Forty-seven infants and children with a variety of infections including bacteremia, ethmoiditis, and periorbital cellulitis, soft tissue infection, pneumonia, and lymphadenitis were treated with intravenous cefamandole. The infections were due to Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, and Haemophilus influenzae. The clinical response was prompt, and, with the e...

BAY 12-8039 is a new 8-methoxyquinolone with antibacterial activity against gram-positive bacteria which is significantly better than those of sparfloxacin or ciprofloxacin. The minimal inhibitory concentrations (MICs) for 90% of methicillin-susceptible Staphylococcus aureus and Staphylococcus epidermidis were 0.062 and 2 mg/l, respectively. The MIC90s for ciprofloxacin-resistant, methicillin-s...

Lower respiratory tract infections represent a major concern, especially with increasing numbers of resistant Streptococcus pneumoniae, extended-spectrum plactamase-producing Enterobacteriaceae, and Staphylococcus aureus with reduced susceptibility to vancomycin. Here, we report on the susceptibilities of isolates cultured from patients with lower respiratory tract infection to different antibi...

A survey of 303 urban and 156 rural children showed nasopharyngeal carriage of relatively resistant Streptococcus pneumoniae organisms in 14.2% and 19.2% of children, respectively. These organisms have minimum inhibitory concentrations for penicillin in the range of 0.12-1 microgram/ml. An analysis of 40 relatively resistant S. pneumoniae strains showed resistance to co-trimoxazole in 47.5%, tr...

OBJECTIVE To study the changes in the epidemiology of bacterial meningitis in the era of the Hemophilus influenzae (H. influenzae) type b vaccine and pneumoccous resistance. METHODS Retrospective study which included patients admitted to Hamad Medical Corporation, Doha, Qatar between January 1998 through to December 2000 with positive cerebrospinal fluid culture. RESULTS Thirty-seven patien...

Wide geographic variation in the prevalence of drug-resistant Streptococcus pneumoniae demonstrates the importance of tracking antimicrobial resistance locally. This survey of hospital microbiology laboratories in New York City found that penicillin resistance (MIC > or = 2.0 micrograms/ml) increased from 1.5% of S. pneumoniae isolates in 1993 to 6.3% in 1995 and that in 1995, one-third of isol...

background: selective antibody deficiency with normal immunoglobulins (sadni) may be identified as part of distinct primary or secondary immunodeficiency disorders. the clinical manifestations include recurrent, often severe or prolonged, upper or lower respiratory tract infections. objectives: to evaluate sadni in patients with recurrent sinopulmonary infections and its relation to igg subclas...

Background: Streptococcus pneumoniae and Haemophilus influenzae type b (Hib) is a leading cause of bacterial pneumonia, meningitis, and sepsis in children under 5-year of age. This study aims to estimate potentially preventable number of cases and deaths caused by Hib and pneumococcal in Iran.Materials and Methods:We used the burden of diseases model estimates of the World Health Organization (...

This report presents the case of a patient associated with a Streptococcus pneumoniae isolate that was resistant to a new ketolide antibiotic, telithromycin (minimum inhibitory concentration: 4 microg/ml). The patient, a 61-year-old female with bronchiectasis, was treated with 200-400 mg of clarithromycin daily for 6 years until the isolation of the resistant strain but without prior exposure t...

background:pneumonia and respiratory tract infections, is associated with high mortality and complications in humans. current antibiotics are used to treat this infectious disease, but may lead to many problems such as unwanted side effects and resistance to antibiotics. this study investigated the antibacterial activity of the hydro alcoholic extracts of the native medicinal plants peganum har...
