Summary
Salmonella bacteria were found in 8% of family dogs in Tehran. One dog owner was also infected with the same Salmonella serotype, indicating a potential pet-to-human transmission risk.
Area of Science:
- Veterinary Medicine
- Zoonotic Diseases
- Microbiology
Background:
- Salmonella infections pose a significant public health concern.
- Pets, particularly dogs, can act as reservoirs for various bacterial pathogens.
- Understanding pathogen transmission dynamics between animals and humans is crucial for disease control.
Purpose of the Study:
- To investigate the prevalence of Salmonella in family dogs in Tehran.
- To determine the potential for Salmonella transmission from infected dogs to their owners.
Main Methods:
- Bacterial cultures were performed on fecal samples from 314 family dogs.
- Environmental and owner samples were collected from households with Salmonella-positive dogs.
- Salmonella isolates were serotyped for comparison between dogs and owners.
Main Results:
- Salmonella was detected in 8 out of 314 (2.5%) dog fecal samples.
- One of the eight dog owners tested positive for Salmonella.
- The Salmonella serotype isolated from the owner matched that of his pet dog.
Conclusions:
- Family dogs in Tehran can harbor Salmonella.
- There is a potential for zoonotic transmission of Salmonella from pet dogs to humans.
- Further research is warranted to assess the extent of this transmission and implement control measures.
