Case: A cat named mike was diagnosed with Feline Hemoplasmosis.

Vital Signs Presentation:
Severe dehydration, severely pale mucous membranes, depression, hypothermia, tachycardia, tachypnea, severe runny nose, blepharospasm (spasms of the eyelids), conjunctival oedema (swelling of the conjunctiva), severe perforated corneal ulcers

Clinical Diagnosis:

Ultrasound: rapid detection of splenomegaly and mild hepatic steatosis.
CBC findings:
Haemoglobin (HB): 1.8 g/dL
Haematocrit (HCT): 5.3%
Blood smear: positive for mycoplasma.
Slide agglutination test: positive, indicating secondary immune-mediated haemolytic anaemia (IMHA).

I. Definition of the disease and types of pathogens
Pathogen:

Main types:
Mycoplasma haemofelis (strongly pathogenic, parasitises the surface of erythrocytes and causes severe haemolysis);
Candidatus Mycoplasma haemominutum (weakly pathogenic, often latent infection);
Candidatus Mycoplasma turicensis (intermediate pathogenicity).
Routes of transmission: flea bites (primary), bites, blood transfusions, vertical transmission.
Pathogenesis:

Mycoplasma destroys erythrocyte membranes → intra- and extravascular haemolysis → secondary immune-mediated haemolysis (IMHA) → anaemia, tissue hypoxia.

Emergency treatment protocol in the absence of blood chemistry analysis
1. Core treatment goals:

Correction of anaemia: enhance oxygen-carrying capacity;
Clear pathogens: control mycoplasma proliferation;
Suppressing immune destruction: blocking the IMHA vicious cycle.

Emergency treatment protocol in the absence of blood chemistry analysis
1. Core treatment goals:

Correction of anaemia: enhance oxygen-carrying capacity;
Clear pathogens: control mycoplasma proliferation;
Suppression of immune destruction: blocking the IMHA vicious cycle.

2. Treatment protocol:
Whole blood transfusion (after crossmatching), target HCT ≥ 15%
Antibiotics to control pathogen proliferation
Management of complications such as corneal ulcers routine treatment

After 10 days of treatment, Mike’s body is stable, showing vigour and in good condition, with all indicators up to standard
