Full-text available
Background: Mycoplasma hominis (M. hominis) is an important cause of bacterial infections of the genital tract. Macrolides are the first selective agents used to treat mycoplasma infections. However, widespread use of macrolides has led to a rapid and global emergence of macrolide-resistant strains. We evaluated macrolide resistance in M. hominis...

Mycoplasma is a bacterium that lacks a cell wall around its cell membrane, that makes it naturally resistant to antibiotics such as beta-lactams, which target cell wall synthesis. These bacteria can be parasitic or saprotrophic. Several species of these bacteria are pathogenic in humans, including M. pneumoniae and M. genitalium. Mycoplasma pneumon...

Background & objective: Escherichia coli (E. coli) is a leading cause of urinary tract infections becoming resistant against beta-lactams and cephalosporins through different mechanisms, including ESBL production due to the presence of ESBL specific genes, including blaCTX-M and blaTEM. The purpose of the present study was to detect the uropathoge...
Article
Full-text available
Background There has been an increasing resistance rate to tetracyclines, the first line treatment for cholera disease caused by V. cholera strains, worldwide. The aim of the present study was to determine the global status of resistance to this class of antibiotic among V. cholera isolates. Methods For the study, electronic databases were searche...
Article
Staphylococcus aureus is a common pathogen causing hospital infections. The increasing rate of healthcare-associated infections caused by methicillin-resistant Staphylococcus aureus (MRSA) in developing countries has led to many public health problems. This study aimed to investigate the molecular epidemiology as well as the antibiotic resistance p...
Article
Background: Resistance to tetracyclines, the first-line treatment for urogenital infections caused by Mycoplasma hominis and Ureaplasma species, is increasing worldwide. The aim of the present study was to determine the global status of resistance to this class of antibiotics. Methods: Electronic databases were searched using keywords including...

The coronavirus disease 2019 (COVID-19) is an emerged infectious disease characterized by a severe pneumonia leading to death in some cases. Currently, no licensed vaccines, drugs, or biologics have been confirmed to be absolutely effective in prophylaxis or treatment of this novel infection. Therefore, the treatment of this highly contagious disea...
Article
The objective of this study was to compare the release of endotoxin and pro-inflammatory cytokines as well as pregnancy outcomes after antibiotic exposure in healthy and bacterial infected pregnant rats. Thirty female Wistar pregnant rats were divided into five groups. Group A considered as control and received intraperitoneal saline 0.9% on 17th g...

Resistance to antimicrobial compounds in E. coli strains is increasing. Integrons are mobile genetic elements that lead to the spread and transfer of antibiotic resistance genes in bacteria. The aim of the present study was to determine the frequency of class 1 and 2 integrons as well as the antimicrobial resistance in E.coli strains isolated from...
Article
The role of asymptomatic infections caused by Chlamydia trachomatis in male infertility and the efficacy of antibiotics in the treatment of this condition are not yet definitely determined. A total of 165 infertile males having abnormal semen parameters (study group) as well as 165 healthy fertile men (control group) were included. Semen samples we...
Article
Full-text available
Objectives: To elucidate the association between asymptomatic infections caused by Mycoplasma genitalium and male infertility, and evaluate the role of antibiotic therapy in treatment of this failure. Methods: A total of 165 infertile males having abnormal semen parameters (study group) and 165 healthy fertile men (control group) were included....
Article
The role of asymptomatic infections caused by Ureaplasma species in male infertility and the efficacy of antibiotics in treatment of this failure is not yet definitely determined. A total of 165 infertile males having abnormal semen parameters (study group) as well as 165 healthy fertile men (control group) were included in this study. Semen sample...

Article
Full-text available
Background: Urogenital mycoplasmas are potentially pathogenic species causing genitourinary tract infections that may be initially asymptomatic but can progress and lead to severe complications and threaten reproductive health. However, the overall prevalence rate of this bacterium and its probable impacts on fertility potential have yet to be det...
Article
Background Chlamydia trachomatis is one of the sexually transmitted pathogens causing reproductive health-threatening diseases worldwide. However, its role in infertility, particularly in asymptomatic individuals, is not yet definitely determined. Methods For the study, electronic databases were searched using the following keywords; ‘Chlamydia tra...

Full-text available
Objective: To determine the overall prevalence of Chlamydia trachomatis in Iranian males and females and to find out the effect of this bacterium on fertility potential and its association with urogenital symptoms. Methods: We searched both English and Persian electronic databases using keywords 'Chlamydia', 'Chlamydia trachomatis', 'prevalence'...
Article
Full-text available
Objective: Infection with genital Mycoplasmas may have harm effects on the reproductive health of men, thus leading to male infertility. This study was performed to detect the prevalence of these bacteria and to study the sperm parameters in infertile men who referred to Royan Institute during 2009. Materials and Methods: Semen samples were collect...
