Dark-field microscopy can be used to determine infection with:   Fusobacterium nucleatum   Nocardia asteroides Treponema pallidum   Clostridium difficile

The tech is working in microbiology and typically there is an automatic call list generated by the laboratory information system (LIS) for urgent microbiology alerts. The LIS is currently down for maintenance so the tech has to manually pull a list of urgent reports. Which of the following shoud the tech consider as an urgent result? 

The colonies of Escherichia coli have a peculiar metallic sheen when grown on:   eosin methylene blue agar  Hektoen-enteric agar MacConkey agar   brilliant-green agar

In the presence of polymorphonuclear leukocytes and pyogenic organisms, the cerebrospinal fluid sugar and protein are usually:   Glucose Decreased/ Protein increased Glucose increased/ Protein decreased Glucose Normal/Protein increased  Glucose decreased/Protein normal

The organism believed to be a cause of human peptic ulcer disease as well as the most frequent cause of gastritis is _____.   Salmonella typhimuridum              Yersinia enterocolitica Campylobacter jejuni                   Helicobacter pylori

Purulent material is obtained from a carbuncle and submitted for bacterial culture. The direct smear reveals many gram-positive cocci and white blood cells. The culture shows growth in the primary broth and on the sheep blood agar plate and no growth on the MacConkey agar plate. The colonies on the blood agar plate are butyrous, white, and beta-hemolytic. Both glucose and mannitol are fermented. Although the slide coagulase test is negative, the tube coagulase test is positive. The most probable identity of this isolate is:   Micrococcus lysodeikticus Staphylococcus epidermidis Staphylococcus aureus   Staphylococcus saprophyticus

Sentinel Event cases cannot be duplicated (ex: two students cannot use the same sentinel event case).

On xylose-lysine-desoxycholate (XLD) agar, Salmonella typhi appears as :   Red colonies with black centers Yellow colonies with black centers Green colonies with black centers Blue colonies with red centers

Meningitis due to Haemophilus influenzae occurs most frequently in:   Adolescents  young women middle-age men  infants under 2 months

A TSI tube showing an alkaline slant and acid deep signifies that the organism:   ferments lactose only ferments sucrose only ferments glucose only ferments lactose, sucrose, and glucose
