Zoonotics Flashcards
Organism for cutaneous anthrax
Bacillus Anthracis
starts as painless papule surrounded by vesicles then later become painless and necrotic
In severe cases can develop bacteremia –> death
**Organism of plague
Yersinia Pestis
Transmitted through rat flea (Xenopsylla cheopis)
Reservoirs: Rodents, dogs, squirrels, voles, chipmunk
**Organism of Leptospirosis
Leptospira interrogans
Leptospira can penetrate through intact mucous membrane or small cuts/ abrasions on skin:
Contaminated water (streams, rivers, standing water, moist soil)
Water is contaminated with infected rodent urine
hemorrhagic lesions in skin
Silver-staining [Warthin-starry]
Microscopic agglutination test (MAT)
Treatment: Penincillin / Doxycycline
**Organism of Cat scratch disease
Bartonella henselae
Gram negative coccobacilli
Transmitted through cat scratch/ bite
Transmitted through bite of cat flea
Causes axillary lymphadenopathy
Post-infection complication: subacute bacterial endocarditis in immunodeficient patients
**Organism of Tularemia
Francisella Tularenis
Rabbit fever; camping
Gram negative Coccobacilli
Transmitted by rabbit/ deer/ Tick bite/ insect bite/ inhaling infected animal tissue
Bite –> ulceroglandular painful papule
Localized axillary lymphadenopathy
Organism of Brucellosis
Brucella species
Very contagious, therefore it can only be grown in a bio safety cabinet
Unpasteurized dairy
Really high temperature-pyrexia (of unknown origin)
Intolerable pain (arthritis)
Weight loss
Endocarditis
Gram negative coccobacilli
**Organism of Pasteurellosis
Pasteurella multocida
Normal flora of an animal (dog/cat) bite
Endotoxin infect wound
*DO NOT SUTURE, it will only make the infection worse
Cellulitis, Osteomyelitis
Organism of HPS
Hanta virus
Reservoir is rodents
Shortness of breathe, fever, lung issues (lung infiltrates/ pleural effusions
Enveloped; BUNYA virus
