conclusions l. innocua is not a pathogen, but the presence of the bacterium could be an indicator of probable contamination with l. monocytogenes. moreover, there is a potential risk to public health from the consumption of raw or undercooked burgers, which may increase the possibility of the acquisition of resistance to antibiotics. objectives the aim of this study was to evaluate the occurren...

conclusions with regards to the continuous changing in causative microorganisms isolated from patients with uti and antibiotic sensitivity patterns, it is recommended that bacterial sensitivity patterns in populations are determined in any region annually. . objectives this study aimed to detect and also compare the frequency and drug resistance pattern of gram negative bacteria isolated from p...

background: in this study, the efficacy of nitazoxanide in the treatment of helicobacter pylori isolates, which were resistant to metronidazole, was examined.   methods: one hundred twenty two patients who underwent endoscopy examinations at kasra and laleh hospitals in tehran from november 2014 to july 2015 were enrolled. helicobacter pylori strains were isolated from the patients’ endoscopy b...

background and objectives: acinetobacter spp. are important causes of nosocomial infections. they possess various antibiotic resistance mechanisms including extended spectrum beta lactamases (esbls). the aim of this study was to determine antibiotic resistance profile of acinetobacter clinical isolates especially among esbl-producing strains and to investigate the antimicrobial effects of oleo-...

staphylococcus aureus is a hazard to human health since they can cause a wide variety of hospital-associated infections ranging from minor skin infections to post-operative wound infections and food poisoning which produces many different virulence factors, including enterotoxins (ses). although  studies  have  been  done  regarding  the difference  between  virulence  factors  of  sensitive st...

abstractpropionibacterium acnes is propounded as one of the significant factors in occurrence of acne. today, due to development of the antibiotic resistance, most of the acne treatments are faced with failure. in order to determine the antibiotic resistance of the p.acnes strains isolated from the patients with acne, this research has been carried out. 70 samples collected using microbial cult...

background: one of the main causes of sexually transmitted diseases is group b β- hemolytic streptococci (gbs) multiplying in the genital tracts. penicillin is the most common drug for the treatment of infections caused by these bacteria, but in patients suffering from penicillin allergy, erythromycin and clindamycin are used as alternative therapeutic drugs against gbs. recently, resistance to...
