Antibiotic resistance patterns, characteristics of virulence and resistance genes and genotypic analysis of serotypes recovered from different sources.

The present study evaluated the isolates obtained from various origins in Iran. strains previously recovered and stored in the veterinary microbiology laboratory were serotyped and subjected to antibiotic susceptibility test, detection of the virulence and resistance genes by polymerase chain reaction (PCR), and genotyping by enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR). All isolates showed resistance to erythromycin and the most resistance rates were detected for trimethoprim (86.

Avian polyomavirus (APV) infection causes various health problems in psittacine species, including death. The present study was conducted to investigate the prevalence of APV among psittacine birds in Iran. We also aimed to evaluate the impact of age, sex, species, season, and origin of the birds on the prevalence of APV.

Study on antibiotic resistance and phylogenetic comparison of avian-pathogenic (APEC) and uropathogenic (UPEC) isolates.

Avian pathogenic (APEC) and uropathogenic (UPEC) can cause vast infections in humans and poultry. The present study was conducted to compare the isolates of the APEC and UPEC pathotypes on the basis phenotypic and genotypic features of antibiotic resistance and phylogenetic differences. Total number of 70 identified strains, including 35 APEC and 35 UPEC isolates, were isolated from avian colibacillosis and human urinary tract infection (UTI), and were subjected to the antimicrobial susceptibility testing, polymerase chain reaction (PCR) detection of the resistance genes, phylogenetic grouping and DNA fingerprinting with enterobacterial repetitive intergenic consensus PCR (ERIC - PCR) to survey the variability of the isolates.

Antibiotic resistance and phylogenetic comparison of human, pet animals and raw milk Staphylococcus aureus isolates.

The present study was conducted to compare the S. aureus isolates from different sources in the basis of resistance phenotypic and genotypic features and phylogenetic differences. Total of 70 S.

Antimicrobial resistances, and molecular typing of Campylobacter jejuni isolates, separated from food-producing animals and diarrhea patients in Iran.

The aims of this study were to regain new epidemiology information about frequency, drug resistance rates, and typing of Campylobacter jejuni (C. jejuni) isolates, obtained from some poultry and cattle farms, slaughterhouses, and people with diarrhea. In this regard, Minimal Inhibitory Concentration (MIC) of several antibiotics and the associated antibiotic resistance genes, including tetO, tetA, cmeB, and bla were evaluated.

Prevalence and antibiotic resistance pattern of bacteria isolated from urinary tract infections in Northern Iran.

Background: This study aimed to investigate the bacteria associated with urinary tract infection (UTI) and antibiotic susceptibility pattern of the isolates during 2013-2015 in Northern Iran.

Materials And Methods: Overall 3798 patients with clinical symptoms of UTI were subjected as samples, and they were cultured and pure isolated bacteria were identified using biochemical tests and subjected to antibiogram assessment using disc diffusion method.

Results: Totally, 568 (14.

Antimicrobial Resistance and Virulence-Associated Genes of Campylobacter spp. Isolated from Raw Milk, Fish, Poultry, and Red Meat.

This study was designed and conducted to evaluate the frequency, antimicrobial resistance, and presence of six virulence-associated genes among thermophilic Campylobacters isolated from raw milk, poultry (chicken, turkey, and duck), fish, cattle, and sheep meat. Out of 590 samples, which were recovered from different origins, 141 (23.9%) samples were positive for Campylobacters.

Prevalence and antibiotic resistance profile of thermophilic spp. of slaughtered cattle and sheep in Shiraz, Iran.

Although poultry meat is considered as the main source for human infections, there is limited information about non-poultry sources. The present study was aimed to investigate the prevalence and the antibiotic resistance of thermophilic spp. in fecal samples of the cattle and sheep in Shiraz, Iran.

Inhibitory effect of Zataria multiflora Boiss. essential oil, alone and in combination with monolaurin, on Listeria monocytogenes.

Listeria monocytogenes is one of the major causes of infections in developing countries. In this study, chemical composition and anti-listerial effect of the essential oil of Zataria multiflora Boiss. alone and in combination with monolaurin were evaluated at different pH values (5, 6, and 7) and temperatures (5 ˚C and 30 ˚C).

Occurrence and antimicrobial resistance of emergent Arcobacter spp. isolated from cattle and sheep in Iran.

This study is conducted to determine the occurrence and antimicrobial resistance of Arcobacter spp. isolated from clinically healthy food animals. A total of 308 samples from cattle (200) and sheep (108) were collected from Shiraz slaughterhouse, southern Iran to investigate the presence of the important Arcobacter spp.

Genetic Characterization of Campylobacter Jejuni and C. coli Isolated From Broilers Using flaA PCR-Restriction Fragment Length Polymorphism Method in Shiraz, Southern Iran.

Background: Thermophilic campylobacters, particularly Campylobacter jejuni and C. coli are the main agents of human campylobacteriosis. Campylobacter contaminated chicken products is the most important source of foodborne gastroenteritis.

Tetracycline Resistance Genes in Campylobacter jejuni and C. coli Isolated From Poultry Carcasses.

Background: Campylobacter is one of the leading bacterial species causing foodborne illnesses in humans. Antimicrobial agents have been extensively used for treatment of Campylobacter infections; but in the recent years, both animal and human isolates of this bacterium have shown resistance to several antibiotics such as tetracycline.

Objectives: The aim of this study was to investigate the presence of genetic determinants of tetracycline resistance in Campylobacter spp.

Association of Three Plasmid-Encoded spv Genes Among Different Salmonella Serotypes Isolated from Different Origins.

The virulence plasmid associated Salmonella plasmid virulence (spv) locus is strongly concomitant with strains that cause non typhoid bacteremia. The spv region contains three genes required for the virulence, the positive transcriptional regulator spvR and two structural genes spvB and spvC. The purpose of this study was to investigate the presence of these three genes among salmonella serotypes isolated from different sources.

Correlation between distribution of muscle weakness, electrophysiological findings and CTG expansion in myotonic dystrophy.

Myotonic dystrophy type 1 (DM-1) is a multi-system disorder affecting the muscles, brain, cardiovascular system, endocrine system, eyes and skin. Diagnosis is made by clinical, electrodiagnostic and genetic studies. This study aimed to determine the correlation between CTG expansion and distribution of muscle weakness and clinical and electrophysiological findings.

Occurrence of six virulence-associated genes in Arcobacter species isolated from various sources in Shiraz, Southern Iran.

In humans, arcobacters are associated with watery diarrhea and septicemia. Although, recently, more cases of diarrhea have been caused by Arcobacter species, very little is known about its pathogenesis. Therefore, the aim of this study was to evaluate the presence of six putative Arcobacter virulence genes (cadF, ciaB, cj1349, mviN, pldA, and tlyA), in a set of 113 Arcobacter butzleri, 40 Arcobacter cryaerophilus, and 15 Arcobacter skirrowii isolates that were recovered from various origins.
