Bacteria, yeast, and fungi Flashcards
Actinomyces
l gram-positive. Actinomyces species are facultatively anaerobic
fungus-like branched networks of hyphae
ubiquitous, occurring in soil and in the microbiota of animals
Antibiotic used to indicate methicillin resistance
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.
Aspergillus
branching fungal hyphea
Bartonella clarridgeiae
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
Bartonella henselae
most common cause of Bartonellosis in cats in the US
Bartonella quintana
Trench Fever in humans and is transmitted by the human louse
Bartonella vinsonii
has been associated with endocarditis in dogs
Bartonella weissii
bovine
Blastomyces
broad-based budding yeast
Borrelia burgdorferi
Causative agent of Lyme disease
Campylobacteriosis
gram stain and visualize “gull shaped” gram negative rods
dog presentation: mucous-laden diarrhea
Clostridium difficile
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
Coccidioides immitis
spherule, 20-200 micrometer round, double-walled structure containing endospores.
Cryptococcus
small yeast with large capsule, narrow based budding yeast
Treat with Fluconazole
Cryptosporidium
primarily in neonatal calves but also in lambs, kids, foals, and piglets. Cryptosporidia cause varying degrees of naturally occurring diarrhea in neonatal farm animals.
Dermatophilus congolensis
Long chain of branching cocci
Dichelobacter nodosus
Contagious footrot in sheep
Histoplasma
small intracellular yeast
Most commonly reported cultures form endocarditis
Stphylococcus aureus, Stretococcus sp., Corynebacterium sp., Pseudomonas aeruginosa, Erysipelothric, E. coli, and Bartolenna sp.
Nocardia
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.
Physiologic effects of endotoxemia
due to bacterial lipopolysaccharide
Pseudomonas
Equine keratitis
Pseudomonas
most common cause of bacterial keratitis, gram-negative bacteria. Treat with topic Tobramycin
Rickettsia rickettsii
Causative agent fo Rocky Mountain Spotted Fever
Salmonellosis
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
Sporotrichosis
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
Toxoplasma
treat with Clindamycin
