Thirty eight (25.3%) women were found to be colonized with GBS. A significant association was found to be between GBS colonization and increasing age and multi-parity. Colonization rates were significantly higher in pregnant women = 30 years and after the third pregnancy. PCR assay, latex agglutination testing and Islam medium are reliable methods to detect GBS in late pregnancy with the advantage that PCR assays and latex agglutination test when done directly on the primary broth cultures provided detection of GBS 24 h sooner than the culture method using Islam medium. Penicillin G stills to be the first choice antibiotic for the treatment of GBS infections. Resistance to cefotaxime was detected in 3 Isolates (7.89 %). Five isolates (13.15%) were resistant to erythromycin and 3 (7.89%) were intermediate. Nine isolates (23.86%) were resistant to clindamycin. ····· 1036121547

The production of exo-biopolymer by psychrotrophic bacteria and their probable role in the environment, especially in terms of heavy metal adsorption is observed. This book contains data of extensive experimental work on cold induced biopolymer production and sorption using FE-SEM, RPHPLC, HPAEC-PAD, DSC and WXRD. Adsorption isotherms and kinetic modeling were done to predict the types of sorption which were further confirmed by EDX, FTIR and chemical modification. Many biosorption studies were conducted worldwide. But no effort of establishing a model for choosing better biosorbent was observed. This is the first time a totally new model for the field of environmental biotechnology is established in this book. It can be extremely useful to screen a better biosorbent for one or several particular metals in a particular environment. From this study we can also see a new bacterium which can produce a multifunctional aminosugar and their molecular basis. ····· 1036121524

Furthermore, the study aimed to investigate the effectiveness of a combination of both treatment modalities on wound healing. LLLT is a form of phytotherapy, involving the application of low-power monochromatic and coherent light to injuries and lesions to stimulate healing. LLLT has been used in many experiments since the 1960s to examine the influence of laser radiation on the healing process of wounds. Calendula preparations are mainly used for the treatment of wounds. It is an all purpose skin-healing agent. Although only a few statistically significant differences were obtained between the measurement tools and any of the treatment protocols, it is important and worth noting that small differences in the cellular level might have a significant influence at the systemic level because of cell-cell interaction that may elicit a cascade of events. ····· 1036121491

Devices for rapid diagnosis of malaria emerged to meet the need as reliable diagnostic adjunct to microscopy in clinical settings. ParaSight-F test and QBC assay are such diagnostic methods.QBC assay involves direct observation of centrifuged blood in capillary tube, stained by acridine orange.ParaSight-F test is antigen detection in dipstick format in which a monoclonal antibody captures a specific antigen of Plasmodium falciparum (PfHRP-II, present in the parasite throughout the erythrocytic cycle) if antigen is present, a positive result is indicated by a second anti-HRP-2 antibody labeled with coloured marker, which produces visible line on dipstick. ····· 1036121249

Various foods have been implicated as sources of Salmonellosis to humans. These include poultry, eggs,pork, and fish. Although prevalence of Salmonellosis is high in Western Kenya around Lake Victoria region, no particular food source has been identified to be associated with its transmission. Fish is the main source of protein for people living around the lake. Poor sanitary facilities at fishing beaches are likely to contaminate the lake waters.

Cyanobacteria are supposed to have evolved during the Precambrian era and believed to be the first one to introduce oxygen into the initially reducing atmosphere by oxygenic photosynthesis. Reactive oxygen species (ROS) in cyanobacteria are commonly generated during normal growth and development. However abiotic and biotic stresses enhance the level of ROS which in turn pose the danger of oxidative stress. Ability to perceive ROS and to rapidly initiate antioxidant defenses is crucial for their survival. Therefore cyanobacteria evolved four lines of defense mechanisms with enzymatic and non-enzymatic antioxidants as an arsenal to cope with multiple stresses. Moreover bioinformatical methods and tools provide an insight to the in silico structure prediction of the antioxidative proteins of cyanobacterial origin. ····· 1036120787

Furthermore, there is evidence that these starvation models are not physiologically relevant compared to aging cells in batch culture. This document describes the development of a methodology for isolating RNA from aging and starving bacterial cells using organic extraction. Reverse-transcription quantitative PCR is then utilized to measure changes in gene expression for the purpose of corroborating previous microarray studies. Suggestions for isolating RNA from even older cultures are discussed as well as the limits of statistical analysis of gene expression in aging cell populations. A literature review of the small number of studies attempting to analyze starvation-induced and temporal gene expression in bacteria is also included. ····· 1036120710
