entire margin and mucoid texture. While Salmonella sp and Shigella sp both form filamentous colony and filamentous margin with dry texture. The elevation for Salmonella sp and Shigella sp colony are flat and raised respectively. Besides that‚ Pseudomonas aeruginosa form irregular colony‚ reaised elevation‚ lobate margin‚ and wet texture. Other bacteria‚ that are Serratia marcescens‚ Proteus vulgaris‚ and Klebsiella aerogenes form circular colony. For S. marcescens and K. aerogenes they have entire margin

epithelium cells in response to primary inflammatory signals. PTX3 binds with high affinity to the complement element C1q‚ the living thing matrix element TNFα induced protein 6 and chosen microorganisms‚ as well as Aspergillus fumigatus and genus Pseudomonas aeruginosa. PTX3 activates the classical pathway of complement activation and facilitates infectious agent recognition by macrophages and DCs. The transcribed PTX3 is 381 amino acids long‚ features a expected mass

isolated from garage soil – Micrococcus sp. and Pseudomonas sp. were found to be hydrocarbon degraders and these two bacteria’s were selected for the degradation test. The degradation of diesel engine oil was monitored at a five day interval up to twenty five day period‚ using gravimetric method. After 25 days of incubation period‚ Pseudomonas sp. degraded 67.57 % of the oil and Micrococcus sp. with 52.95 %. But the mixture of Micrococcus sp. and Pseudomonas sp. were found to have great potential to degrade

Multiplication of contaminant bacteria in urine and interpretation of delayed culture. Abstract A prospective study of the bacterial populations of non-infected urine was mounted in an attempt to define the length of delay between voiding and analysis during which culture would not give false positive results due to the multiplication of contaminant bacteria present at the time of voiding. The findings suggest that culture of urine within four hours of voiding is likely to give a true indication

Cystic Fibrosis is caused by a fault in the cystic fibrosis transmembrane conductance regulator (CFTR) gene on chromosome 7 at q31.2. For CF to be expressed‚ a faulty copy of the gene must be present at both alleles; autosomal recessive. Therefore both parents must be carriers of‚ or affected by the cystic fibrosis gene (fig. 1) for the gene to be passed on. If a person has one copy of the faulty allele (are heterozygous) they are carriers of the gene and can pass this allele on; if they possess
