Tick fever

Local name : Utol, Kato

Transission :
  • The eggs of ticks are laid in the soil and larvae attach themselves to the cattle on which they may develop through one or more nimphal stages before becoming adults.
  • Ticks are caused by blood parasite disease such as "Babesiosis", "Anaplasmosis" or "Tyleriosis"

Recommendation :
  • Application of insecticides either by dipping or spraying. Using ivermectin is ideal application.
  • Reduction of tick population by periodic dipping and spraying, burming of pasture, plowing of fields and rotation of pasture.
@@Plenty ticks are parasitic on cow.

Severe tick infection



Babesiosis

Cause
: Babesia spp.

Transmisson
: ticks as natural vector. Mechanical transmission by biting can occur, however rare case.

Clinical signs and lesions
:
  • Fever, inappetence, depression, weakness, cessation of rumination and severe emaciation.
  • In terminal stage, the respiratory and heart rates are increased, the urine is dark red color and severe anemia occurs.
  • Animals that survive recover gradually from severe emaciation and anemia.

Recommendation
:
  • Control or eradication of vector ticks.
  • Blood transfusion may be necessary in later stages.
  • Consult a venterination for treatment. Anti-babesiosis injection is rarely effective. Oxytetracycline is more effective.

(Microscopic examination)


Anaplasmosis

Cause : Anaplasma marginale

Transission
:
  • Spread from animal to animal through the blood of infected animals with ticks and flies as echanical vector.
  • May also spread mechanically by hypodermic needles and instriments for castration, spaying and dehorning.
  • Recovered animals offten remain carries for life.

Clinical signs and lesions
:
  • Depression, inapettence and elevated temperature.
  • Marked anemia, dehydration and constipation.


Recommendation
:

  • Killing or repelling vectors with chemical dusts and spray.
  • Animals should be dipped, sprayed or dusted at frequent intervais during the vector seasons.
  • Prevent artificial transmission by disinfection used for injection or surgical poeration.
  • Antibiotics (oxytetracycline) may be given.
  • Transfused dextrose or blood that free-blood parasite are effective for improvement lecions.
