Staphylococcal infections have high occurrence in Jordanian patients. This study was carried out to determine the rates of high- and low-level mupirocin resistance (MupH and MupL) among staphylococci with the molecular characterization. Two hundred and thirty-two non-duplicate Staphylococcus spp. isolated from different clinical specimens were tested for mupirocin susceptibility using disk diff...

INTRODUCTION Chronic dacryocystitis results in chronic infection and inflammation of the lacrimal sac. OBJECTIVE To identify the aetiology of chronic dacryocystitis and to determine their antimicrobial susceptibility pattern. MATERIALS AND METHODS A cross - sectional study was undertaken including 120 lacrimal swab materials collected from patients aged above 15 years suffering from chronic...

BACKGROUND Colonization of humans with Staphylococcus aureus is a critical prerequisite of subsequent clinical infection of the skin, blood, lung, heart and other deep tissues. S. aureus persistently or intermittently colonizes the nares of approximately 50% of healthy adults, whereas approximately 50% of the general population is rarely or never colonized by this pathogen. Because microbial co...

Continuous ambulatory peritoneal dialysis is an important modality of therapy for patients with renal disease. However, peritonitis continues to be a major risk factor and is usually treated by intraperitoneal administration of antimicrobial agents. Few data are available concerning the stability of antimicrobial agents in peritoneal dialysis solution beyond 48 h. Our investigation was designed...

Among hospital-associated infections, healthcare-associated central nervous system infections are quite important because of high morbidity and mortality rates. The causative agents of healthcare-associated meningitis differ according to the status of immune systems and underlying diseases. The most frequent agents are Gram-negative bacilli (Pseudomonas spp., Acinetobacter spp., Escherichia col...

OBJECTIVE To study the activity of several antibiotics against Staphylococcus spp. MATERIAL AND METHODS The study included 1209 strains of Staphylococcus spp. from two institutions; Instituto Nacional de Pediatría (National Institute of Pediatrics) and Hospital Infantil de México Federico Gómez (Mexico City Children's Hospital). Minimum Inhibitory Concentrations of all antibiotics were determ...

By use of the staphylolytic enzyme lysostaphin, a method was devised for isolating and purifying highly polymerized deoxyribonucleic acid (DNA) from lysostaphinsusceptible Micrococcaceae. Staphylococcus aureus DNA isolated by this procedure gave an estimated molecular weight of ca. 2 x 10(8) and a residual protein content of 2.3%. The mole percentage of guanine + cytosine (GC) present in the DN...

BACKGROUND The discharging ear is a common presentation in medical practice affecting all age groups but primarily children. This study shows the current aetiological causes of ear discharge and their antibiograms, data which would guide empirical treatment of ear infections, and also form a basis for further research. METHODOLOGY This was a retrospective review of laboratory records of all e...

The methanolic stem bark extract of Ficus thonningii (Moraceae) was subjected to preliminary phytochemical screening and in vitro antimicrobial tests. The phytochemical tests was carried out using standard methods of analysis and these investigations revealed the presence of alkaloids, anthraquinones, carbohydrates, flavonoids, saponins and tannins. The antimicrobial activity of the plant extra...

OBJECTIVE To evaluate, sequentially, tracheal aspirates from patients admitted to a pediatric intensive care unit and to associate these pathogens with length of hospital stay, previous use of antimicrobial therapy and diagnoses of ventilator-associated pneumonia. METHODS The study population consisted of patients admitted to a pediatric intensive care unit, between November 2002 and December...
