Rhipicephalus sanguineous
what are the clinical signs of acute phase ehrlichiosis?
vague (lethargy, fever weight loss)
lymphadenopathy and splenomegaly
thrombocytopenia (and leukopenia)
what are the clinical signs of chronic phase ehrlichiosis?
vague (fever, lymphadenopathy, splenomegaly, PUPD)
petechia/epistaxis (thrombocytopenia)
what are the clinico-pathological changes seen with ehrlichiosis?
pancytopenia (non-regenerative anaemia)
moderate/marked lymphocytosis
proteinuria
what is found on cytology of patients with ehrlichiosis?
morula within monocytes
what test can be used to test for a range of vector borne disease?
4dx snap test
what is used to treat ehrlichiosis?
doxycycline (works rapidly)
what ticks transmit anaplasmosis?
Ixodes ricinus
Rhipicephalus sanguineous
what are the clinical signs of anaplasmosis?
non-specific (fever, lethargy, lameness, splenomegaly, thrombocytopenia)
how is anaplasmosis treated?
usually self-limiting
what are the clinico-pathological changes seen with anaplasmosis?
pancytopenia
what is seen on cytology of animals with anaplasmosis?
morula within neutrophils
what diseases does the 4dx snap test test for?
anaplasmosis
ehrlichiosis
lyme disease
Dirofilaria immitis
what is used to treat anaplasmosis?
doxycycline (rapid improvement)
what tick transmits rickettsiosis?
Rhipicephalus sanguineous
what are the clinical signs of rickettsiosis?
fever, oedema, erythema, lameness, lymphadenomegaly, thrombocytopenia
what is used to treat rickettsiosis?
doxycycline
what tick transmits Lyme disease?
Ixodes ricinus
what are the clinical signs of Lyme disease?
polyarthritis
nephritis (protein losing nephropathy)
what is done to diagnose Lyme disease?
clinical signs and antibodies
4dx snap test
if serology tests for lye disease are positive, what should be tested next?
check proteinuria
check co-infections
what is used to treat Lyme disease?
doxycycline
what ticks transmit babesiosis?
