In cats, the antibodies are already present in the mother's blood before parturition. The blood group antigens are similar in structure to the antigen of a common bacteria in the gut of cats leading to antibody formation. Kittens obtain the majority of their immune response from the colostrum, and are not born with a strong immune response.
Autoimmune hemolytic anemia (AIHA) is an autoimmune disorder which occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst , leading to an insufficient number of oxygen-carrying red blood cells in circulation . The lifetime of the RBCs is reduced from the normal 100–120 days to just a few days in ...

Spherocytes are found in immunologically-mediated hemolytic anemias and in hereditary spherocytosis, but the former would have a positive direct Coombs test and the latter would not. The misshapen but otherwise healthy red blood cells are mistaken by the spleen for old or damaged red blood cells and it thus constantly breaks them down, causing ...
Mixed autoimmune hemolytic anemia (MAIHA) is a type of autoimmune hemolytic anemia which combines the features of cold sensitive antibody-induced diseases and warm autoimmune hemolytic anemia. The work-up for diagnosis is complex and the condition can be over-diagnosed. [1] [2] [better source needed]
Treatment depends on the type and cause of the hemolytic anemia. [ 2 ] Symptoms of hemolytic anemia are similar to other forms of anemia ( fatigue and shortness of breath ), but in addition, the breakdown of red cells leads to jaundice and increases the risk of particular long-term complications, such as gallstones [ 4 ] and pulmonary ...
About half of the cases are of unknown cause, with the other half attributable to a predisposing condition or medications being taken. Contrary to cold autoimmune hemolytic anemia (e.g., cold agglutinin disease and paroxysmal cold hemoglobinuria) which happens in cold temperature (28–31 °C), WAIHA happens at body temperature.

Despite the presence of antibodies, the immune system fails to control the virus, resulting in severe clinical outcomes, including lymphoma, leukemia, fibrosarcomas, various anemia (immune-mediated hemolytic anemia, aplastic anemia, pure red cell aplasia), reproductive issues, neurological disorders, gastrointestinal disease and other (e.g ...
