Zoonotic Diseases Flashcards
diseases transmitted among humans and other vertebrae
zoonosis
disease humans can give animals
reverse zoonosis
diseases that people incorrectly think they can give animals
pseudo zoonosis
modes of transmission
direct, indirect (fomites, biological factors, mechanical factors)
people most likely infected with zoonotic diseases
non-traditional pets, people who work in wildlife settings, ecotourism, vet practice
prevention of zoonotic diseases
vax, flea and tick control, sanitation and hygiene, water treatment, counseling clients
bacteria of Botulism
Clostridium botulinum
hosts for Botulism
mammals, fish, birds
transmission of Botulism
bacterial spore, wound
where is Botulism bacteria found
soil worldwide, decaying vegetation and carcasses
how humans contract Botulism
improperly cooked food
incubation of Botulism
2 hours to 2 weeks
clinical signs of Botulism
GI signs, difficult chewing swallowing, drooling, visual impairment, weakness, ataxia
treatment of Botulism
supportive, wound cleaning
prevention of Botulism
avoid contaminated food, rodent control, vaccine for horses, cattle, goats
bacteria for cat scratch disease
Bartonella henselae
transmission of cat scratch
bite, scratch, lick
clinical signs of cat scratch
pustule, lymphadenopathy, headache, lethargy, fever
treatment of cat scratch
cats: rarely show signs, 3 wk course of antibiotics
humans: antibiotics, anti-inflammatory, pain meds, self limiting
prevention of cat scratch
keep cats indoors, avoid rough housing, clean bite or scratch, trim claws, control fleas
bacteria for Pasteurellosis
Pasteurella multocida
hosts of Pasteurellosis
normal flora in resp and dig tracts of dogs and cats (animal bites)
transmission of Pasteurellosis
saliva and broken skin
clinical signs of Pasteurellosis in animals
only causes illness when stressed, normal resp inhabitant, cats and dogs develop wound infections
clinical signs of Pasteurellosis in humans
inflammation around bite wound, severity depends on location
prevention of Pasteurellosis
no vax, proper animal restraint, cleaning bite wound
bacteria of the plague (black death)
Yersinia pestis
plague bacteria is destroyed by…
sunlight
host of the plague
rats, prairie dogs, squirrels, burrowing rodents
T/F plague is reportable
duh, true.
transmission of the plague
flea bite: bubonic plague
airborne: pneumonic plague
who is most affected by the plague
cats, cats transfer it to humans
symptoms of the plague in cats
fever, lymphadenopathy, abscess formation, encephalitis, hemorrhagic pneumonia
symptoms of the plague in dogs
fever, lymphadenopathy, self-limiting
diagnosis of the plague
Hx, clin signs, culture, seological testing
treatment for the plague
antibiotics, isolation
what is known as “circling disease”
listeriosis
bacteria of listeriosis
Listeria monocytogens
how tough is listeriosis
extremely resistant
when is listeriosis most common
winter-spring
what causes listeriosis
less acidic pH of soiled silage
how fast do outbreaks occur after feeding of spoiled silage
<10 days
T/F listeriosis is reportable
true
transmission of listeriosis
animal to animal by fecal-oral
clinical signs of listeriosis
ENCEPHALITIS, infection, neurologic changes, unilateral/ipsilateral weakness, circling
who is most susceptible for listeriosis
immunocompromised, pregnant woman
treatment for listeriosis
penicillin, ceftiofur, erythromycin, avoid soiled silage
creeping eruption, ground itch, sandworms
cutaneous larval migrans
etiology of cutaneous larval migrans
hookworms (Ancylostomatidae)
T/F cutaneous larval migrans are reportable
false
where do cutaneous larval migrans live
intestines of dogs, cats, and wild animals
transmission of cutaneous larval migrans
hookworms shed from feces of infected animal
clinical signs of cutaneous larval migrans
redness, intense pruritus
treatment of cutaneous larval migrans
albendazole, anti-itch, dewormer
scientific name of roundworms
Toxocara canis and Toxocara cati
T/F roundworms are reportable
false
how do roundworms travel through the body
through intestinal wall into blood stream and causes inflammation and damage
what do roundworms harm
liver. heart, CNS
transmission of roundworms
fecal-oral
clinical signs of roundworms
depends on location, can cause tissue damage, can cause fever coughing, inflammation of liver or eye
treatment of roundworms
antiparasitic, cannot fix damage to eye
intestinal infection from contaminated water or poor sanitation
Giardiasis (Giardia)
symptoms of Giardia
abdominal cramps, bloating, nausea
transmission of Giardia
soil, food, water contaminated with feces
clinical signs of Giardia
diarrhea, flatulence, greasy stool, cramps, nausea, dehydration
prevention of Giardia
avoid contaminated water, good hygiene
