Inf Dz's of the Dog pt 2 Flashcards
(28 cards)
Clinical signs of C botulinum
- weakness and flacid paralysis
- progressive, symmetrical ascending paralysis
- mydriasis, decreased gag reflex, excess salication, diminished palpebral reflexes and weak vocalization
- HR variable, constipation/urinary retention might happen
Dx of C botulinum
CS
EMG
Finding the toxin in serum, feces, vomitus, or stomach content
Tx for C botulinum
supportive care
anti toxin is Crap bc it’s doesn’t contain specific type C (for crap) antitoxin
Antibacterials- metro or penicillin
prev- heat food + vx
2 toxins found in C tetani
tetanoleptin- hemolysis of rbcs
tetanospasmin- neuro dysfunction
Clinical findings of C tetani
sardonic grin
trismus (lock jaw)
salivation, dysphagia, rigid gait
progresses to opisthotonus, convulsions, and resp comprimise -> death
Dx of C tetani
CS leukocytosis and LS neutrophilia tachy/bradyarrythmia megaesophagus on rads isolation of bacterium from wound (not likely)
Tx for C tetani
toxin wears off in 3-4 wks, supportive care til then
antitoxin IM (careful of allergic rxns)
Antibiotics (metro, pen G, tetra)
Sedatives, muscle relaxants, antimuscarinics, sx and wound mgt, nursing care
What transmits Mycoplasma haemocanis
brown tick rhiphicephalus sanguineus
What is required before CS develop for M haemocanis
splenectomy
Dx of M haemocanis?
PCR or seeing organism on blood smear
Tx of M haemocanis?
Doxycyline
Dx of Bartonellosis
Serology (only 50%, no good) BacT isolation (PCR)
Tx of Bartonellosis
Doxycycline
Rocky mountain spotted fever
rickettsia rickettsia
monocytotrophic ehrlichiosis
e canis, e chaffeensis
granulocytotrophic ehrlichiosis
e ewingii
granulocytotrophic anaplasmosis
anaplasma phagocytophilum
thrombocytoropic anaplasmosis
a platys
salmon poisoning
neorickettsia helminthoeca
Pathophysiology for Rickettsial Dzs
Rickettsia enters the blood, replicates in endothlial cells -> vascular damage and increase in vascular permeability and leakage of fluids/rbcs into extravascular space
vasculitis leads to decreased platelets and decreased albumin
Vector for e canis or e chaffeensis
rhiphichepalis spp
A equi or A ewingii, cells infected and CS
infected neutrophils
lameness, fever, joint swelling, pain
Vector for A phagocytophilum
ioxdes
A platys cells infected and CS
platelets
usually non clinical but can see cyclic rickettsemia and thrombocytopenia
