Culture-based and genomics methods provide different insights into the nature and behavior of bacteria. Maximizing the usefulness of both approaches requires recognizing their limitations and employing them appropriately. Genomic analysis excels at identifying bacteria and establishing the relatedness of isolates. Culture-based methods remain necessary for detection and enumeration, to determin...

Investigating genetic diversity in plant species provides a platform for further insight in plant breeding and conservation. Therefore, in the present study genetic diversity of 13 geographically isolated genotypes of Zhumeria majdea, as a seriously endangered medicine plant growing exclusively in Hormozgan province (South of Iran) was studied. To do so, the leaf samples of Z. majdea were colle...

Background and Purpose: Cladosporium species are ubiquitous, saprobic,dematiaceous fungi, only infrequently associated with human and animal opportunisticinfections. Materials and Methods: Airborne samples were collected using the settle plate method, and soil samples were obtained from a depth of 5-10 cm of the superficial soil layer. Samples were cultured on Sabouraud dextrose agar (SDA) pla...

Background: Cholesterol oxidase (CHO) has various clinical and industrial applications. Recently, microbial CHO have received a great attention for their wide usage in medicine. Here, taxonomic characterizations of isolated strain from soil, optimization of the conditions for CHO production and biochemical characterizations of produced CHO enzyme were described. Finally, CHO gene was cloned int...

Typhoid disease or salmonellosis is a common sickness in horses. In several epidemiological studies inhospitalized horses, several serotypes of Salmonella often are predominant in nosocomial infections.Transportation, overcrowding, dehydration, oral antimicrobial therapy and infections are the risk factorswhich may activate latent or subclinical salmonellosis. In this study, t...

abstract: cryptosporidium parvum is an apicomplexan protozoan parasite which causes diarrhea in both human and wide range of animals. since this protozoa causes remarkable economic losses in cattke industry in iran, the molecular determination of porotozoa and characterization of its protein pattern and immunogenic antigend are the aim of this study. in this study, diarheatic fecal samples of c...

The assessment of genetically modified (GM) crops for regulatory approval currently requires a detailed molecular characterization of the DNA sequence and integrity of the transgene locus. In addition, molecular characterization is a critical component of event selection and advancement during product development. Typically, molecular characterization has relied on Southern blot analysis to est...

Background:Urinary Tract Infections (UTIs) are the most common infectious diseases in childhood. The Uropathogenic Escherichia coli (UPEC) strains account for as much as 80% of UTIs. Objective:From a clinical perspective, it is important to know which virulence factors and antibiotic resistance properties are present in UPEC strains in pediatrics. Therefore, this study was carried out...

Studies on earthworms using molecular markers are rare in Africa except a handful from South Africa. Reports on Libyodrilus violaceous,an earthworm found in West Africaare available including their metal tolerance and bioaccumulation capacity but their molecular characterization and ecotoxicology studies are scarce. In this study, triplicate L. violaceous specimens were collec...

Rice, (Oryza sativa L. 2n=24) belongs to the family Gramineae and subfamily Oryzoideae. Oryza has two cultivated species: glaberrima. Breeding for good-quality traits requires selection of parents with a wider genetic diversity. Molecular markers are used in molecular biology biotechnology identify sequence DNA. have played an increasing role rice breeding cultivar improvement, screening, selec...
