Bacillus bacteria are advantageous antagonistic organisms that can be used as bio-control agents. This study is aimed at screening the activity of different strains isolated and molecular identification superior chitinase producer strain against dermatophytes fungi. Soil samples were collected from places Kotoor city, Gharbia Governorate, Egypt Al Madina Munawwarah, Kingdom Saudi Arabia. A coll...

The present investigation aims to the isolation of Streptomycetes from saline soil. The isolates were varied in color to aerial vegetative mycelia, morphology of conidospore surface, melanin production, utilization of carbon; nitrogen source and fatty acid analysis, as well as physical and chemical characters for their habitat soil. Streptomycetes isolates exhibiting wide range of variability. ...

Standard search techniques for DNA repeats start by identifying seeds, that is, small matching words, that may inhabit larger repeats. Recent innovations in seed structure have led to the development of spaced seeds [8] and indel seeds [9] which are more sensitive than contiguous seeds (also known as k-mers, k-tuples, l-words, etc.). Evaluating seed sensitivity requires 1) specifying a homology...

la mer caspienne est un bassin isole de type lacustre. son regime sale depend de l'influence de l'eau douce et de l'evaporation de la nappe d'eau. la masse principale des sels vient des bassins qui occupaient son auge au pliocene et au pleistocene. cependant, des la fin du pliocene (i'age apcheron), la mer caspienne formait deja un bassin d'eau saumatre. au cours d...

Trypanosoma evansi, a blood protozoan parasite causing ‘surra’ in domestic animals is widely prevalent in different parts and is of significant economic importance in livestock production. Parasitaemia is often intermittent and is not always possible to demonstrate the parasites in blood and hence diagnosis of trypanosomosis is often difficult. The present investigation has been carried out wit...

Gram-negative fecal bacterial from three longitudinal Hg exposure experiments and from two independent survey collections were examined for their carriage of the mercury resistance (mer) locus. The occurrence of antibiotic resistance was also assessed in both mercury-resistant (Hgr) and mercury-susceptible (Hgs) isolates from the same collections. The longitudinal studies involved exposure of t...

Thirty-three strains of Cryptococcus neoformans were isolated from clinical specimens, including specimens from AIDS patients in Brazil, and were classified into two serotypes; we detected 31 and 2 strains of serotypes A and B, respectively. Random amplified polymorphic DNA (RAPD) fingerprint pattern analyses of these strains of serotypes A and B showed that the patterns were similar for strain...

siah mahi, capoeta capoeta gracilis, is a predominant fish in the river systems of the south caspian sea basin. although there is evidence of the geographical divergence of this taxon, but no information is available on genetic differences within the subspecies populations. this study was designed to evaluate variation and differentiation in the tajan river and investigation shahid rajaii dam e...

Food and clinical isolates of Listeria monocytogenes recovered from four different outbreaks of listeriosis were analyzed by their PCR-based randomly amplified polymorphic DNA (RAPD) patterns to verify their causal relationships. The generation of DNA fingerprints by PCR-based RAPD analysis is a fast and sensitive method for the epidemiological tracking and identification of bacteria implicated...
