1
Q

Actinomyces

A

l gram-positive. Actinomyces species are facultatively anaerobic

fungus-like branched networks of hyphae

ubiquitous, occurring in soil and in the microbiota of animals

2
Q

Antibiotic used to indicate methicillin resistance

A

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.

3
Q

Aspergillus

A

branching fungal hyphea

4
Q

Bartonella clarridgeiae

A

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

5
Q

Bartonella henselae

A

most common cause of Bartonellosis in cats in the US

6
Q

Bartonella quintana

A

Trench Fever in humans and is transmitted by the human louse

7
Q

Bartonella vinsonii

A

has been associated with endocarditis in dogs

8
Q

Bartonella weissii

A

bovine

9
Q

Blastomyces

A

broad-based budding yeast

10
Q

Borrelia burgdorferi

A

Causative agent of Lyme disease

11
Q

Campylobacteriosis

A

gram stain and visualize “gull shaped” gram negative rods

dog presentation: mucous-laden diarrhea

12
Q

Clostridium difficile

A

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

13
Q

Coccidioides immitis

A

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

14
Q

Cryptococcus

A

small yeast with large capsule, narrow based budding yeast

Treat with Fluconazole

15
Q

Cryptosporidium

A

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

16
Q

Dermatophilus congolensis

A

Long chain of branching cocci

17
Q

Dichelobacter nodosus

A

Contagious footrot in sheep

18
Q

Histoplasma

A

small intracellular yeast

19
Q

Most commonly reported cultures form endocarditis

A

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

20
Q

Nocardia

A

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.

21
Q

Physiologic effects of endotoxemia

A

due to bacterial lipopolysaccharide

22
Q

Pseudomonas

A

Equine keratitis

23
Q

Pseudomonas

A

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

24
Q

Rickettsia rickettsii

A

Causative agent fo Rocky Mountain Spotted Fever

25
Q

Salmonellosis

A

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

26
Q

Sporotrichosis

A

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

27
Q

Toxoplasma

A

treat with Clindamycin
