Hello. My guinea pig has cystitis, she squeaks when she goes to the toilet and there is blood in her urine. The doctor took a urine culture and it was found out that the infection is caused by the bacterium “enterobacter cloacae”. The results of the culture showed that the bacterium is sensitive to antibiotics: amikacin and meropenem. The doctor says that none of these antibiotics can not be used for guinea pigs, they cause enterotoxemia. Is this true? I have read that amikacin is still used to treat guinea pigs. I live in a big city but only one clinic treats rodents, unfortunately in my country there are few places that treat rodents at all. Perhaps among you there are doctors or owners of guinea pigs who have faced a similar problem. Please tell me more about the antibiotics mentioned above, all the risks and whether I have any chance to cure my baby.
