They help keep your body healthy by regulating the number of bacteria, fungi, and viruses around you. They also help to fight diseases like pneumonia and sepsis. Answer and Explanation: Gram-positive bacteria are the ones that stain purple when they are stained with Gram's me...
In the last six challenges correct answers for Gram stain were 77% -99% while morphology 73% -96%. Conclusions: We observed statistically significant improvement when reading Gram stains by providing frequent challenges to medical laboratory scientists. The clinical importance of Gram stain results ...
Bacteria are identified as H. mustelae on the basis of gram-stain morphology; production of urease, catalase, and oxidase; resistance to cephalothin; and sensitivity to nalidixic acid. Necropsy and Histopathologic Findings The histopathological changes occurring in the stomach closely coincided in ...
The sensitivity, specificity, and predictive values of each individual diagnostic arm of Gram stain were determined. Combinations were performed in series, which required both tests to be positive to confirm infection, and also in parallel, which necessitated both tests to be negative to rule out ...
Gram-positive bacteria have a thick peptidoglycan cell wall, about 20 to 80 nm (nanometers or one-billionths of a meter) thick. Examples includestaphylococci, streptococci, lactobacilliandBacillusspecies. These bacteria stainpurple or red, but usually purple, with Gram stain, as the peptidoglycan ...

Vaginal cultures for BV diagnosis generally lack positive predictive value or diagnostic value as the infection itself usually is polymicrobial in nature [111,169,170]. Also, bearing in mind that performing conventional bacteria culture can be challenging to observe fastidious microbes and is time-...
