Species
Feline Tritrichomonas blagburni (most prevalent) Pentatrichomonas hominis Must be differentiated by careful morphological comparisons or PCR (most commonly done by the latter method) Canine Pentatrichomonas hominis (most prevalent) Tritrichomonas blagburni (rare) Must be differentiated by careful morphological comparisons or PCR (most commonly done by the latter method) Pentatrichomonas hominis may or may not be associated with clinical disease. The remainder of this guideline focuses on the pathogenic T. blagburni .
Disease
Many cats are asymptomatic carriers and are free of any clinical signs even though they may test positive by PCR or other methods. Most infected cats, although beset with chronic loose stools, often remain active, playful, and do not lose weight.
Prevalence
A survey of 117 cats from 89 catteries revealed the prevalence of T. blagburni at 31% among cats (36 out of 117) and catteries (28 out of 89) based on results of fecal smear examination, fecal culture, or PCR diagnosis.
Diagnosis
Diagnosis of T. blagburni may be achieved via observation of organisms in a direct fecal smear, after culturing in media, or via PCR. Tritrichomonas blagburni is often microscopically misdiagnosed as Giardia spp., but the movement of the organism is quite different.
Treatment
There is no approved treatment for feline or canine trichomoniasis , however, several drugs have demonstrated efficacy against feline T. blagburni in the research laboratory. Treatment failures are common and drug efficacy can be inconsistent.
Control and Prevention
It is best to keep infected cats away from other cats, limiting contact as much as possible and not allowing them to share a litter box. Cleaning the litter box often to limit reinfection.
Public Health Considerations
Tritrichomonas blagburni is not considered a zoonotic agent
