In vitro studies were carried out with 4175 Gram-positive clinical isolates, comparing telithromycin broth microdilution MICs with disc diffusion zone diameters. Provisional interpretive criteria for testing staphylococci were > or =23 mm for susceptible and < or =19 mm for resistant. Because pneumococci and other streptococci require increased CO(2), the corresponding zone sizes are 3 mm small...
Results In Januaryof 2010, 21 neonatal infection cases with 2 death reported were screened by clinical signs. 76.2% of them had cesarean delivery and 23.8% were given normal birth. Clinical presentations were fever 100%, cyanosis 76%, breath distress 65%, abdominal filling 59%, abdominal vein unroll 53%, hyperbilirubinemia 53%, irritability 47% and rigidity 12%. Clinical samplings gathered from...
A study was carried out to determine the pattern of microbiological organisms causing community acquired pneumonia in adult patients admitted to Penang Hospital between November 1999 and August 2000. Altogether, 98 patients (64 males, 34 females) with a mean age (+/- S.D.) of 55.9 (+/- 19.0) (range 15 to 87) years were included in the study. Causative organisms were identified in 42 patients (4...
Broad-range rDNA polymerase chain reaction (PCR) provides an alternative, cultivation-independent approach for identifying pathogens. In 1995, the Centers for Disease Control and Prevention initiated population-based surveillance for unexplained life-threatening infections (Unexplained Death and Critical Illness Project [UNEX]). To address the causes of UNEX cases, we examined 59 specimens from...
Group A Streptococcus (GAS, Streptococcus pyogenes) causes invasive infections including streptococcal toxic shock syndrome (STSS) and local infections. To our knowledge, this is the first report of a case of an invasive GAS infection with pneumonia and pleural empyema (PE) followed by STSS (disseminated intravascular coagulation [DIC] and acute renal insufficiency) in a healthy male adult. He ...
Streptococcus pneumoniae is the most frequent cause of pneumonia and meningitis. Because S pneumoniae can colonize the upper respiratory tract and antibiotic treatment may inhibit growth, culture-based diagnosis can be problematic. An immunohistochemical assay using a polyclonal antibody against pneumococci was used to test formalin-fixed, paraffin-embedded tissue samples from 46 patients for w...
Commensal organisms are frequent causes of pneumonia. However, the detection of these organisms in the airway does not mean that they are the causative pathogens; they may exist merely as colonizers. In up to 50% cases of pneumonia, the causative pathogens remain unidentified, thereby hampering targeting therapies. In speculating on the role of a commensal organism in pneumonia, we devised the ...
BACKGROUND Under the existing national surveillance system in China for selected infectious diseases, bacterial cultures are performed for only a small percentage of reported cases. We set up a laboratory-based syndromic surveillance system to elucidate bacterial etiologic spectrum and detect infection by rare etiologies (or serogroups) for five core syndromes in the given study area. METHODS...
BACKGROUND Acute asthma exacerbations and pneumonia are important causes of morbidity and mortality in children and may coexist in the same children, although symptom overlap may lead to difficulties in diagnosis. Microbial and viral diversity and differential abundance of either may play an important role in infection susceptibility and the development of acute and chronic respiratory diseases...
in the present study, we have reported the total phenolic content, total flavonoid content, antioxidant and antimicrobial activity of aerial parts of salvia leriifolia extracts and fractions. methanolic, n-hexane, chloroform, and ethyl acetate extracts were screened to analysis their antioxidant activities by four complementary test systems, namely dpph free radical scavenging activity (rsa), t...
