from diarrhoea. The study spanned a two-year period and C. jejuni was isolated in 10 (4.5%) out of 220 patients of diarrhoea] disorders. In samples of stool collected from 50 healthy individuals, C. jejuni was isolated in one (2%) case. Further, to isolate other enteropathogens alongwitli C. jejuni, procedures were undertaken simultaneously to identify Salmonella, Shigella and Vibrio cltolerae infection. Salmonella sp was isolated in 8 (3.6%), Shigella sp in 4 (1.8%) and Vibrio cholerae in 10 (4.5%) cases out of 220 faecal cultures studied. In one stool specimen Shigella flexneri was isolated alongwith C. jejuni.

“…The involvement of younger age group of patients with diarrhoea has been reported by most of the authors from India and abroad [11][12][13][14][15][16][17][18][22][23][24]. Similarly the distribution of patients suffering from diarrhoea due to C. jejuni showed male preponderance in most of the studies.…”

“…The report shows no significant difference in the rate of bacteriuria in the wet and dry seasons in this environment. This finding disagrees with the belief that microbial infections are more prevalent during the dry season than in the wet season (10,20). The difference may be attributed to the maternal protection of the infants and the importance of breastfeeding (21).…”

“…The greater frequency of neonatal UTI in males has been attributed to structural abnormalities in the urinary tract of males (8) and the differences in their humoral status (9). Seasonal variation has also been shown to influence microbial infection (10) and UTI in infants (11,12).…”

Among the 446 high risk neonates studied for significant bacteriuria and pyuria in the neonatal wards of the Obafemi Awolowo University teaching hospital Complex, Ile-Ife, 7.6% and 5.8% were positive for significant bacteriuria and pyuria respectively, while none of the 81 infants in the control group were positive. Males and females were similarly affected and there was no seasonal variation in the prevalence of pyuria or bacteriuria. It is noteworthy that 25 (96%) of the 26 pyuria neonates also had bacteriuria emphazising the significance of pyuria as a possible screening method for urinary tract infections in neonates. The clinical problems in the neonates studied included prematurity, low birthweight, neonatal jaundice, fever, CNS symptoms, ophthalmia neonatorum, prolonged rupture of the membranes (PROM), respiratory distress, septic cord/skin, diarrhoea, vomiting and feeding problems. Only prematurity and low birthweight were significantly associated with bacteriuria in the neonates studied. The organisms encountered in this study were Escherichia coli (58.4%), Klebsiella species (35.3%) and Proteus species (5.9%). Of the bacterial isolates, 67% were sensitive to Ampicillin and 97% to Gentamycin. The combination of these antibiotics was effective in all cases in the present study. The study has highlighted the need for routine urine culture in our high risk neonates.

Enteropathogenic strains of faecal Escherichia coli produced significantly (P < 0.01) more maltase than the non‐pathogenic strains of the organism. The enzyme was induced by maltose but repressed by glucose and fructose. The maltase was partially purified by ammonium sulphate precipitation, followed by dialysis and gel permeation chromatography. The partially purified maltase had an Mr of 144500 and an apparent Km of approx. 7.6 mM for maltose. The enzyme was stimulated by Ca2+, inhibited by Cu2+, Hg2+, Uo2+, IAA and EDTA, and exhibited optimum activity at pH 6.5 at 30°C.
