Treatment for Bovine Papillomatosis
Bovine papillomatosis is a disease of viral origin
Bovine papillomatosis is a disease of viral origin, which needs factors such as epithelial alterations derived from inappropriate alimentation or exploitation of non adapted breeds in tropical climate. There are 3 measures to fight against this disease, as follows:
1. Both alimentation (vitamins, minerals and biotin) and environment, where animals live, must be improved.
2. They must be carried out disinfecting programs for tools and premises, programs for personal hygiene and programs to exterminate insects such as ticks, flies, mosquitoes and gadflies.
3. They must be carried out quarantine programs for the entrance of new animals and programs of healthy guarantee for seminal material, embryos and fertilized ova.
The efficacy of these pharmacologic treatments orally or parenterally has not been contrasted yet. On the contrary, it does has been contrasted its efficacy in treatments for external use based on acid salicylic and formaldehyde associated to proteolytic enzymes. Both acid salicylic and formaldehyde are antiseptic agents, while proteolytic enzymes release dead cells and permit the arrival of antiseptics at infected tissues. These ointments or baths can be successful up to 80% in body warts and up to 60% in breast warts.
It is possible the immunologic prevention of this disease but there are not commercial vaccines available due to the amount of causing viruses. The causing viruses of bovine papillomatosis belong to the family of Papovaviridae where 6 viruses can be found. Among them, the most common ones are PVB Type II and Type III although up to 10 genotypes are known. These viruses enter through epithelial micro injuries, by direct contact or through contaminated material, evading immune system by installing themselves in areas of difficult access for defensive agents, and they also have the chance to keep viable in host.
For this reason, auto vaccines are usually used instead of commercial vaccines. The auto vaccines have been elaborated from the same papilloma. For its way of manufacturing, it is advisable a subcutaneous application with 2 extra vaccinations, one 21 days later and another one 6 months later.
