Seroprevalence of Leptospira icterohemorhagia in the field rats and domestic animals

This work was done on 1433 serum sample[470 rats, 353 cows, 372, buffalos, 161 sheeps and 77 goats]collected from 3 different localities in Dakahlia Governorate, and examined for the seroprevalence of Leptospira icterohaemrhagia by the complement fixation test. The result of the study indicate that the leptospira icterohemorhagia is carried by[10.4%] of rats collected, which is highly significant compared to the carrier rate of cows [4.8%], buffalos [3.76%] sheep [2.48%] and goats [0.05]. There was no significant difference in the carrier rate in rats and domestic animals as regard the localities from which the animals collected

Incidence of rubella, herpes simplex, and cytomegalovirus antibodies in mentally retarded children

This work was done on 48 children with unclassifiable mental retardation, in addition to 48 normal healthy children as a control. All cases were in vestigated for the presence of rubella, herpevirus and cytomegalovirus lgG antibodies using ELISA technique. lgG antibody levels for test and control groups respectively were 2.14 +/- 1.62 and 2.62 +/- 1.75 for rubella, 1.140 +/- 628 and 1.472 +/- 0.381 for herpes virus and 0.401 +/- 0.208 and 0.368 +/- 0.164 for CMV denoting that there is no significant difference in antibody levels between test and control groups. Similarly, it was found that there is no significant difference in the level of these antibodies between cases with microcephaly and normocephaly, cases with and without deafness and cases with and without ophthalmic defects in test group cases. Accordingly, we can say that there is no clinical association between any of these viruses [evaluated by lgG antibody levels] at one hand and mental retardation or its manifestation, represented by microcephaly, deafness and ophthalmic defects, on the other hand

Antibiotic concentration into the sinus secretions in case of chronic maxillary sinusitis

The ability of different antibiotics to penetrate into the diseased maxillary sinus mucosa and to sinus secretion was investigated in patients with chronic maxillary sinusitis. 50 patients were given a course either of rifampicin [18 patients], cephalexin [16 patient] or ampicillin [16 patient], 60 aspirated, and 90 irrigated secretion samples were assessed for determination of the concentration of these antibiotice. The highest concentration was achieved with rifampicin and the lowest was with cephalexin

Intekoital and foecal escherichia coli o-serotypes and its relationship to bacteriuria during pregnancy

Cultures from interoital swab, ectal swab and urine specimen elected from 130 patients who had a history of recurrent urinary tract infection. The intertal and rectal E. coli count increased significantly with the urinary count. The prognostic importance of the interoital swab cultures is shown during the follow up by the fact that 60% of the cases develop urinary tract infection when the original interiotal swab E. coli, while only 40% develop urinary tract infection when the initial interoital swab was negative. This difference is statistically significant. The infections were found to occur early in cases with initial E. coli, Patients who developed urinary tract infection were significantly older. There was a higher incidence of corrospondence between the urinary E. coli and the faecal and interoital E. coli strains in symptomatic cases than in asymptomatic bacteriuria indicating that the symptomatic urinary tract infections were not preceeded by asymptomatic bacteriuria. The most frequent E. coli O-group was 0-6. This suggests that E. coli 0-6 group is pathogenic for urinary tract. E. coli 0-6 showed corrospondence between urinary, interiotal and faecal isolates. The results suggest that the availability of E. coli in the vestibular and recte flora constitutes a permissive factor for ascending urinary tract infections to occur
