Review of bacterial and viral zoonotic infections transmitted by dogs
Journal of Medicine and Life, 2015
Dogs are a major reservoir for zoonotic infections. Dogs transmit several viral and bacterial diseases to humans. Zoonotic diseases can be transmitted to human by infected saliva, aerosols, contaminated urine or feces and direct contact with the dog. Viral infections such as rabies and norovirus and bacterial infections including Pasteurella, Salmonella, Brucella, Yersinia enterocolitica, Campylobacter, Capnocytophaga, Bordetella bronchiseptica, Coxiella burnetii, Leptospira, Staphylococcus intermedius and Methicillin resistance staphylococcus aureus are the most common viral and bacterial zoonotic infections transmitted to humans by dogs. This review, focused on the mentioned infectious diseases by describing general information, signs and symptoms, transmission ways, prevention and treatment of the infection. As far as the infections are concerned, the increase of the knowledge and the awareness of dog owners and the general population regarding zoonotic infections could significa...
Vector-borne zoonotic pathogens in cats
Biologija, 2019
Cats and dogs are the most popular pets. However, pets can transmit various pathogens and their close proximity to humans may lead to human infections – zoonoses. Transmission of zoonotic pathogens occurs through direct human-animal contact and/or arthropod vectors, such as ticks, fleas, mosquitoes, etc. The emergence of vector-borne zoonotic diseases may occur through international movement of owners with companion animals, which could be infected with pathogens and through spreading and subsequent establishment of disease vectors from endemic to non-endemic areas. The complex ecology of vector-borne zoonotic infections poses both a challenge to and opportunities for surveillance and control. Rising occurrence of vector-borne zoonotic diseases, their relevance to human health, and the relative lack of scientific researches related to feline VBDs point to the necessity to summarize and systemize information on the prevalence of agents of these diseases in populations of domestic cat...

Journal of Feline Medicine & Surgery, 2006
Although cats and their arthropod parasites can sometimes be important sources of zoonotic diseases in humans, the extent of exposure among various cat populations to many potential zoonotic agents remains incompletely described. In this study, 170 domestic cats living in private homes, feral cat colonies, and animal shelters from California and Wisconsin were evaluated by serology to determine the levels of exposure to a group of zoonotic vector-borne pathogens. Serological positive test results were observed in 17.2% of cats for Rickettsia rickettsii, 14.9% for R akari, 4.9% for R typhi, 11.1% for R felis, and 14.7% for Bartonella henselae. Although vector-borne disease exposure has been documented previously in cats, the evaluation of multiple pathogens and diverse cat populations simultaneously performed here contributes to our understanding of feline exposure to these zoonotic pathogens.
Journal of Hospital Infection, 2006
Visitation of hospitalized people by dogs is becoming commonplace, but little is known about the potential health risks of introducing dogs to healthcare settings. This cross-sectional study evaluated the prevalence of zoonotic agents in a group of 102 visitation dogs from a variety of sources across Ontario. Between May and July 2004, owners were interviewed by a standardized questionnaire while dogs underwent a standardized physical examination. One specimen of faeces, hair-coat brushings and one rectal, aural, nasal, oral and pharyngeal swab were collected from each dog and tested for 18 specific pathogens. All dogs were judged to be in good health. Zoonotic agents were isolated from 80 out of 102 (80%) dogs. The primary pathogen was Clostridium difficile, which was isolated from 58 (58%) faecal specimens. Seventy-one percent (41/58) of these isolates were toxigenic. Extended-spectrum beta-lactamase Escherichia coli was isolated from one (1%) dog, extended-spectrum cephalosporinase E. coli was isolated from three (3%) dogs, and organisms of the genus Salmonella were isolated from three (3%) dogs. Pasteurella multocida or Pasteurella canis was isolated from 29 (29%) oral swabs, and Malassezia pachydermatis was isolated from eight (8%) aural swabs. Giardia antigen was present in the faeces of seven (7%) dogs, while Toxocara canis and Ancylostoma caninum were detected in two (2%) dogs and one (1%) dog, respectively. Methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, Campylobacter spp., Microsporum canis, group A streptococci, Pseudomonas aeruginosa and Cryptosporidium spp. were not detected. Further information is needed before the full implications of these findings for infection control can be assessed properly.
Small Animal Zoonoses and Immuncompromised Pet Owners
Topics in Companion Animal Medicine, 2009
This review is a general discussion of common zoonotic infections of companion animals in the United States. Microbes, routes of transmission, and risks to immunocompromised persons are discussed. The primary focus of this article is dogs and cats, although zoonoses of avian, rodent, and rabbit companion animals are discussed in brief. An awareness of zoonoses will allow veterinarians and physicians to collaboratively prevent transmission and treat clinical disease in both human and veterinary patients.
