From May 2004 to October 2006, a prospective study was carried out in Dakar, Senegal, to update information about the antimicrobial susceptibility of Shigella spp. isolated from stool specimens. Among the 165 non-duplicate strains collected, 81 (49%) were identified as Shigella flexneri, 75 (45%) as Shigella sonnei, 5 (3%) as Shigella boydii, and 4 (2%) as Shigella dysenteriae. Disk diffusion t...

the present study was conducted to investigate antimicrobial resistant pattern of escherichia coli (e. coli) strains isolated from clinical specimens of jordanian pediatric patients during the period from january to december 2008. a total of 444 e. coli strains were isolated from clinical specimens and tested for their susceptibility to different antimicrobial drugs. overall, high resistance ra...

In recent years, the level of resistance of S. pneumoniae to beta-lactam and/or macrolides has increased around the world including some countries in South America. Because of this resistance, it is necessary to test the therapeutic alternatives for treating this pathogen, including the newer quinolones. This study was carried out in order to compare the in vitro activity of fluoroquinolones ga...

BACKGROUND Inappropriate use of antibiotics for non-severe upper respiratory tract infections (URTIs), most of which are viral, significantly adds to the burden of antibiotic resistance. Since the introduction of pneumococcal conjugate vaccines in 2009 in South Africa, the relative frequency of the major bacterial pathogens causing acute otitis media (AOM) and acute bacterial rhinosinusitis (AB...

INTRODUCTION Helicobacter pylori resistance to antibiotics is steadily increasing and multidrug-resistant strains are common and difficult to eliminate, mainly in countries where bismuth, tetracycline, furazolidone, and rifabutin are unavailable. AIM To evaluate the efficacy and safety of a triple therapy with proton-pump inhibitor (PPI), amoxicillin, and doxycycline in patients with multidru...

conclusions considering the high prevalence of esbl genes (bla ctx-m, 87%; and bla tem, 82%), fluoroquinolones may be used as an alternative drug in treatment, although resistance to this family is increasing as well. as a result, this increasing trend should be prevented using appropriate guidelines for prescription. background escherichia coli is the most important as well as the most common ...

OBJECTIVES The outer membrane protein M35 of Moraxella catarrhalis is an antigenically conserved porin. Knocking out M35 significantly increases the MICs of aminopenicillins. The aim of this study was to determine the biological mechanism of this potentially new antimicrobial resistance mechanism of M. catarrhalis and the behaviour of M35 in general stress situations. METHODS PCR using m35-sp...

Metal (II) complexes of Co, Ni, Cu and Zn with Amoxicillin derivative (L) were synthesized identified by elemental analysis CHNS Uv-Vis, FTIR, TGA, metal AA, magnetic susceptibility conduct metric measurement. the ligand behaves as a bidentate. All that have nickel, copper , cobalt zinc ions proposed octahedral geometry shape. Protection study corrosion behavior carbon steel surface was conduct...

BACKGROUND Most urinary tract infections (UTI) are caused by Escherichia coli. Integrons have an important role in distributing antibiotic resistance genes among bacteria. OBJECTIVES The aim of this study was to investigate the presence of class 1, 2 and 3 integrons and their association with antibiotic resistance in E. coli isolated from patient with UTI in Yasuj, Iran. PATIENTS AND METHOD...

Abstract: Multidrug resistance (MDR) bacterial infection is the next pandemic waiting behind COVID-19 with annual mortality rate 700000 worldwide. Among MDR bacteria, Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterococcus faecium and faecalis are showing average of 50 to 80% ampicillin, amoxicillin, third-generation cephalos...
