Contagious Agalactia in Goat

  • Contagious agalactia (CA) is a disease of sheep and goats. CA may be caused by four different mycoplasma species (Mycoplasma agalactiae (Ma),Mycoplasma mycoides subsp. mycoides LC (Mmm), Mycoplasma capricolum subsp. capricolum (Mcc) and Mycoplasma putrefaciens (Mp). All species contribute significantly to economic losses, particularly in goats ( Nicholas, 1995).

 

Symptoms:

  • Fever
  • Loss of appetite.
  • Other symptoms may include: (Type 1) acute mastitis exhibited as a hot, painful udder producing a greenish-colored, cheesy, pus-like material (chunks) and a watery fluid, with the udder drying up in long-term cases; (Type 2) a cloudy cornea of the eye that may proceed to an ulcer and blindness, although complete recovery usually occurs quickly; and (Type 3) an arthritic form with hot painful, swollen joints that sometimes rupture as an abscess, where the animal may be able to stand if more than one join is involved.
  • Diagnosis is confirmed by laboratory procedures and blood tests.

Transmission:

Mastitis Udder in Goat

  • Spreading may occur when an uninfected goat contacts these secretions.

 

Treatment:

  • Helpful antibiotics are tetracycline or tylosin given intramuscularly (see Therapy and Techniques). The death rate can reach 20% of the infected animals. A vaccine is available in some countries.
