Vegetative and heterocyst cells divide labor by exchanging sugars and nitrogen. The bacteria may also enter a symbiotic relationship with certain plants. In such a relationship, the bacteria do not respond to the availability of nitrogen, but to signals produced by the plant for heterocyst differentiation.
Feline disease refers to infections or illnesses that affect cats. They may cause symptoms, sickness or the death of the animal. Some diseases are symptomatic in one cat but asymptomatic in others. Feline diseases are often opportunistic and tend to be more serious in cats that already have concurrent sicknesses.
Not all cats that are infected will have the piroplasms on their blood smear, especially if they are early in disease course. Another method of diagnosing infection in sick cats is to take needle aspirates of affected organs and find the schizonts inside mononuclear cells in the tissues; examination of tissue is also useful for the diagnosis ...
Cat-scratch disease has a worldwide distribution, but it is a nonreportable disease in humans, so public health data on this disease are inadequate. [22] Geographical location, present season, and variables associated with cats (such as exposure and degree of flea infestation) all play a factor in the prevalence of CSD within a population. [23]

Feline infectious anemia (FIA) is an infectious disease found in felines, causing anemia and other symptoms. The disease is caused by a variety of infectious agents, most commonly Mycoplasma haemofelis (formerly called Haemobartonella before Haemobartonella and Eperythrozoon species were reclassified as mycoplasmas).
Damaged cells are cleared by macrophages in the spleen, where the precipitate and damaged membrane are removed, leading to characteristic "bite cells". The denaturing process is irreversible and the continual elimination of damaged cells leads to Heinz body anemia. There are several pathways leading to the hemoglobin damage.
