My cat was diagnosed with Feline Hemotropic Mycoplasmosis today. It is caused by this species of parasite of the red blood cells. The diagnosis was made by my vet after weeks of trying to treat and figure out the cause of her anemia and weight loss. Today the diagnosis was made when her blood was examined under a microscope. The photo I am using just to document this was taken from wikipedia. I have no idea how this could be better documented although I will ask if by chance, he took a photo of the blood smear under the microscope when I take her back for another cbc in 2 weeks. I don't see any observations for this in iNat and felt there should be. My cat's name is Sasha.

Photo removed, waiting to get something from the vet.
update: When I took my cat back for her recheck after completing the antibiotic, the labs were rerun, and she was weighed. She is starting to gain the weight back & she is no longer anemic. I am attaching a letter from the vet with her official diagnosis he made after examining her blood under a microscope, plus her before and after labs and a photo of her.
I am doing all this to document the fact that here in Garland, part of DFW in Texas, we have this parasite, (the living organism) which is carried by fleas and causes this serious, can be fatal, disease in felines. It has not been documented in iNat and I think it should be.

This is Mycobacterium gordonae, an uncommon cause granulomatous inflammation of the lung. This 75 year old man was realtively immunocompromised because of Chronic Lymphocytic Leukemia. He had a lung mass that by CT and PET scans was suspicious for cancer which prompted surgery to remove a wedge of his lung. On intraoperative frozen section, where the pathologist provides a diagnosis during surgery, cancer was not confirmed. Rather it showed granulomatous inflammation. If it has shown cancer, then the surgeon would have done a completion lobectomy. These final sections show granulomatous inflammation with caseous necrosis and giant cells. The last slide is a an acid fast stain. The arrow points to beaded organisms that stain red ( better seen through the microscope ). Culture of the material grew M. gordonae, which is a relative of the organism that causes tuberculosis.

Colonies of M. tuberculosis (10×) isolated (on Middlebrook/7H11 agar) from a sputum sample of a TB positive patient. Note the characteristic cording/coiling morphology of the colonies.
The sample was confirmed positive by PCR (GeneXpert) and acid fast staining (auramine O).
