Research ArticleOpen accessIn the keywordsUnique Characteristic Features of Mycobacterium Tuberculosis in Relation to Immune SystemRajni, Laxman S. MeenaProblem statement: Tuberculosis is a leading global mortality factor which has not been effectively controlled, with 1.7 million deaths per year and 8.9 million new cases. Aerobic microbe Mycobacterium Tuberculosis H37Rv (MTB) is the causative agent of tuberculosis. Approach: It is unique among prokaryotes due to its exceptional features contributing to its survival within the hostile environment of macrophages. Results: … …American Journal of Immunology, Vol. 7, Issue 1 · 16 Aug 2011 · 17,211 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsDetermination of Adhesin Encoding Genes in Escherichia coli Isolates from Omphalitis of ChicksReza Ghanbarpour, Mahmood SalehiProblem statement: Omphalitis is one of the most common causes of mortality in chicks during the first week after hatching. Escherichia coli strains are the most common isolated bacteria from omphalitis cases of chickens. Bacterial colonization in the host cells surfaces is a critical first step in the pathogenesis of avian pathogenic Escherichia coli isolates. Thus the current study was … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 9,557 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe Proteolytic System of Candida dubliniensisLoaiza-Loeza Salomé, Parra-Ortega Berenice, Bautista-Muñoz Consuelo et al.Proteases of Candida dubliniensis have been scarcely studied, these enzymes may play an important role in nitrogen metabolism, post-translational processing, nutritional stress, dimorphism, virulence, etc. In this work, we report the presence of five different intracellular proteases and one extracellular proteolytic activity. The intracellular proteases are: aminopeptidase ycdAPE, carboxypeptidase ycdCP, dipeptidyl aminopeptidase ycdDAP, proteinases ycdPrA and ycdPrB, and extracellular protease … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 6,953 accessesView PDF Cite

InvestigationOpen accessIn the abstractComparison Analysis of Species Composition of Entomopathogenic Fungi Isolated from Bark Beetles (Coleoptera: Scolytidae)Rauza Abdukerim, Georgy Lednev, Miloš Trýzna et al.The monitoring outbreaks of bark beetles, flight activity of imago and development of larvae were conducted with pheromone traps and trap logs. We found more than 50 dead adults with symptoms white muscardine from several points under the bark. Healthy adults of Ips typographus without any pathogenic symptoms collected from pheromone traps and trap logs under bark in the forest … …OnLine Journal of Biological Sciences, Vol. 18, Issue 1 · 18 Jan 2018 · 7,596 accessesView PDF Cite

Research ArticleOpen accessIn the abstractESCHERICHIA COLI PATHOTYPES ASSOCIATED WITH DIARRHEA IN HUMAN AND DOMESTIC ANIMALSI.I. ShabanaRuminants are important reservoirs for zoonotic pathogenic E. coli. The objective of this study was to characterize pathogenic E. coli isolates from cattle and sheep linked to human illness with respect to their path types, serotypes and genotypes. E. coli O157:H7 isolated from cattle, sheep and human patients were compared for their genomic similarity by Pulsed-Field Gel-Electrophoresis (PFGE). PCR detection … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 3 · 2 Sep 2014 · 7,362 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPHENOTYPING, VIRULENCE CHARACTERISTICS OF AEROMONAS SPECIES AND THE EFFECTS OF ESSENTIAL PLANT OILS AS ANTIMICROBIAL AGENTS AGAINST PATHOGENIC ISOLATES FROM DIFFERENT SOURCESAhmed M.A. Mansour, Hoda M. Zaki, Nibal A. Hassan, Nihad A.M. El-NasharAeromonas species are increasingly recognized as enteric pathogens. Faecal samples from 20 cow, 45 sheep; 60 goat and 60 camels were examined for the presence of Aeromonas species, which was also sought in the available drinking water (55 well water and 52 drinking chlorinated tap water were also examined). Aeromonas species was isolated more frequently from goats (21.7%) than from … …American Journal of Infectious Diseases, Vol. 10, Issue 1 · 18 Jan 2014 · 8,020 accessesView PDF Cite
