the study was carried out to develop an efficient approach for prediction the genotoxicity of carbon nanotubes. the experimental data on the bacterial reverse mutation test (ta100) on multi-walled carbon nanotubes (mwcnts) was collected from the literature and examined as an endpoint. by means of the optimal descriptors calculated with the monte carlo method a mathematical model of the endpoint...

We evaluated the reliability of a passive bacterial agglutination test to detect Salmonella typhi somatic antigen(s) in the sera of patients with typhoid fever. It was positive in 32 of 33 bacteriologically proven typhoid fever cases. Among 13 patients with a presumptive diagnosis of typhoid fever, 11 were positive by passive bacterial agglutination. The serum of one patient with paratyphoid A ...

With a novel real-time multiplex polymerase chain reaction test, the LightCycler SeptiFast® test, 25 bacterial and fungal species can be identified directly in blood. The SeptiFast® test has been used for rapid etiologic diagnosis in infectious endocarditis using blood samples but has not been evaluated directly on cardiac vegetations in patients being treated for infectious endocarditis. We pr...

BACKGROUND Spontaneous bacterial peritonitis is defined as an ascetic fluid infection without an evident intra-abdominal surgically treatable source. Spontaneous bacterial peritonitis is one of the severe complications in patients with cirrhosis and ascites. Without early antibiotic treatment, this complication is associated with high mortality rate; therefore, early diagnosis and treatment of ...

background: streptococcus agalactiae, also known as group b streptococcus (gbs) is a commensal organism in the urogenital tract and rectum in approximately 25% of the healthy adult female population. the bacterium is the leading cause of bacterial meningitis, pneumonia, and sepsis in human infants. materials and methods: our study was performed over a three - month period from april to june 201...

the objective of the present study was to determine whether there was an association between the in vitroantimicrobial sensitivity test results of subclinical mastitis pathogensand bacteriological cure following intramammary treatment using a combination of nafcillin, penicillin, and streptomycin (nps). eighty-six intramammary pathogens from 43 cows were examined inthis study. most intramammary...

Tuberculous meningitis (TBM) is a severe infection of the central nervous system, particularly in developing countries. Prompt diagnosis and treatment are necessary to decrease the high rates of disability and death associated with TBM. The diagnosis is often time and labour intensive; thus, a simple, accurate and rapid diagnostic test is needed. The adenosine deaminase (ADA) activity test is a...

Objective. Bacterial meningitis is associated with significant morbidity and mortality if not diagnosed treated early. Isolation of the causative agent from cerebrospinal fluid culture gold standard for diagnosis this condition; however, it takes several days results to be available. The FilmArray™ Meningitis/Encephalitis (ME) panel a nucleic acid-based test that allows simultaneous detection 1...
