Аntibiotic and serum resistance of Enterobacteriaceae strains isolated from outpatients with infections of urogenital tract (original) (raw)

2018, Journal of BioScience and Biotechnology

The present study is focused on the antibiotic and serum resistance of Enterobacteriaceae strains associated with community infections of the urogenital tract. During a one-year period from April 2016 to March 2017 total of 318 Enterobacteriaceae strains were collected from urine samples, vaginal and urethral secrets and ejaculates of outpatients with urinary and genital tract infections at IMDL "Chronolab" - Plovdiv, Bulgaria. The most common etiological agent was Escherichia coli (64.8%), followed by Klebsiella spp. (17%) and Proteus mirabilis (10.37%). The antibiotic susceptibility tests showed high resistance against ampicillin (49%), mecillinam (71%), doxycycline (41%) and high susceptibility to cephalosporins (cefuroxime 84.6%; cefoxitin 83.7%; cefotaxime 91.5%; cefepime 87.7%) and fluoroquinolones (ciprofloxacin 85%, norfloxacin 79%, levofloxacin 83%;). Significant resistance was established to nitrofurantoin (24%). Amongst the tested strains, 8.5% produced extended...
