Tubercle bacilli, which survived heat fixation, were detected with a slide culture technique which allowed the entire smear to be examined. Both conventional flame fixation and the use of a controlled hot-plate failed to render tuberculous sputum smears safe for further handling. Smears which were stained with the phenol-auramine method failed to yield growth on culture. If delay between prepa...

A differentiation method of human bone marrow mesenchymal stem cells (MSCs) to chondrocytes was developed for the construction of a three-dimensional (3D) cartilage tissue. The adhesive cells, which were isolated from a human bone marrow aspirate were embedded in type I collagen in a poly-L: -lactate-glycolic acid copolymer (PLGA) mesh and cultivated for 4 week together with growth factors. The...

Specimens collected from 182 patients with histories suggesting chlamydial disease were examined by conventional culture and direct immunofluorescence techniques. Chlamydia trachomatis was identified by both methods in 57% of all patients. There was no significant difference between the two methods in detecting C trachomatis. Where a tissue culture service is not already established, cost analy...

Specimens from 95 patients attending a venereal diseases clinic were examined for gonococci by three methods-a conventional culture technique using modified Thayer-Martin medium, microscopy of a Gram-stained direct smear, and the Microcult system. For 56?' of the specimens the results by all three methods agreed. Assuming the results obtained by culture on Thayer-Martin medium to be correct, th...

Here, we present a novel method for culturing kidneys in low volumes of medium that offers more organotypic development compared to conventional methods. Organ culture is a powerful technique for studying renal development. It recapitulates many aspects of early development very well, but the established techniques have some disadvantages: in particular, they require relatively large volumes (1...

Achieving a rapid microbiological diagnosis is crucial for decreasing morbidity and mortality of patients with a bloodstream infection, as it leads to the administration of an appropriate empiric antimicrobial therapy. Molecular methods may offer a rapid alternative to conventional microbiological diagnosis involving blood culture. In this study, the performance of a new technology that uses br...

background bacterial meningitis is still considered as one of the most dangerous infectious diseases, which causes numerous complications and high mortality if not diagnosed and treated timely. objectives this study was performed to determine antimicrobial resistance patterns of bacterial pathogens isolated from acute bacterial meningitis at tabriz children educational-health care center in ira...
