dental abscess is a frequently occurring infectious process known to the health practice. the fate of the infection depends on the virulence of the bacteria, host resistance factors, and regional anatomy. serious consequences arising from the spread of a dental abscess lead to significant morbidity and mortality. acute dental abscess is polymicrobial, comprising of strict anaerobes, such as ana...
In the early days of HIV treatment, drug resistance occurred rapidly and predictably in all patients, but under modern treatments, resistance arises slowly, if at all. The probability of resistance should be controlled by the rate of generation of resistance mutations. If many adaptive mutations arise simultaneously, then adaptation proceeds by soft selective sweeps in which multiple adaptive m...
Abstract Background and Objective: Acinetobacter species are opportunistic important pathogens responsible for many nosocomial infections. The purpose of this study was to determine the drug resistan pattern Acinetobacter baumannii and prevalence of ESBL producing strains in Intensive Care Unit patients in Isfahan city hospitals. Material and Methods: The study was conducted on 100 Ac...
Background: Infections are one of the most important causes of death in infants, especially in developing countries. Inappropriate use and administration of antibiotics can contribute to the resistance and spread of infection. In this study, we determined the antibiotic resistance pattern of the bacteria isolated from clinical samples of blood, cerebrospinal fluid, and urine in the neonatal int...
BACKGROUND Resistance to triazoles was recently reported in Aspergillus fumigatus isolates cultured from patients with invasive aspergillosis. The prevalence of azole resistance in A. fumigatus is unknown. We investigated the prevalence and spread of azole resistance using our culture collection that contained A. fumigatus isolates collected between 1994 and 2007. METHODS AND FINDINGS We inve...
in the present study resistance of some elite lines of wheat at seedling stage were evaluated in cereal rusts greenhouse at seed and plant improvement institute in karaj and at adult plant stage in ahvaz under artificial inoculation with an isolate of leaf rust from ahvaz. for seedling resistance, different components of resistance were measured. the results showed that lines m-85-1, m-86-1 and...
many classes of antibacterial drugs are currently available for physicians to use, however the plan of antibiotic development has slowed during the last decade. the world health organization (who) has identified antimicrobial resistance as one of the 3 most important problems for human health. antimicrobial resistance is a growing problem worldwide, especially in hospitals, where resistant orga...
Background: Multidrug resistant Enterobacteriaceae which was confined to the hospital environments is now emerging in the domestic food related environments as well. The main objective of the present study was to investigate the prevalence of antibiotic resistant Enterobacteriaceae in the domestic food related environments. Methods: Resistance to ampicillin, chloramphenicol, ...
Background & Objective: Resistance patterns among nosocomial bacterial pathogens in hospitals may vary widely from country to country at any given point and within the same country over time. Acinetobacter baumannii is one of the most important bacteria that cause hospital-acquired infections. Therefore, surveillance of the antibiotic resistance of Acinetobacter baumannii is necessary, especial...
methicillin-resistant staphylococcus aureus (mrsa) is the main cause of hospital infection emerged over the last decades. rapid detection of mrsa is important for patient care and proper usage of infection control. detection of meca genes (encoding resistance to methicillin and other similar antibiotics) and nuc genes (encoding staphylococcal thermostable nuclease) by pcr method is now consider...
