Guinea Pig Coccidiosis is a serious Gastro Intestinal condition which needs prompt treatment. Failure to treat will lead to death within a matter of days and must not be ignored.

Once an animal is infected the oocyts will sporalate and rapidly produce in large numbers. This means that the intestinal cells inside the animal will rapidly become infected as the spores grow. Within a short period of time thousands of cells can become infected and destroyed. Due to the destruction of the cells within the instines will cause disrupted function in the intestines.

Coccidiosis Spores/Ooccyts can remain the environment for many years and are difficult to eradicate as they are resistant to most forms of sterilisation including burning. If you have had a Guinea Pig that has carried Coccidiosis the only confirmed method of killing the Bacteria/Spores is by thoroughly sterilising your Guinea Pigs enclosures and any other items it may have come in to contact with. A Bacterial Cleaner like Anigene will work rather then Risking Bleech. You will need to :-

  • Wash the Cage
  • Wash Housing
  • Wash Water Bottles
  • Wash Food Bowls
  • Dispose of any Toys (Tubes, Cosy Beds, Wood Chews) and replace with New.

Insure that if you have other Guinea Pigs in separate housing to infected Guinea Pigs you will need to ensure you Wash Hands/Clothing prior to handling un-infected Guinea Pigs.

In fact it is recommended that you handle un-infected Guinea Pigs 1st and hold Infected Guinea Pigs Last.

It is Recommended that if a Guinea Pig has been Confirmed as Having Coccidiosis then

ALL Guinea Pigs should be treated as a preventative measure.
