The prevalence and mechanisms of antibiotic resistance of Helicobacter pylori have not yet been investigated in Uruguay. The objective of this study was to assess the susceptibility of H. pylori to the most frequently used antibiotics and to determine the mechanism of resistance to clarithromycin. Seventy-nine isolates were obtained from gastric biopsies of 50 adult patients during two periods,...

Clinical specimens from dogs, cats, and horses were examined for the presence of obligate anaerobic bacteria. Of 4,018 specimens cultured, 368 yielded 606 isolates of obligate anaerobic bacteria (248 from dogs, 50 from cats, and 308 from horses). There were 100 specimens from 94 animals from which only anaerobes were isolated (25 dogs, 8 cats, and 61 horses). The most common sites tested were a...

OBJECTIVE To evaluate Helicobacter pylori resistance to amoxicillin, clarithromycin, metronidazole and tetracycline in Mashhad, Iran. METHODS The cross-sectional study was done from January to May 2008 in Mashhad, involving 185 patients who had been indicated for endoscopy and lesions had been found. Biopsy samples were assessed with histological evaluation, rapid urease test, and culture. An...

OBJECTIVES Helicobacter pylori-associated infection is common in South Africa, as in other developing countries. Antibiotic resistance is recognised as a major cause of treatment failure. We studied the susceptibility and resistance patterns of H. pylori to guide empiric treatment and prevent the emergence of resistance. METHODS Two hundred H. pylori strains obtained from gastric biopsies of ...

In this study, 150 isolates of Uropathogenic Escherichia coli (UPEC) strains have been collected from different major hospitals in Kurdistan region and showed high resistant rates to most tested antibiotics accounting for 98%. There was no isolate that had demonstrated sensitive to all antibiotics, but they manifested with a wide range of resistance to most tested antibiotics ranging from resis...

Multidrug resistance is a challenge across different types of microorganisms, bacterial and viral pathogens. This is because they account for a significant outcome of clinical infections observed. The tendency of microorganisms to acquire and disseminate resistance genes among themselves via horizontal gene transfer makes resistance patterns to become widely distributed. Bacterial pathogens exh...

Introduction Urinary tract infection (UTI) is one of the most common infections in childhood. Appropriate treatment of UTI requires to knowledge about antibiotic resistance patterns of common uropathogens. The aim of this study was to determine demographic, symptoms, signs and antibiotic resistance pattern in admitted infants with clinically diagnosis of UTI in 17 Shahrivar Hospital of Rasht Ma...

BACKGROUND Antimicrobials have been useful in the treatment of H. pylori-related dyspeptic diseases. However, emergence of resistant strains often decreases the eradication rates of H. pylori infections. Large-scale use of antimicrobials will lead to the diminishment of susceptible strains while allowing resistant survivors to outgrow and spread resistance genes. The aim of this study was to as...

A mathematical model is presented for the increase and decrease of non-inherited antibiotic resistance levels in bacteria. The model is applied to experimental data on E. coli exposed to amoxicillin or tetracyclin in different concentrations. The parameters of the model are estimated using a Monte Carlo Markov Chain method. The model accurately describes build-up and decline of antibiotic resis...
