Salmonella infections are one of the major global public health problems. During the last decade, antibiotic resistance and multiresistance of Salmonella spp. have increased a great deal, especially in developing countries with an increased and indiscriminate use of antibiotics in the treatment of humans and animals. This study aims to investigate and compare antimicrobial susceptibility patter...

Received at: 23/9/2014 Accepted: 11/11/2014 Streptococcus gallolyticus infection is considered an important septicemic disease in pigeons especially in squabs. In this study the pathogenicity and antimicrobial sensitivity of St. gallolyticus were searched. 141 samples of diseased and recently dead pigeons of different ages were collected and subjected to bacterial examination in order to isolat...

INTRODUCTION Acute respiratory tract infections are the most common diseases of childhood. A preschool child suffers up to 5-7 infections of upper airways during a year. Upper airway infections make 80-90% of all respiratory infections. ETIOLOGY AND TREATMENT In 75% of all cases respiratory infections are of viral etiology, 15% of bacterial and 10% are caused by mycoplasma, rickettsiae, fungi...

Inhibitors of the energy metabolism, such as sodium azide and valinomycin, render yeast cells completely resistant against the killing action of a number of cationic antimicrobial peptides, including the salivary antimicrobial peptide Histatin 5. In this study the Histatin 5-mediated killing of the opportunistic yeast Candida albicans was used as a model system to comprehensively investigate th...

Background.  Escherichia coli is a highly clonal pathogen. Extraintestinal isolates belong to a limited number of genetically related groups, which often exhibit characteristic antimicrobial resistance profiles. Methods.  We developed a rapid clonotyping method for extraintestinal E coli based on detection of the presence or absence of 7 single nucleotide polymorphisms (SNPs) within 2 genes (fu...

Article history: Received on: 07/10/2015 Revised on: 11/11/2015 Accepted on: 06/12/2015 Available online: 26/01/2016 Objectives: To study the changing pattern of antimicrobial resistance of Escherichia coli isolates from patients of urinary tract infections over last three years Materials and Methods: A retrospective, record based study carried out based on the records of Culture and sensitivit...

The phenomenal increase in antibiotic resistant bacterial pathogens calls for regular review of antimicrobial sensitivity pattern among bacteria of clinical significance in an environment. This study was conducted to determine the common clinically significant bacterial pathogens in this environment and their antimicrobial susceptibility pattern. Bacterial pathogens isolated from various clinic...

Four flocks of Layer breeders, consist of 28000 (7000 birds each) at 25 weeks of age, hatchery and one day old chicks were subjected to swab sampling in order to isolate Staphylococcus aureus during the period from May till June 2008. Results revealed that more than half of the overall swab samples were positive (52.04%). Different isolation rates were recorded between four flocks, ranging from...

Infectious diseases are one of the most common causes of morbidity and mortality and the spread of resistant microorganisms is playing a significant role in this regard. The purpose of this study was to assess the trend in antimicrobial resistance of gram-positive bacteria at the main referral teaching hospital in Tehran during a 4-year period. All patients' biological isolates such as blood, u...
