Changing trends in frequency and antimicrobial susceptibility of pathogens causing catheter related infections in children

Catheter-related infections (CRIs) by bacterial pathogens are the frequent cause of nosocomial infections in hospitalized pediatric patients. The undertaken study was carried out at two different time duration in 2005 and 2011 to determine the changing trend in bacterial pathogens isolated from catheters and their antimicrobial susceptibility in children. Patients implanted with endotracheal tube (ETT), peritoneal...

Effects of selected herbicides on soil microbial populations in oil palm plantation of Malaysia: A microcosm experiment

Herbicides are commonly used in Malaysia to control weeds in oil palm plantation. In addition to their impact on weeds, these herbicides are also affecting soil microorganisms which are responsible for numerous biological processes essential for crop production. In the present study, we assessed the impact of four commonly used herbicides (paraquat, glyphosate, glufosinate-ammonium and metsulfuron-methyl) on soil...

Influence of effective microorganisms and green manure on soil properties and productivity of pearl millet and alfalfa grown on sandy loam in Saudi Arabia

A field experiment was conducted to study the effect of effective microorganisms and green manure on soil properties and yield of pearl millet (Pennisetum glaucum (L.) R. Br.) and alfalfa (Medicago sativa L.) grown on sandy loam soil under arid conditions at Agriculture Experimental Station of King Abdulaziz University (KAU), Hada Alsham, Saudi Arabia. Four treatments were investigated. In control (T1), the...

Chemical composition, antimicrobial activity and antioxidant capacity of some medicinal and aromatic plant extracts

In this study, the chemical composition, antimicrobial activity and antioxidant capacity of essential oils obtained from oregano (Origanum onites L.), sage (Salvia triloba L.), mint (Mentha piperita L.), and laurel (Laurus nobilus L.) were determined. The essential oil components were identified by gas chromatography (GC) analysis. The antimicrobial activity of the oils was determined...

Resistance patterns and detection of resistance genes in Escherichia coli isolated from diarrheic calves in Northeastern China

  The aim of this study was to investigate the antimicrobial resistance and to characterize the implicated genes in Escherichia coli isolated from diarrheic calves during 2008-2011. A total of 104 samples were tested to 15 antimicrobial agents with disk-diffusion method.High resistance to amoxicillin, streptomycin,...

Characterization of egg yolk immunoglobulin (IgY) against enterotoxigenic Escherichia coli and evaluation of its effects on bovine intestinal cells

Enterotoxigenic Escherichia coli (ETEC) infection is common in calves. Egg yolk antibodies (IgY) have been used to treat gastrointestinal infectious diseases. This study aimed to characterize IgY against bovine ETEC and to evaluate its effects on bovine intestinal cell culture challenged with a bovine ETEC strain. IgY was isolated from the egg yolks of hens immunized with ETEC. The characteristics of IgY...

Phylogenetic and pathogenetic analysis of Streptococcus suis serotype 7 strain HW07 isolated from diseased pig in China

A recent isolate of Streptococcus suis serotype 7 (SS7), named HW07, was isolated from brains of pigs suspected with Streptococcus suis (S. suis) infection. The sequence types (ST) of this isolate was determined by Multilocus sequence typing (MLST) method. In order to evaluate pathogenesis of HW07 isolate, zebrafish and pigs were inoculated with HW07 strain by peritoneal cavity and vein. The...

Isolation and identification of Escherichia coli O157:H7 from ground beef hamburgers in Khuzestan Province, Iran

Meat products have been implicated in outbreaks of E.coli O157:H7 in most of the world. This bacterium is associated with diseases such as hemorrhagic colitis, hemolytic uremic syndrome and thrombotic thrombocytopenic purpura. In this study, we used two Conventional methods and Multiplex PCR for the isolation and identification of E. coliO157:H7 from ground beef hamburger...

Antioxidant and antibacterial activities of leaves and branches extracts of Tecoma stans (L.) Juss. ex Kunth against nine species of pathogenic bacteria

Tecoma stans of the Bignoniaceae family, is an important medicinal plant. Different extracts of the leaves and branches of T. stans were evaluated as antibacterial potential against the growth of some human bacterial strains using the disc diffusion and minimum inhibitory concentration (MIC) methods as well as the antioxidant activity by 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. Total...
