A genus that consists of filamentous anaerobes, many of which are commonly found in the gastrointestinal tract, vagina, and mouth.

• Bifidobacterium

• Corynebacterium

• Mycobacterium

• Actinomyces

A genus that is much studied representative of Actinobacteria. It play an important role in soil ecology, and some species are human pathogens.

• Bifidobacterium

• Corynebacterium

• Mycobacterium

• Actinomyces

A genus that contain diaminopimelic acid in their cell walls, and microscopically often form palisades, or pairs of rod-shaped cells resembling the letter V. Cells.

• Bifidobacterium

• Corynebacterium

• Mycobacterium

• Actinomyces

A genus that is represented by bacilli covered with a mycolic acid coat.

• Bifidobacterium

• Corynebacterium

• Mycobacterium

• Actinomyces

A genus that contains only one species, G. vaginalis. This species is defined as “gram-variable” because its small coccobacilli do not show consistent results when Gram stained.

• Gardnerella

• Corynebacterium

• Mycobacterium

• Actinomyces

What Clostridium spp. is the third most common cause of food poisoning in the United States and is the causative agent of an even more serious disease called gas gangrene.

• C. Perfringens

• C. Tetani

• C. botulinum

• C. Difficile

What Clostridium spp. is a common source of hospital-acquired infections, that can result in serious and even fatal cases of colitis?

• C. Perfringens

• C. Tetani

• C. botulinum

• C. Difficile

What Clostridium spp. Produces toxin that blocks the release of acetylcholine in neuromuscular junctions, causing flaccid paralysis.

• C. Perfringens

• C. Tetani

• C. botulinum

• C. Difficile

What Clostridium spp. that causes tetanus and cause a life-threatening spastic paralysis?

• C. Perfringens

• C. Tetani

• C. botulinum

• C. Difficile

What low G+C gram-positive bacteria that include both bacilli and cocci in the genera Lactobacillus, Leuconostoc, Enterococcus, and Streptococcus?