Bacterial canine vector-borne zoonotic diseases in " One Health " concept
Canine vector-borne diseases constitute a large group of diseases transmitted by arthropods with worldwide distribution. A wide range of bacterial, viral, and parasitic agents that are transmitted by vectors cause disease to dogs, many of which can also affect humans and thus have an important zoonotic potential. Bacterial agents that are transmitted by vectors have been considered less important than viral or parasitic agents and are not commonly discussed in companion animal practice. However, close contact between pet animals and people offers favorable conditions for transmission of these bacteria. Many of these diseases have become a focus of interest for scientists in recent years. Increase in reservoir abundance, climate change, changing habitat structure, socio-political changes, and imports of dogs for welfare reasons and trade as well as traveling are considered to be potential factors for the pathogens and vectors introduction into new areas. Apart from, the veterinary aspect of these diseases, domestic dogs could play a central epidemiological role in the transmission of bacterial agents to humans, acting as reservoirs and sentinels, a circumstance that requires a One Health approach. This review highlights the most important of these bacterial agents, presenting updated current knowledge with special reference to treatment approach and One Health aspect.
A Comprehensive Review on Major Zoonotic Parasites From Dogs and Cats
Zoonotic diseases are significant causes of morbidity and mortality in humans and animals, including birds. These diseases are transmitted through several routes and are reported in developing and developed nations of the world. The dogs and cats also act as the reservoirs of a large number of parasitic zoonoses, including toxoplasmosis, giardiasis, leishmaniasis, toxocariasis, and cryptosporidiosis. The roles of pet animals (cats and dogs) in transmitting human infections have been recognized worldwide. Since most of these parasites have an oral-fecal transmission cycle, the transmission of these zoonotic agents could occur through indirect contact with animal feces, contaminated water, and food, or direct contact with infected animals. In addition, the soil is an important route for the transmission of human pathogens. In socioeconomically disadvantaged communities, the poor levels of hygiene and overcrowding, together with a lack of veterinary attention and zoonotic awareness, exacerbate the risks of disease transmission. Traditional husbandry and inadequate management practices, the mixing of wild animals with farm animals, and unrestricted movement and living pastoralists with their animals can all contribute to the development of zoonotic diseases. Therefore, veterinarians are thought to be on the 'front line' of the prevention of pet animal-associated zoonotic parasitic infections.
A Review on Bacterial Infectious Diseases of Dogs
Acta Scientific Veterinary Sciences, 2022
In recent years, the tendency of raising dogs as companion animals has increased in urban and semi-urban settings. Amongst other pathogens viz virus, protozoa, dogs are highly susceptible to diseases of bacterial origin. Bacterial infections in dog causes wide range of illness, ranging from self-limited skin conditions to life-threatening systemic diseases. Some diseases such as brucellosis, leptospirosis, tuberculosis, salmonellosis, and bordetellosis will have a significant influence on the economic status and livelihood of pet owner. These bacterial infections, albeit lethal, can be avoided if intervened earlier, and their impact on humans can be reduced to a greater extent. Here, we reviewed common bacterial diseases of dog and discussed disease etiology, clinical signs, diagnosis, treatment and zoonotic potential. Raising awareness and continuing to educate veterinarians and pet owners about companion animal diseases would not only limit transmission risk but also improve animal as well human health.
Pet husbandry and infection control practices related to zoonotic disease risks in Ontario, Canada
BMC Public Health, 2013
Background: Many human infections are transmitted through contact with animals (zoonoses), including household pets. Despite this concern, there is limited knowledge of the public's pet husbandry and infection control practices. The objective of this study was to characterize zoonotic disease related-husbandry and infection preventive practices in pet-owning households in Ontario, Canada. Methods: A self-administered questionnaire was distributed to individuals at two multi-physician clinics in Waterloo, Ontario, Canada during 2010. One adult from each household was invited to participate in the study. Results: Four hundred one pet-owners completed the questionnaire. Households reported ownership of dogs (68%), cats (48%), fish (13%), exotic mammals (7%), such as hamsters, and reptiles and birds (each 6%). Across all species, individuals at higher risk of infections (i.e. < 5yrs, ≥ 65yrs, immunocompromised) were often (46-57%) present in households. Children < 16 yrs of age had close pet contact, as households reported dogs (13%) and cats (30%) usually slept in a child's bed and dogs often licked a child's face (24%). Household husbandry practices that increase zoonotic disease risk were frequently identified; some fed high-risk foods (i.e. raw eggs, raw meat, or raw animal product treats) to their dogs (28%) or cats (3%); 14% of reptile-owning households allowed the pet to roam through the kitchen or washed it in the kitchen sink. Reported hand washing by children was high for all species (> 76% washed hands sometimes or greater after touching the pet, its feces, or housing), although fewer reported children always washed their hands (3-57%; by species). With a few exceptions, practices were not associated with the presence of higher risk members in the household or recall of having previously received zoonotic disease education. Conclusions: The results suggest there is a need for education on zoonotic disease prevention practices for pet-owning households with individuals at higher risk of infection and those with high-risk species (e.g., reptiles). Further research is needed to determine the role of education in altering higher risk pet practices.
