4. canine and feline blood groups

Question 1

how many antigens the dog have?

Answer 1

14 antigens

Question 2

how many antigens the cat have?

Answer 2

2 antigens

Question 3

what are the most frequent blood groups antigen in the dog?

Answer 3

DEA 1.1 (40%), DEA 1.2. (20%), DEA 4 and DEA 7

most of the dogs have DEA 4 antigen

Question 4

if a DEA 1.1 negative dog gets a transfusion of DEA 1.1 positive blood for the second time

Answer 4

a so-called late type hemolysis occurs in 1 or 2 weeks

Question 5

if a DEA 1.1 negative dog gets a transfusion of DEA 1.1 positive blood for the third time

Answer 5

acute (<12 hours) transfusion reaction takes place that may be lethal

Question 6

DEA 1.2 incompatibility leads to?

Answer 6

moderate transfusion reactions

Question 7

DEA 1.3 antigens sensitizes the individual against ?

Answer 7

DEA 1.3, DEA 1.1 and DEA 1.2 as well

Question 8

what are the blood group antigens of the cat?

Answer 8

there are type A and B blood group antigens

Question 9

if a type B cat gets type A or AB

Answer 9

blood a fatal transfusion reaction will occur within 24 hours because the blood plasma of cats that have type B blood group contains large amount of anti A antibodies

Question 10

if a type A cat gets type B or AB blood

Answer 10

late type hemolysis or acute reaction will occur

Question 11

cats that have type AB blood group should be given

Answer 11

type AB (rare blood group in cats) or type A (contains just a few anti-B antibodies) blood

Question 12

5-20 ml depending on the body weight of the recipient) and after 5 minutes general reactions, pulse rate, and pulse quality are observed. Restlessness, shivering, elevated pulse and respiratory rate, dyspnoea, urination, defecation, and vomiting may refer to incompatibility. If there are no abnormal reactions, the full transfusion can be given after 10 minutes.
