The clinical isolates of Mycobacterium tuberculosis (47 ofloxacin- susceptible and 71 ofloxacin-resistant) strains obtained from individual patients from various parts of India were analyzed for gyr A mutation in quinolone resistant determining region (QRDR). Most of the mutations were seen clustered in the codons 90, 94 and 95, which is a hot spot region of QRDR. The types of mutations were correlated with the in vitro susceptibility pattern of the strains to ofloxacin. The resistance to fluoroquinolones was observed predominantly due to gyr A mutations. Gyr A being a gene with house keeping functions, is highly conserved in various mycobacterial species. It was adapted for PCR-RFLP assay using gyr A gene to see the difference in the profile of 23 standard species of mycobacteria. M.tuberculosis, M.avium, and M.intracellulare produced a different profile with two different restriction enzymes. ····· 10361119609

A virus that preys on bacteria is called a bacteriophage. The main reason to learn about virus is to shield ourselves from being infected by them in the emergence of a viral epidemic or, perhaps, to live with them accommodatingly. We learned about the existence of virus just a little more than a century ago and new facts about them keep turning up all the time. There is still a great deal that we do not know about virus. We cannot produce a vaccine against viral infections such as HIV with the same concept that led to the dicovery of the first vaccine, for Smallpox, by Janner. Whether this drawback is due to the complexity of individual virus or the continued lack of certain basic knowledge of viral nature, no one can say. This book is a collection of Tirasak`s bacteriophage research articles covering all sides of the argument concerning the bacteriophage and virus. It will be of benefit to anyone, who is interested in the interaction and relationship of bacteria and bacteriophage for further application of viral study. ····· 10361119556

Gelation is one of the major defects in UHT milk and milk products as it limits the shelf life of the product.It may frequently exhibit certain changes in the flavor and texture during Storage.Many studies have demonstrated that endogenous and bacterial proteinases play an important role in gelation of UHT milk. These enzymes are generally produced by psychrotrophic organisms that grow in milk during refrigerated storage like Pseudomonas and spore forming bacteria like Bacillus that survive heat treatment.To gain more information about the gelation phenomena in UHT milk the present study investigated the role of B. cereus and bacterial proteinases at different temperatures on the gelation of UHT milk.

However, when a rupture of the cutaneous surface occurs, staphylococci can enter the host and become pathogenic. Therefore, S. epidermidis has emerged in recent years as a major nosocomial pathogen associated with infections of implanted medical devices. Staphylococci adhere to such devices and have the ability to develop biofilms, which constitutes an important virulence factor and the most relevant pathogenic mechanism of staphylococcal infection. The work presented in this book aimed at evaluating the adhesion and biofilm formation capabilities of S. epidermidis clinical strains to biomaterials. This book, hence, covers important topics such as: the surface properties that affect initial bacterial adhesion as well as of ways to prevent it the properties of mature biofilms and the phenotypic differences between sessile and planktonic cells the assessment of cell wall and extracellular matrix proteins profiles to evaluate their importance on the process of biofilm formation, among others. ····· 10361118975

The enzyme minimizes the need for supplementation with inorganic phosphorus, due to its ability to improve the utilization of organic phosphorus in poultry and thus markedly reduces the excretion of phosphorus in manure. Two different strains (a` and b`) similar to Aspergillus species were isolated from soil by using agar plates for the production of Phytase.

IncP specific DNA sequences (trfA2 and oriT) were detected which revealed that IncP plasmids are prevalent in these Gram negative bacteria isolated from soil which was irrigated with wastewater discharged from industries. Present findings suggest the role of conjugative plasmids as contributors to maintenance and spread of adaptive traits (pesticide tolerance/metal and antibiotic resistance) in microbial communities. In this study, transconjugants isolated by exogenous plasmid isolation in biparental mating indicates that genes for the tolerance of pesticides and metals/antibiotic resistance can be distributed by conjugative plasmids in the natural environment. Our results suggest that wastewater and soil at an industrial area near a pesticide industry contained certain genotoxic agents which are capable of inducing mutations. ····· 10361118831

It is involved in cellular resistance to stress, metabolism, differentiation, aging, and tumor suppression. SIRT1-/- mice demonstrate embryonic and postnatal development defects. We examined hematopoietic and endothelial cell differentiation of SIRT1-/- mouse embryonic stem cells (ESCs) in vitro, and hematopoietic progenitors in SIRT1+/+, +/-, and -/- mice. SIRT1-/- ESCs formed fewer mature blast cell colonies. Replated SIRT1-/- BL-CFCs demonstrated defective hematopoietic potential. Endothelial cell production was unaltered, but there were defects in formation of a primitive vascular network from SIRT1-/- derived embryoid bodies. Development of primitive and definitive progenitors derived from SIRT1-/- ESCs were also delayed and/or defective. Differentiation delay/defects were associated with delayed capacity to switch off Oct4, Nanog and Fgf5 expression, decreased -H1 globin, -major globin, and Scl gene expression, and reduced activation of Erk1/2.

The higherconcentration of salts in root zone may stimulateendogenous ethylene biosynthesis in roots, whichconsequently inhibits its growth. One of the majormechanism utilized by plant growth promotingrhizobacteria (PGPR) to facilitate plant growth anddevelopment is the lowering of ethylene levels in theplant roots by deamination of1-aminocyclopropane-1-carboxylic acid (ACC), theimmediate precursor of ethylene in plants. In thegiven study, three pre-isolated bacterial strainshaving ACC deaminase activity were used forinoculation of wheat seeds. Inoculated seeds weresown in salt affected field, fertilized with NPK@120-100-60 kg ha-1, respectively. Data regardingvarious growth parameters and yield parameters wasrecorded at the time of harvesting and statisticallyanalyzed.

Induction of plant s natural defenses, such as systemic acquired resistance (SAR), is the way for management of plant viral diseases. This induction of resistance occurs through changes of some physiological mechanisms and controlling enzyme activities. Understanding the mechanisms responsible for these physiological alterations, which developed during virus infection or resistance induction, are the major current challenges in the study of plant viral disease. In the present time, host induced resistance is required to minimize the overloading economical problems occurred due to viral disease outbreaks.

Its impact far exceeds the phenomenal discoveries of antibiotics and any modern surgical advances. Beaches in the Isle of Man and Cambois in the Northeast of England were designated as sites for the study of the impacts of sewage discharges from marine outfalls on the aesthetics and bacteriological quality of beaches/bathing waters. Aesthetic studies showed beaches littered with sewage derived debris, (SDD) considerably worse after heavy rainfall. The presence of SDD such as faeces, sanitary wear, floating debris, unsightly surface slicks, and discoloration are the most important features associated in the public mind with sewage pollution. Liquid and floatable solid wastes discharged at any level under seawater rise to the surface and strong winds override tidal currents in determining their direction/dispersion. Fresh sewage discharged from marine outfalls returned to pollute the study beaches/bathing waters within three hours of discharge. Culture-based enumeration methods estimated total populations of bacteria in bathing/offshore seawater samples. Total coliform and E.coli densities in bathing water samples exceeded the UK EC mandatory standards.
