In veterinary science, there is little research about owners' perceptions of pet health and parasitic infections/infestations, despite the risk of transmission of zoonotic pathogens by ectoparasites. This study investigated the effects of demographic factors on pet owner's perception of ectoparasite infestation risk and behaviours related to animal health in southeast Queensland, Australia employing the Health Belief Model (HBM). A total of 241 dog owners were surveyed in 2018. The electronic survey was generated through SurveyMonkey and distributed utilising UQ SVS and Royal Society for the Prevention of Cruelty to Animals (RSPCA) email networks, informative posters and brochures placed in selected veterinary clinics, and in-person visits to dog parks. The relationship between dog owners' perception of flea and tick infestation risk was assessed using an adaptation of the Health Belief Model, social cognitive framework for health protection. Most survey respondents were between 26 and 45 years of age (40%), identified themselves as females (83%) and had a bachelor's degree (43%). Our results indicate that female owners had greater level of health concern related to ectoparasites compared to males. Similarly, owners aged 18 to 25, with a grade 10 to 12 level of attained education and living predominately in a rural setting showed greater level of health concern related to ectoparasite infestations. The results also indicated that cat owners had on average, higher levels of health concern than dog owners. Our study indicates that the perceptions of pet owners towards perception of flea and tick infestation risk varies demographically, and owner education is an important predictor of prevention behaviours towards tick and flea infestation of pets.</p></div>","PeriodicalId":23600,"journal":{"name":"Veterinary parasitology, regional studies and reports","volume":"54 ","pages":"Article 101087"},"PeriodicalIF":1.4,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141844520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodology was based on a questionnaire survey conducted in 37 villages and coprological analysis using the McMaster method on faecal samples from 968 small ruminants, including 555 goats and 413 sheep. Multiple logistic regression was used to highlight the risk factors associated with each type of parasitosis encountered. The results showed that the most widespread farming system remained 100% traditional, with feeding based essentially on natural grazing. Coprological results showed the prevalence of nematodosis (70.2%), Cestodosis (4.1%) and Coccidiosis (79.9%), with an average prevalence of coinfection of 56.9%. These parasite loads were significantly higher during the rainy season and in the more arid northern Sahelian zone, with a marked reduction at the end of the season. Average parasitic egg excretions were 1089 EPG of nematodes and 6864 EPG of coccidia. Parasite loads were higher in the wetter southern strip and varied significantly by breed. Of the five breeds of small ruminants studied, the ara-ara sheep had the highest parasitic loads and prevalences for nematodosis (78.6%), coccidiosis (89,3%) and coinfection (70.9%), appears to be the most susceptible to parasitosis. As for risk factors for severe parasite pressure, animals at the end of the rainy season, older animals and those with poor body condition were at risk of nematodiasis or coinfection. On the other hand, animals at the beginning of the rainy season, farms located in less arid southern Sahelian zones and male subjects were the groups at significant risk of coccidiosis.
