Abstract:
Ninety-six feral cats from Prince Edward Island were used to determine the prevalence of selected infectious agents. The prevalence rates were 5.2% for feline immunodeficiency virus, 3.1% for feline leukemia virus, 3.1% for Mycoplasma haemofelis, 8.4% for Candidatus Mycoplasma haemominutum, 2.1% for Bartonella spp. and 29.8% for exposure to Toxoplasma gondii. Oocysts of T. gondii were detected in 1.3% of the fecal samples that were collected. Gender and retroviral status of the cats were significantly correlated with hemoplasma infections. Use of a flea comb showed that 9.6% of the cats had fleas; however, flea infestation was not associated with any of the infectious agents.
Insights
Prevalence of infectious agents in Prince Edward Island feral cats was assessed. Feline immunodeficiency virus and Toxoplasma gondii exposure were most common, with no link found between fleas and infections.
Area of Science:
- Veterinary Medicine
- Infectious Diseases
- Feline Health
Background:
- Feral cat populations can harbor and transmit infectious agents.
- Understanding pathogen prevalence is crucial for public health and animal welfare.
- Prince Edward Island's feral cat population health status regarding infectious agents is largely unknown.
Purpose of the Study:
- To determine the prevalence of specific infectious agents in feral cats on Prince Edward Island.
- To investigate potential correlations between infectious agents, cat demographics, and flea infestation.
Main Methods:
- Ninety-six feral cats were sampled from Prince Edward Island.
- Diagnostic tests were performed for feline immunodeficiency virus, feline leukemia virus, hemotropic mycoplasmas (Mycoplasma haemofelis, Candidatus Mycoplasma haemominutum), Bartonella spp., and Toxoplasma gondii exposure.
- Fecal samples were analyzed for T. gondii oocysts.
- Flea combing was conducted, and cat gender and retroviral status were recorded.
Main Results:
- Prevalence rates included: feline immunodeficiency virus (5.2%), feline leukemia virus (3.1%), Mycoplasma haemofelis (3.1%), Candidatus Mycoplasma haemominutum (8.4%), Bartonella spp. (2.1%), and T. gondii exposure (29.8%).
- T. gondii oocysts were detected in 1.3% of fecal samples.
- Hemoplasma infections showed significant correlation with cat gender and retroviral status.
- Fleas were present on 9.6% of cats, but not associated with any tested infectious agents.
Conclusions:
- This study provides baseline data on the prevalence of key infectious agents in Prince Edward Island's feral cat population.
- Feline immunodeficiency virus and Toxoplasma gondii are significant findings.
- While fleas were present, they did not correlate with the tested infections, suggesting other transmission routes may be more important for these agents.
