AIM The aim of this study was to investigate anaerobic and aerobic bacteria profile and determination of antibiotic susceptibility pattern in aerobic bacteria. METHOD Specimens were cultured using optimal aerobic and anaerobic microbiological techniques. Identification of bacterial isolates was performed by standard microbiological methods and antibiotic(More)
BACKGROUND Surgical Site Infections (SSIs) are infections of incision or deep tissue at operation sites. These infections prolong hospitalization, delay wound healing, and increase the overall cost and morbidity. OBJECTIVES This study aimed to investigate anaerobic and aerobic bacteria prevalence in surgical site infections and determinate antibiotic(More)
Introduction: Multi-drug resistant (MDR) P. aeruginosa is constantly increasing and causing severe issues in combatting widely spread health problems. The aim of this study was to assess colistin susceptibility in MDR P. aeruginosa isolates obtained from different infection sites. Methods: Ninety clinical isolates of P. aeruginosa were collected from(More)
BACKGROUND Diarrhea is the most frequent health problem among children in developing countries. Defining the etiology of acute diarrhea is critical to disease therapy and prevention. Some anaerobic bacteria such as Enterotoxigenic Bacteroides fragilis (ETBF) strains cause diarrheal disease by production of enterotoxin in children less than 5 years old. (More)
Accurate identification of early onset neonatal sepsis (EOS) is challenging. Blood culture has been considered as a gold standard method but the identification of EOS is intricate by a high false-negative results. This review provides an overview of biomarkers as indicators for the diagnosis of EOS. There is an affluence of studies appraising diagnostic(More)
Background:Bacteroides fragilis is the most common anaerobic pathogen isolated from surgical site infections (SSIs). Metronidazole resistance is increasing and the mechanisms of resistance are not clear in some isolates. The aim of the present study was to investigate the metronidazole susceptibility prevalence, and detect nim genes in B. fragilis isolates(More)
Nowadays, all people are at risk of infectious diseases that are mainly caused by bacteria causing infection. There is a permanent demand for an appropriate detection method that is affordable, practical, careful, rapid, sensitive, efficient and economical. Aptamers are single stranded DNA or RNA oligonucleotides, which can be recognized specifically and(More)
Autoimmune disease are defined as the attacks on host tissue by the immune system. Several factors, e.g. genetic and environmental triggers (in particular, viruses, bacteria, and other infectious pathogens) play a role in the development of autoimmune diseases. Bacterial infections are related to several autoimmune diseases, e.g. chronic inflammations and(More)
bacteria is Pseudomonas aeruginosa (P. aeruginosa), which is usually associated with human nosocomial infections,sever opportunist infections, ventilated-associated pneumonia (VAP) andinfections in the lungs of patients suffering from cystic fibrosis (1, 5-7).P. aeruginosa is a one of main respiratory tract pathogen. Rapid colonization of biofilm-forming(More)
Infectious diseases are among the common leading causes of morbidity and mortality worldwide. Associated with the emergence of new infectious diseases, the increasing number of antimicrobial resistant isolates presents a seriousthreat to public health and hospitalized patients. A microbial pathogen may elicit several host responses and use a variety of(More)
