Research ArticleOpen accessEvery word in the titleCorrelation Between in vitro Biofilm Formation and Virulence Properties of Extra-Intestinal Pathogenic Escherichia Coli (Expec)Md. Fakruddin, Khanjada Shahnewaj Bin Mannan, Reaz Mohammad MazumdarAbout 65 Escherichia coli strains isolated from extra-intestinal sites were included in this study to determine their biofilm formation capability and virulence properties. About 87% ExPEC isolates were motile and 12.3% were found to be non-motile. Only 12.30% isolates were strong biofilm former (SBF >1.5) whereas 18.46% isolates were non biofilm former. About 71% isolates were capable to express curli … …OnLine Journal of Biological Sciences, Vol. 14, Issue 4 · 14 Jan 2015 · 6,942 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePHENOTYPING, 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 PDFCite
Research ArticleOpen accessEvery word in the titleSELECTION OF BEAUVERIA BASSIANA (BALSAMO) VUILLEMIN ISOLATES FOR MANAGEMENT OF MYZUS PERSICAE (SULTZAR) (HOM.: APHIDAE) BASED ON VIRULENCE AND GROWTH RELATED CHARACTERISTICSMohammad S. Al-alawi, Maher ObeidatIsolates of the entomopathogenic fungus Beauveria bassiana originated from Jordan were evaluated for their efficacy against the green peach aphid, Myzus persicae under laboratory and greenhouse conditions. Efficacy evaluation involved testing all isolates at a concentration of 1×107 conidia/mL followed by concentration dependent and greenhouse bioassays for the top virulent isolates. Growth characteristics related to virulence were evaluated for high, … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 28 Dec 2013 · 7,943 accessesView PDFCite
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 PDFCite
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 PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractPCR Diagnosis for the Identification of the Virulent Gene of Salmonella in Poultry MeatD. K. Zhanabayeva, A. Y. Paritova, G. K. Murzakaeva et al.The purpose of this study was to conduct microbiological studies of poultry meat imported into Mongolia and establish the serotypes and plasmids of Salmonella and determine the virulence of the gene encoding antibiotic resistance and its transmigratory properties. The PCR molecular biological method was used and according to the results, Salmonella enteritidis was identified in chicken carcasses of the American … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 27 Aug 2021 · 6,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular-Biological Properties of the Attenuated Strain of Salmonella Abortus-Equi E-841, used in the Creation of a Vaccine against Abortion of MaresAssiya Mussayeva, Natalya Yegorova, Merey Yerishov et al.Salmonella abortion of mares takes a leading place in the in factious pathology of horses and leads to the abortion of pregnant mares and infected stallions become salmonella carriers. The disease with salmonella abortion manifests itself in the last months of pregnancy, maybe-during the mass foal of mares-in the spring.

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 PDFCite
Research ArticleOpen accessIn the abstractIsolation, Identification and Genomic Analysis of Plesiomonas shigelloides Isolated from Diseased Percocypris pingi (Tchang, 1930)Lei Pan, Shuiyi Liu, Xuwei Cheng et al.Recently, the outbreak of a serious infectious disease of unknown etiology was noted in Percocypris pingi (Tchang, 1930) farms in Yunnan province. Due to currently limited information, we aimed to identify the pathogen isolates, determine the susceptibility of the isolates, evaluate the pathogenicity and analyze the genome of the representative strain. Ten strains of Gram-negative rods were isolated from diseased … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 22 Dec 2017 · 8,836 accessesView PDFCite
