Bacteria, yeast, and fungi

Question 1

Actinomyces

Answer 1

l gram-positive. Actinomyces species are facultatively anaerobic

fungus-like branched networks of hyphae

ubiquitous, occurring in soil and in the microbiota of animals

Question 2

Antibiotic used to indicate methicillin resistance

Answer 2

Oxacillin, implies resistance to all penicillins, cephalosporin, imipenem, and beta-lactam/beta-lactamase inhibitors and combinations such as amoxicillin/clavulanic acid. More stable and widely available than methicillin.

Question 3

Aspergillus

Answer 3

branching fungal hyphea

Question 4

Bartonella clarridgeiae

Answer 4

Gram-negative bacteria from the genus of Bartonella which was first isolated in the United States. Bartonella clarridgeiae is an zoonotic pathogen which can cause cat scratch disease

Question 5

Bartonella henselae

Answer 5

most common cause of Bartonellosis in cats in the US

Question 6

Bartonella quintana

Question 8

Bartonella weissii

Answer 8

bovine

Question 9

Blastomyces

Answer 9

broad-based budding yeast

Question 10

Borrelia burgdorferi

Answer 10

Causative agent of Lyme disease

Question 11

Campylobacteriosis

Answer 11

gram stain and visualize “gull shaped” gram negative rods

dog presentation: mucous-laden diarrhea

Question 12

Clostridium difficile

Answer 12

large, gram-positive, anaerobic, spore-forming motile rod and is the major cause of antibiotic-associated colitis in people. C difficile–associated diarrhea and disease develops spontaneously in a variety of other species including horses, pigs, calves, dogs, cats, hamsters, guinea pigs, rats, and rabbits

Question 13

Coccidioides immitis

Answer 13

spherule, 20-200 micrometer round, double-walled structure containing endospores.

Question 14

Cryptococcus

Answer 14

small yeast with large capsule, narrow based budding yeast

Treat with Fluconazole

Question 15

Cryptosporidium

Answer 15

primarily in neonatal calves but also in lambs, kids, foals, and piglets. Cryptosporidia cause varying degrees of naturally occurring diarrhea in neonatal farm animals.

Question 16

Dermatophilus congolensis

Answer 16

Long chain of branching cocci

Question 17

Dichelobacter nodosus

Contagious footrot in sheep

Question 18

Histoplasma

Answer 18

small intracellular yeast

Question 19

Most commonly reported cultures form endocarditis

Answer 19

Stphylococcus aureus, Stretococcus sp., Corynebacterium sp., Pseudomonas aeruginosa, Erysipelothric, E. coli, and Bartolenna sp.

Question 20

Nocardia

Answer 20

weakly staining Gram-positive, catalase-positive, rod-shaped bacteria. It forms partially acid-fast beaded branching filaments (acting as fungi, but being truly bacteria)

opportunistic, noncontagious, pyogranulomatous to suppurative disease of domestic animals, wildlife, and people.

Mastitis, pneumonia, abscesses, and cutaneous/subcutaneous lesions are the major clinical manifestations of nocardiosis in livestock and companion animals.

Question 21

Physiologic effects of endotoxemia

Answer 21

due to bacterial lipopolysaccharide

Question 22

Pseudomonas

Answer 22

Equine keratitis

Question 23

Pseudomonas

Answer 23

most common cause of bacterial keratitis, gram-negative bacteria. Treat with topic Tobramycin

Question 24

Rickettsia rickettsii

Answer 24

Causative agent fo Rocky Mountain Spotted Fever

Question 25

Salmonellosis

Answer 25

rod-shaped gram-negative bacterium belonging to the family Enterobacteriaceae, is the causative agent of salmonellosis. Salmonellosis in warm-blooded vertebrates is in most cases associated with serovars of Salmonella enterica. The most common type of infection is the carrier state, in which infected animals carry the pathogen for a variable period of time without showing any clinical signs. Clinical disease is characterized by two major syndromes: a systemic septicemia (also termed as typhoid) and an enteritis. Other less common clinical presentations include abortion, arthritis, respiratory disease, necrosis of extremities, and meningitis

Question 26

Sporotrichosis

Answer 26

Infectious, sporadic, chronic, granulomatous disease

Sporotrichosis has been reported in dogs, cats, horses, cows, camels, dolphins, goats, mules, birds, pigs, rats, armadillos, and people

Sporotrichosis may be grouped into three forms: lymphocutaneous, cutaneous, and disseminated. The lymphocutaneous form is the most common

Question 27

Toxoplasma

Answer 27

treat with Clindamycin
