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...

Fifteen carbapenemase-producing Enterobacteriaceae isolates and 12 carbapenemase-producing Pseudomonas aeruginosa isolates were recovered from patients hospitalized between August 2011 and March 2013 at the Hospital of Infectious Disease, Cluj-Napoca, Romania. One KPC-, nine NDM-1-, four OXA-48-, and one VIM-4-producing Enterobacteriaceae isolates along with 11 VIM-2-producing and one IMP-13-pr...

The oomycete, Phytophthora infestans, is one of the most important plant pathogens worldwide. This thesis focuses on the late blight pathogen and its host, potato (Solanum tuberosum), and the interaction between these two organisms. Resistance to P. infestans was evaluated histologically, using leaves of potato cultivars with varying levels of general resistance. Preinfectional events could be ...

Macrophomina phaseolina is a serious pathogen of many crops. In the present studies, 65 isolates of Macrophomina phaseolina from different agroecological regions of Punjab and Khyber Pakhtunkhwa provinces of Pakistan were analyzed for morphological and pathogenic variability. Regardless of their geographic origins, significant differences were detected among 65 isolates in their radial growth, ...

background and objectives: pseudomonas aeruginosa possesses a variety of virulence factors that may contribute to its pathogenicity. the aim of this study was to evaluate opri , oprl and toxa genes for pcr identification of clinical p. aeruginosa . in order to find out any relation between special virulence factors and special manifestation of p. aeruginosa infections, we detected virulence fac...

The aim of this study is to investigate the antibiotic resistance patterns of methicillin resistant Staphylococcus aureus (MRSA) isolated from out patients with chronic skin ulcer in four different hospitals in Kaduna state. A total number of 292 swab samples were collected from January 2012 to January 2013 and analyzed. MRSA isolates recovered were 14 (78 %) of the total number of Staphylococc...

We investigated the population structure of 208 Candida dubliniensis isolates obtained from 29 patients (25 human immunodeficiency virus [HIV] positive and 4 HIV negative) as part of a longitudinal study. The isolates were identified as C. dubliniensis by arbitrarily primed PCR (AP-PCR) and then genotyped using the Cd25 probe specific for C. dubliniensis. The majority of the isolates (55 of 58)...

Twelve rhizobial isolates were recovered from nodules of common bean (Phaseolus vulgaris) grown in two different locations of Egyptian soils. The most effective strains for nodule formation and nitrogen fixation were selected. Strain specificity with the bean cultivars Saxa, Canoca and Giza 6 from Germany, Colombia and Egypt were studied. The strains were characterized by amplified rDNA restric...

Understanding the diversity of a pathogen is important for developing disease management recommendations. In Phytophthora root and stem rot–soybean pathosystem, P. sojae characterized into pathotypes based on ability to cause soybean genotypes that each contain different resistance Rps gene. To understand in an area, isolates may be recovered by baiting soil samples. this research, we compared ...
