Acinetobacter baumannii is an increasingly common multidrug-resistant pathogen in health care settings. Although the genetic basis of antibiotic resistance mechanisms has been extensively studied, much less is known about how genetic variation contributes to other aspects of successful infections. Genetic changes that occur during host infection and treatment have the potential to remodel gene ...

background and objective:  early diagnosis of streptococcus agalactiae remains difficult, since symptoms are very nonspecific. its frequency has not been completely investigated in urinary tract pathogen of pregnant ant and non pregnant women in iran. the aim of this study was determining the frequency of group b streptococci in female patients. materials and methods: a total of 11800 urine sp...

The relationships between schistosomiasis and its intermediate host, mollusks of the genus Biomphalaria, have been a concern for decades. It is known that the vector mollusk shows different susceptibility against parasite infection, whose occurrence depends on the interaction between the forms of trematode larvae and the host defense cells. These cells are called amebocytes or hemocytes and are...

BACKGROUND Healthcare-associated antibiotic-resistant (AR) infections increase patient morbidity and mortality and might be impossible to successfully treat with any antibiotic. CDC assessed healthcare-associated infections (HAI), including Clostridium difficile infections (CDI), and the role of six AR bacteria of highest concern nationwide in several types of healthcare facilities. METHODS D...

Introduction: Typhoidal Salmonella causes an invasive infection resulting in 200 000 deaths among 20 million patients annually. Typhoid remains a public health problem in Southeast Asia, the Indian subcontinent, Africa, and South America. Traveler’s diarrhea caused by Salmonella is common in Asia. Outbreaks of typhoidal Salmonella resistant to ampicillin, chloramphenicol, and t...

The laboratory diagnosis of varicella-zoster virus (VZV) infection was reevaluated by direct immunofluorescent-antibody staining (DFA) and centrifugation culture with newly available murine monoclonal antibodies. Specimen smears were examined by DFA using monoclonal antibodies to VZV and to herpes simplex virus types 1 and 2. Specimens were also inoculated into shell vials for centrifugation cu...

conclusions these findings showed no significant difference regarding the presence of icaadbc genes between blood and wound isolates. background the polysaccharide intercellular adhesion (pia) produced by staphylococcus aureus is effective in the protection of isolates from outer harsh conditions and progress of infection. objectives the aim of this study was to compare the icaabcd genes encodi...

OBJECTIVES We describe the emergence and dissemination of multidrug-resistant (MDR) Salmonella Typhimurium in humans, retail meat and food animals from Yucatan, Mexico. METHODS Salmonella Typhimurium isolates were collected through an active surveillance system and tested for susceptibility to 12 antimicrobial agents. Isolates that were non-susceptible to ceftriaxone were tested with 10 addit...
