Bacterial Diseases:
Mycoplasmosis:
*Diagnosis & treatment.
A: DIAGNOSIS:
1- Tentative,,,
-clinical signs & pm lesions:
(infra orbital).
growth.
.
.
.
of production.
until 80%.
2- Confirmatory,,,
➡Samples:
Air sacs, trachea & synovial fluid.
➡Bacteriology:
▶isolation & identification.
➡Histology:
▶Trachea & air sacs ▶High leucocytic infiltration.
➡Serology:
▶RSA, HI & ELIZA.

B: TREATMENT:
Mycoplasma is a mollicute genus of bacteria that lack a cell wall around their cell membranes. This characteristic makes them naturally resistant to antibiotics that target cell wall synthesis (like the beta-lactam antibiotics). They can be parasitic or saprotrophic.
Susceptible to some antibiotics as:
tartrate.
phosphate.
tartrate.
(Doxycycline hyclate).
phosphate.
