Abstract
Interacting with domestic or feral cats comes with both pleasure and harm. This research has attempted to study the role of cats in Shanghai, China, being vectors of disease and the risk they pose to public health. Polymerase Chain Reaction (PCR), gel electrophoresis, molecular cloning, and DNA sequencing were methods used to compare the prevalence of zoonotic bacteria and parasites in domestic and feral cats. Phylogenetic trees were created for further analysis. From this study involving 30 cats and 12 zoonotic pathogens, four pathogens were identified in our stool samples using PCR: Escherichia coli, Campylobacter spp., Salmonella spp., and Toxocara cati. In total, 60% of the kittens had enteric zoonoses in their stools while 30% of the adult cats’ stools contained enteric zoonoses. Salmonella enterica subspecies enterica, which is the leading cause of Salmonellosis in developed countries, was present in two samples inferred from sequencing and phylogenetic tree analysis.
Highlights
Zoonotic diseases are transmitted by bacteria, parasites, and viruses between vertebrate animals and humans; at least 61% of all human pathogens are zoonoses [1]
The present study aims to determine the prevalence of 12 different zoonotic pathogens in cats and compare them according to two risk factors: age and living conditions in Shanghai, China, with an emphasis on the bacterial zoonosis: Salmonella
Polymerase Chain Reaction (PCR) Analysis: From our positive samples seen in Fig-1, three out of four zoonotic pathogens are bacterial species
Summary
Zoonotic diseases are transmitted by bacteria, parasites, and viruses between vertebrate animals and humans; at least 61% of all human pathogens are zoonoses [1]. The prevalence of zoonotic diseases in urban settings is far more common than we could imagine. Dogs, and house pets are potential reservoirs for a number of zoonoses. Close interactions with these animals significantly increase the risk of humans unknowingly being infected with zoonotic pathogens [2]. The Chinese population rearing cats and dogs as pets has increased due to improvements in overall lifestyle. By 2017, there were at least 53 million pet cats (https://www.mapsofworld.com/world-topten/countries-with-most-pet-cat-population.html) and 27 million pet dogs in China.
