giardia duodenalis is globally recognized as an important zoonotic intestinal protozoan parasite. so far, eight assemblages of g. duodenalis (a-h) have been identified. substantial evidence suggests the zoonotic potential of assemblages a, b, and e in livestock. in this study, the genotype of giardia duodenalis isolates was genetically identified by determining the sequence of ssu-rrna gene and...

Thalassemia is the most common hemoglobin disorder in the world and thalassemia major and intermedia stand among the most severe forms. Due to recent improvements in treatment, patients with thalassemia have longer life expectancies; hence it is of utmost importance to pay careful attention to their quality of life together with life expectancy. This study was conducted to assess the quality of...

Objectives: Resistance to third generation cephalosporins in E. coli and K. pneumoniae are due to various factors. The present study was undertaken to detect resistance mediated by ESBL’s. Multidrug resistance in isolates producing ESBL was also studied. Methods: The study included a total of 200 clinical specimens which include 95 urine, 45 pus, 32 sputum, 11 blood, 9 throat swabs, 6 suction t...

Cecal samples from laying chickens from 25 farms with a history of decreased egg production, diarrhea, and/or increased feed conversion ratios were examined for anaerobic intestinal spirochetes of the genus Brachyspira. Seventy-three samples positive in an immunofluorescence assay for Brachyspira species were further examined using selective anaerobic culture, followed by phenotypic analysis, s...

UNLABELLED Thalassemias are the most common genetic disorder on a wordwide basis. β-thalassemia is a severe hemolytic anemia which results from genetic defects in the synthesis of the hemoglobin β-chain. Various endocrine abnormalities have been described in patients with thalassemia major. Endocrine disturbances have also been observed in patients with thalassemia intermedia (TI). In this stud...

Yersinia enterocolitica strains of serotypes lethal to mice have been reported previously to produce an endogenous siderophore. In this study, an ethyl acetate-extractable siderophore was characterized and given the name yersiniophore. Yersiniophore was produced by 16 of 16 human isolates of serotypes O:4, O:4,32, O:8, O:21, and one nonhuman isolate of serotype O:21. It was not produced by isol...

Strains of extended-spectrum beta-lactamase-producing Klebsiella pneumoniae (ESBL-KP) have emerged worldwide. Concomitant ciprofloxacin resistance with ESBL production in K. pneumoniae isolates would severely restrict treatment options. Among 39 (18.5%) of 211 ESBL-KP isolates resistant to ciprofloxacin (MIC, >/=4 micro g/ml), 37 (95%) were high level resistant (MIC, >/=16 micro g/ml). These is...

Ninety-nine penicillin-sensitive Streptococcus pneumoniae strains of common pediatric serogroups/types (6, 7, 14, 19, and 23) cultured from the blood of children with invasive disease (n = 49) or asymptomatic oropharyngeal carriage (n = 50) were analyzed by multilocus enzyme electrophoresis and ribotyping; 53 distinctive multilocus enzyme genotypes (ETs) and 53 ribotypes were identified. Multil...

This study was carried out to detect the distribution of antibioticresistant genes in multi-antibiotic resistant bacteria isolated from Saudi Arabian patients in Taif city. Hence, simple methods were followed herein to isolate and characterize the antibiotic resistant bacteria by the common phenotypic, morphological, biochemical and molecular characters. Out of 200 cultures tested, 60 multidrug...
