Mycotic Placentitis

There are 35 species of fungus which can cause abortion but in cow 60 % cause is Aspergillus fumigatus then Absidia Ramosa, and Corymliferia. These are common.

Occurrence is by respiratory tract and ingestion of contaminated feed. The ulcerative lesions in the stomach will develop; also in abomasum. Within next 20-80 days the abortion may occur. Organism is present in placenta, fetus, and amniotic fluid.

Lesions:
Placentits, yellowish thick material in inter cotyledonary space, swelling of cotyledon. There are diffused white-grey hair patches at neck region, thoracic cavity and on thigh region of fetus.

Source:
Source is mouldy hay, rice straw, wheat straw, and poor quality silage specially where storage conditions are not favorable i.e. more humidity.

Contributory Factors:

  • Improper housing conditions

  • More number of animals in less area. One infected will lead to infection of all animals.

  • Contamination of food

  • Rainy season

  • Abortion occurs at 3-7 month of pregnancy.

Control:

  • Maintain quality of hay, silage, and straw

  • Fungicidal spray

  • Proper housing

Diagnosis:
Aborted fetus and placenta is send to lab for the isolation of microorganism

The food analysis is important for fungal spores and toxins.

Treatment:
Separate the infected animals. Give progesterone.
