What causes lyme disease?

A laboratory is evaluating an enzyme-linked immmunosorbent assay (ELISA) for detecting an antibody to cyclic citrullinated peptide (CCP) which is a marker for rheumatoid arthritis. The laboratory includes serum from healthy volunteers and then serum from patients with other connective tissue disorders (not RA). These specimens are included to determine the ____________ of the ELISA.

What type of antigen is used in the RPR card test for syphilis?

A gram negative rod was isolated from a wound infection cause by a bite from a pet cat. The following characteristic reactions were seen:Oxidase = positiveGlucose OF = fermentativeCatalase = positiveMotility = negativeMacConkey agar = no growthWhich one of the following is the most likely?

Fluid from a black cutaneous lesion was submitted for routine bacteriological culture. After 18 hours of incubation in 3-5% CO2, there was no growth on MacConkey agar, but 3+ growth on sheep blood agar. The colonies were nonhemolytic, 4 to 5 mm in diameter and off-white with ground glass appearance. A gram stain smear of a typical colony showed large, gram-positive rectangular rods. This organism is most likely:

The most specific assays for human chorionic gonadotropic (hCG) use antibody reagents against which subunit of hCG?

An anaerobic gram-negative bacillus isolated from blood culture following bowel surgery grew smooth, white nonhemoltyic colones. A Gram stain showed pale, bipolar-staining rod with rounded ends. Bile stimulated growth of the organism and catalase was produced. The isolate was not inhibited by colistin, vancomycin; indole was not produced. The most likely identification of this organism is:
