This study determined the gene effects involved in inheritance of pod length and other yield-related traits relationships among crosses between two cowpea lines (TVu 2280 TVu 2027) a yard-long bean 6642) line with long pods. Plants six generations (P1, P2, F1, F2, BC1P1, BC1P2) derived from × 6642 2027 were evaluated under field conditions. Data collected on 14 yield components each cross used ...

background and objective: to evaluate extended spectrum betalactamase (esbl) positive strains of klebsiella pneumonia and escherichia coli in positive bacterial cultures. materials and methods: in this analytical cross-sectional study, between march 2006 and march 2007, 170 bacterial isolates including 133 cases of e. coli and 37cases of k. pneumonia were examined. all cases underwent double di...

OBJECTIVES To determine the frequency of resistance of Staphylococcus aureus to various antimicrobial agents, and the relationship between antimicrobial resistance of the isolates and carriage of plasmids. DESIGN A random sampling of milk and meat samples was carried out. SETTING Milk was collected from various dairy co-operative societies in Nairobi and Kiambu districts. Minced meat sample...

The variability in esterases of the entomogenous fungus Metarhizium anisopliae was determined electrophoretically on 8.5% polyacrylamide gel. Ten isolates from diverse taxonomic groups of insects were analyzed. The electrophoretic analysis showed differences and similarities between these isolates and it was possible to distinguish six different patterns. The results obtained show a great polym...

Background & objective: Beta-lactam antibiotics resistance specifically Imipenem and Meropenem, the last choices of treatment, causes fatal events in patients with P.aeruginosa infection. The aim of this study was to detect the VIM and IMP of metallo-beta-lactamase genes in 103 isolates of P. aeruginosa in two Iranian hospitals. <strong...

Since 1999 a lineage of the pathogen Cryptococcus gattii has been infecting humans and other animals in Canada and the Pacific Northwest of the USA. It is now the largest outbreak of a life-threatening fungal infection in a healthy population in recorded history. The high virulence of outbreak strains is closely linked to the ability of the pathogen to undergo rapid mitochondrial tubularisation...

Six methods for subtyping of Campylobacter jejuni were compared and evaluated with a collection of 90 isolates from poultry, cattle, and sporadic human clinical cases as well as from a waterborne outbreak. The applied methods were Penner heat-stable serotyping; automated ribotyping (RiboPrinting); random amplified polymorphic DNA typing (RAPD); pulsed-field gel electrophoresis (PFGE); restricti...

Background: The aim of this study was to compare the biofilm formation and the prevalence of biofilm-associated genes between the isolates of methicillin-resistant (MRSA) and methicillin-susceptible (MSSA) Staphylococcus aureus. Methods: In total, 209 S. aureus isolates were collected. The antibiotic susceptibility test was conducted using nine antibiotics according to the guidelines of Clinica...
