Cross-contamination of drinking water in residential and public building

There are growing numbers of cross-contamination threats that Could contaminate drinking water. Microbiological contaminants can enter drinking water system through flush toilet system installed inside. Four samples were collected from five floors building to represent the contamination of drinking water. To confirm the results five repitation of the samples were conducted .A total number of samples collected were 96. The MPN/100 ml.of water sample were detected for fecal coliforms. The results suggested that tap water could be a potential transmission route for many diseases and may pose a health hazard

Lower respiratory tract infection among critically iII patients

Sixty-seven selected critically ill patients were included in the study. The aim was to evaluate quantitative culture methods in diagnosing lower respiratory tract infection [LRTI] and to identify the bacterial, fungal and mycoplasma pneumoniae isolates and to determine their antibiograms. Out of the sixty-seven studied patients, two hundred and thirty-seven organisms belonging to seventeen species were isolated. Staph. Aureus represented 34.3%, followed by P. aeruginosa 32.8%, while, H. Influenzae and Ent. cloacae were isolated from 17.9% and 14.9% of patients, respectively, M. Pneumoniae was identified in 10.4% and C. albicans was isolated in 9% of cases only

Morphotyping as a tool for characterization of candida albicans

A new morphological system was used to differentiate clinical [mainly diabetics] and environmental C. Albicans isolates. The numerical codes were assigned primarily on the basis of the nature and extent of marginal fringing and the surface topography of the streak colony. Such differentiation reveals special types that were confined to clinical isolates and others for environmental ones. While 2 types showed in both isolates, this may indicate the importance of environmental isolates in transmitting diseases. The system was a simple and reproducible means for epidemiological studies of Candida and Candidosis

Candida associated diarrhoea in hospitalized children

Human candidosis is receiving considerable medical interest because of the widespread use of antibiotics, corticosteroids and immunosuppressive drugs. A total of 180 hospitalized children, who developed diarrhea after being medicated, were interviewed for inquiry about the characteristics of diarrhea and drugs prescribed to them. Candida positive diarrhea was detected in 114 cases [63.33%], 52.6 of them were caused by C. albicans. However, no significant variation by age, sex and drugs could be detected

Study of combination effects of nystatin and clotrimazole with some antibiotics on candida albicans

Binary combinations between 2 antifungal agents nystatin and clotrimazole and 4 antibiotics tetracyclines, chloramphenicol, rifampicin and gentamicin were tried using 7 Candida albicans strains isolated from clinical specimen using the checker board method. The best combinations were obtained with nystatin-tetracyclines and clotrimazole- gentamicin. However, synergistic activity between the 2 antifungal agents and these antibiotics was found only at high concentrations of the latter 500 ug - 125 ug/ml, thus limiting its application in vivo

study on the effect of some antimicrobial agents on candida albicans strains

One hundred strains of C. albicans from different clinical and environmental sources were tested to evaluate their sensitivity to some antibacterial and antifungal agents [tetracycline, chloramphenicol, miconazole and nystatin and their combinations in pairs]. Tetracycline and chloramphenicol and combination of both drugs had no inhibitory effect on the growth of all isolates of C. albicans tested at maximum concentration [20 ug/ml]. However, tetracycline, but not chloramphenicol, was found to enhance the growth of C. albicans. C. albicans was sensitive to nystatin [MIC 12.5 to 100 ug/ml], but highly sensitive to MCZ [MIC 0.005 to 50 ug/ml]. Combination of antifungals and antibiotics tested exerted synergistic activity against all isolates of C. albicans in different concentration. For instance MCZ with tetracycline [MIC 0.005 to 12.5 ug/ml], MCZ with chloramphenicol [MIC 0.005 to 25 ug/ml], combination of nystatin with tetracycline [MIC 78 to 100 ug/ml] and nystatin with chloramphenicol [MIC 6.25 to 100 ug/ml]. The pathogenic isolates of C. albicans were more resistant than nonpathogenic and environmental isolates to antifungal and their combinations with antibacterial antibiotics used

Beta-hemolytic streptococcal carriage-with special reference to group G-among food handlers in Alexandria

Previous reports emphasized the role of food as a vehicle of transmission and spreading of group G-BHS infection. The study aimed to determine the rate of BHS carriage among food handlers in Alexandria with special reference to group G. Throat swabs were taken from 180 food handlers and cultured to isolate beta hemolytic streptococci. The results showed that 57 out of 180 [31.7%] food handlers were carriers for BHS. The highest percentage of carriage was for group A [13.3%], followed by group G [8.3%]
