Background: The antimicrobial resistance is one of the most serious and expanding health problems world -wide in the last decades. The esbl escherichia coli. (extended – spectrum beta-lactamase e.coli) represents an important aspect of it .Objectives: To get an overview on the esbl e.coli prevalence profile in general. Also to assess the antibiotic sensitivity of esbl e. coli trying to specify the most effective antibiotics in combating this micro-organism.Methods: this study tries to focus on this problem in Iraq which through a prospective study approach by taking 35 clinical samples from various sources (urine, blood, abscess, eye ,vagina ,stool and others),and after confirming the presence of e.coli, the presence of esbl e.coli and antibiotic sensitivity are confirmed by the use of Kirby - bauer method.Results: results showed that esbl e.coli constitutes 80% of the cases, while the results of antibiotic sensitivity were as follows: ampicillin 3.3% , ampicillin/sulbactam 20% , amoxi/clav 0%pipracillin/tazobactam 89.7% meropenem 96.7% ,imipenem 96.9% ,cefotaxime 0% ,ceftriaxone 11.8%,ceftazidime 16.1%,cefipime 14.3% ,cefazolin 16.1% cefoxitin 64.7%, aztreonam 14.3%,gentamycin 50% ,tobramycin 64.3%, amikacin 94.3%,ciprofloxacin 58.8% ,levofloxacin,64.5%nitrofurantoin,79.2%,trimethprimesulphamethoxazole 29.6% .Conclusion: the problem of esbl e.coli is expanding and there is a continuous demand for frequent monitoring of the new trends on antimicrobial resistance in different parts of the world in addition to trying to develop new antimicrobials to combat the new highly resistant strains .moreover there is a continuous need to educate the medical and the paramedical staff abot the risk of unjustified and improper prescription and use of antimicrobials.Key words: escherichia coli, extended-spectrum beta-lactamase, kirby-bauer method, muller hinton agar
Objective:The current study aime to isolate Escherichia colifrom urinary tract infections(UTIs) in many Baghdad hospitals. The study concentrate on phylogenic groups and this was done based on triplex PCRmethod by primers besieged to three genetic markers, chuA, yjaA and TspE4.C2. Evaluate the relationship of phylogenic groups of E. coli isolates with the antibiotic-non sensitive patterns. Methodology:Four hundredof E.coli bacteria isolated from urine samples from five hospitals in Baghdad city include: Ghazi AL-Hariri, Ibin- Al-Beledi , AL-Iskan , AL-Nooman and AL-Yarmoke hospitals. Phylogenetic categorizatio
Toxoplasma gondii is intracellular parasites, which infect a large proportion of the world's population, but uncommonly causes clinically significant disease .The present study was performed to estimate the prevalence of toxoplasmosis in Iraqi male. Venous blood samples were collected from healthy male age between (18-57) years attended the National blood transfusion centre in Baghdad from Oct, 2011 to Jan. 2012. Latex agglutination test (LAT) and Enzyme linked Immunosorbant Assay (ELISA), were used to detect anti-Toxoplasmosis IgM and IgG antibodies. The results showed significant differences between seropositive toxoplasmosis infections between LAT, 136/400 (34%) and ELISA - IgG, 121/400 (30.25%). The blood group phenotypes of the infe

Follow up was conducted after one day, 7 days, 14 days, one month, and finally 3 months postoperatively. The study lasted for 1.5 year. Surgical diode laser with wavelength of 810 ± 20 nm, with two power levels of 10 and 15 W were used in contact and in non-contact mode via optical fiber. The postoperative outcome revealed; greater haemostatic capability, dry, sealed wound and noticeable lack in pain sensation
Extensive studies have been conducted on the microbial properties of Streptococcus pneumoniae all over the world ,but there are few studies in Iraq on the most important factors of virulence possessed by S.pneumoniae isolates found in Iraq , 195 of sputum specimens were collected from patients with pneumonia acquired from the community who were clinically diagnosed by specialized doctors depending on symptoms and Radiography of Chest . Eighteen isolates of S.pneumoniae were diagnosed by special traditional methods that used in the phenotypic identification . All isolates 18 (100%) have been given positive results for the optochin test , bile solubility test
... Show MoreCyanobacteria are prokaryotic photosynthetic communities which are used in biofertilization of many plants especially rice plant. Cyanobacteria play a vital role to increase the plant's ability for salinity tolerance. Salinity is a worldwide problem which affects the growth and productivity of crops. In this work three cyanobacteria strains (Nostoc calcicola, Anabaena variabilis, and Nostoc linkia) were isolated from saline soil at Kafr El-Sheikh Governorate; North Egypt. The propagated cyanobacteria strains were used to withstand salinity of the soil and increase rice plant growth (Giza 178). The length of roots and shoot seedlings was measured for seven and forty days of cultivation, respectively. The results of this investigation showed

Show MoreThis study includes the preparation of the ferrite nano ferrite CuxAl0.3-XNi0.7Fe2O4 (where: x = 0, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3) M using the auto combustion method (sol-gel), and citric acid was used as fuel for auto combustion. The ferrite samples were checked by X-ray diffraction (XRD), Field Emission Scanning Electron Microscopes (FE-SEM), and energy dispersive X-ray analyzer (EDX). They showed that the prepared compound has a face-centered cubic structure (FCC). The lattice constant increases with an increase in the percentage of doping of the copper ions, and a decrease for the aluminum ion and that the compound is porous and its grains are spherical, and there are no other
... Show MoreNanocrystal-ZnS-loaded graphene was synthesized by a facile co-precipitation route. The Graphene was affected on the characterization of ZnS which has been investigated. XRD results reveal that ZnS has a cubic system while the hexagonal structure has been observed by loading graphene during preparation ZnS. D.c-conductivity proves that ZnS and ZnS/Gr have semiconductor behavior. The sensing properties of ZnS/Gr against NO2 gas were investigated as a function of operating temperature and time under optimal condition. The sensitivity, response time and recovery time were calculated with different operating temperatures (100, 150, 200)oC.
This study investigates in vitro biofilm production. Presence of ica A and D genes in methicillin-resistant Staphylococcus aureus was evaluated for biofilm production by the microtiter plate method. Between December 2020 and October 2021, out of 215 clinical specimens were collected from patients with pulmonary fibrosis, pneumonia, bacteremia, chronic burns, deep wounds, urinary tract infection and catheterized patients. Out of which 45 MRSA isolates were identified by the susceptibility test utilizing cefoxitin and the occurrence of mecA gene for resistance for this antibiotic verified by polymerase chain reaction technique. A sensitivity test was conducted for five other antibiotics
