IMHA
Spherocytes can be seen in horses with what infection?
Clostridial infections
What do IMHA animals usually die of?
Thromboembolism
How do you treat IMHA?
Glucocorticosteroids, fluids
Direct antiglobulin test done to detect IMHA as long as agglutination is not present
Coomb’s test
Maternal antibodies against neonate’s blood group antigen
Neonatal isoerythrolysis
Which erythrocyte parasites cause intravascular hemolysis?
Babesia and Theileria
Common, serous cause of severe anemia in cats that is transmitted horizontally and vertically
Mycoplasma haemofelis
How do you treat Mycoplasma haemofelis infection?
Doxycycline for 3 weeks
Causes severe anemia in baby pigs and is assoc. w/poor weight gain in adult pigs
Mycoplasma haemosuis
How do you treat baby pigs with M. haemosuis?
Long-acting oxytetracycline
Tick-borne rickettsial infection that can cause fatal hemolytic anemia d/t immune-mediated destruction
Anaplasmosis
Causes severe disease and hemolytic anemia and is commonly mistaken for IMHA
Babesiosis
How do you treat Babesiosis?
Imidocarb disproprionate
Protozoans that cause hemolytic anemia in ruminants
Theileriosis
Piroplasm lives in RBCs of ruminants
Theileriosis
Protozoan of cats transmitted by ticks and almost always fatal
Feline cytauxzoonosis
