However, recent reports in the veterinary literature of scientifically sound studies have shown that propylene glycol reduces the red blood cell survival time, renders red blood cells more susceptible to oxidative damage, and has other adverse effects in cats consuming the substance at levels found in soft-moist food. [14]
For example, one study showed that a flow velocity in the left heart ear of less than 0.2 m/s was associated with the occurrence of thrombi and spontaneous echocardiographic contrast (smoke). Spontaneous echocardiographic contrast is an aggregation of red blood cells and thus a thrombus precursor that resembles smoke on sonographic imaging. [54]
Haemotoxins, hemotoxins or hematotoxins are toxins that destroy red blood cells, disrupt blood clotting, and/or cause organ degeneration and generalized tissue damage. The term haemotoxin is to some degree a misnomer since toxins that damage the blood also damage other tissues. Injury from a haemotoxic agent is often very painful and can cause ...
These cells are often shades of grayish-blue. Polychromasia is usually a sign of bone marrow stress as well as immature red blood cells. 3 types are recognized, with types 1 and 2 being referred to as 'young red blood cells' and type 3 as 'old red blood cells'. Giemsa stain is used to distinguish all three types of blood smears. [1]
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 a cycle whereby the body destroys its own blood supply (auto-hemolysis). A complete blood count (CBC) may show increased reticulocytes, a sign of increased red blood cell production ...
Kittens obtain the majority of their immune response from the colostrum, and are not born with a strong immune response. When they absorb the mother's antibodies against their blood type it causes lysis of the red blood cells leading to anemia. Symptoms include lethargy, weakness, depression, pale mucous membranes, fever, and blood in the urine.

Now there have been documented cases of cats that get sick and survive the infection and even those that never show clinical signs at all. [2] [5] [9] [10] Cats cannot catch the infection from another cat directly without being bitten by a tick. [citation needed] The life cycle of the protozoa has a tissue phase and an erythrocytic (red blood ...
