lymphocyte cd4 + count, a standard laboratory test for staging of hiv infection, is expensive and unavailable in resource-restricted countries. total lymphocyte count (tlc) and hemoglobin (hb) are recommended as simple & inexpensive surrogates. the aim of this study was to assess the correlation, sensitivity and predictive power of these parameters as substitutes for cd 4 count. one hundred hiv...

Previous studies have shown that mismanaged swimming pools could transmit water-borne diseases. The objective of the present study was the quality assessment of chemical, biological and physical characteristics of swimming pools in Shahrekord city, southwest of Iran. The two main indoor swimming pools of Shahrekord city were considered during the summer and winter of 2013. The number of 459 sam...

Abstract The presence of pathogenic bacteria in shrimp culture water could influence the growth and production. This research aimed to quantify total coliform, Escherichia coli Vibrio pond Vannamei ( Litopenaeus vannamei ) Rupat Island. Water samples from inlet (IW), three ponds (PW2, PW3, PW6) outlet (OW) were collected for quantification coliform by MPN technique count on TCBS agar. Coliforms...

Abstract Drinking water quality and its public health effect are ignored in urban slum households of Ethiopia. The aim this study was to assess physicochemical microbial drinking stored Hawassa City, Cross-sectional conducted a total 120 samples were collected from 60 (60 tap, households) test the quality. Wagtech Potalab + PTW − 1000 used parameters. Physicochemical parameters—temperature, tur...

Total and fecal coliform bacteria were isolated from the cloaca and feces of the estuarine diamondback terrapin. The majority of samples contained fecal coliforms. Escherichia coli was the predominant fecal coliform species isolated, and members of the genus Salmonella were isolated from 2 of 39 terrapins. Fecal coliform numbers are used to regulate shellfish harvests, and diamondback terrapins...

It has been shown that, although iodinated swimming-pool waters are usually free from coliform bacteria and enterococci, the total counts frequently become relatively high. Pseudomonas alcaligenes and Alcaligenes faecalis have been shown to account for most of these high counts. It was of interest, therefore, to compare the microbial flora of four alternately chlorinated and iodinated swimming ...

The aim of this study was to investigate the interaction between fish cage culture and sediment bacterial contamination in the area southern of Caspian Sea. For this purpose, sampling of sediment was collected in Mazandaran province (Nowshahr region) during the rainbow trout farming period at different distances (shadow, 200 and 1000 m from the cage) in 2017-2018. The results showed that in the...

OBJECTIVES To study bacterial contamination of fresh vegetables before cleaning and before serving to patients in 14 hospitals. MATERIAL AND METHOD Aerobic plate count was performed and emphasized on total viable aerobic bacteria, fecal coliform, fecal Escherichia coli and enteric pathogens in fresh vegetables including romaine lettuce, onion, parsley, celery and tomato before cleaning and be...

Theprevalence and seasonal variation of bacterial indicators of faecal pollution such as total coliform bacteria, faecal coliform bacteria, Escherichia coli and faecal streptococci were investigated in samples of water and beach sand from the four fish landing centres of Thoothukudi. Further the samples were screened for Salmonella to study the reliability of faecal indicator bacteria as an ind...

Coliform mastitis is tremendously important to the dairy industry for several reasons. First, it has become the predominant form of clinical mastitis and current management practices favor an increase in incidence. Second, coliform organisms cause some of the most severe cases of clinical mastitis. Third, as present trends in the dairy industry of increasing milk quality continue, environmental...
