Molecular Prevalence and Risk Factors of Campylobacter Infection in Puppies in the Nairobi Metropolitan Region, Kenya. Vet Med Int 2023; 2023:8813405. [PMID: 37089528 PMCID: PMC10118876 DOI: 10.1155/2023/8813405] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 03/23/2023] [Accepted: 03/25/2023] [Indexed: 04/25/2023] Open
Abstract
Campylobacter species are widely distributed pathogens; however, data on its epidemiology in puppies remain scanty, especially in Kenya. A cross-sectional study was conducted in the Nairobi Metropolitan Region to determine molecular prevalence and associated risk factors of Campylobacter species infection in puppies. A total of 260 rectal swabs were collected from puppies from breeding kennels, shelters, and the University of Nairobi Veterinary Teaching and Referral Hospital. The samples were subjected to polymerase chain reaction (PCR) assays for identification of Campylobacter species. Data on potential risk factors associated with puppy exposure were collected using a semistructured questionnaire. Multivariable mixed effects logistic regression analyses were performed with kennels as random effects. Campylobacter species were detected in 64 of the 260 sampled puppies yielding an overall prevalence of 24.6%. Multivariable results showed that puppies from shelters, puppies from kennels that are washed daily, puppies with a recent history of vomiting, and those treated with antibiotics in the past month were significantly associated with the presence of Campylobacter species. Being a kenneled puppy and having had concurrent bacterial infections were identified as protective factors. This study provides molecular evidence of puppy exposure to Campylobacter species which could have impact on puppy health and highlights the need to develop awareness and management strategies to potentially reduce the risk of transmitting this pathogen among puppies, to humans, and other animals.

Yan B, Li Y, Qin Y, Yan J. Spatial layout planning of the pig northward movement based on GIS. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2021; 28:41051-41060. [PMID: 33774794 DOI: 10.1007/s11356-021-13357-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Accepted: 03/04/2021] [Indexed: 06/12/2023]
Abstract
This study aimed to optimise the layout of pig breeding in the south water network area and guide the transfer of pig production capacity to the areas with large environmental capacity and the main maize-producing areas. Combining with the alarm value of equivalent pig manure load on cultivated land, the comprehensive advantage index of maize and GIS (Geographic Information System), this study analysed the spatial layout planning of the pig northward movement in China. Results showed that the alarm value of equivalent pig manure load on cultivated land in other parts of the study area exceeded 0.40, except in Jilin, Heilongjiang and the Inner Mongolia Autonomous Region. The highest alarm value of equivalent pig manure load on cultivated land value of 1.96 was observed in Fujian Province, followed by Jiangxi (1.09) and Hubei (0.42). A total of 573.996 million excess pig equivalents were present in the study area. In the provinces with potential pig equivalent, Jilin, Heilongjiang and the Inner Mongolia Autonomous Region can carry the potential pig equivalent of 306.270 million. The priority target areas of the pig northward movement were Jilin, Heilongjiang and the Inner Mongolia Autonomous Region according to the comprehensive advantage index of maize. Combining with the spatial analysis method of GIS, the scheme of the pig northward movement was obtained. According to the spatial layout planning of the pig northward movement, Jilin and Heilongjiang carried 15.339 and 135.36 million pig equivalents, respectively, thereby reaching the maximum number of pig equivalents they can carry, whereas the Inner Mongolia Autonomous Region can carry 80.086 million pig equivalents. The results can provide a scientific basis for the spatial layout planning of pig breeding and environmental pollution protection in China.

Santaniello A, Varriale L, Dipineto L, Borrelli L, Pace A, Fioretti A, Menna LF. Presence of Campylobacterjejuni and C. coli in Dogs under Training for Animal-Assisted Therapies. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:3717. [PMID: 33918252 PMCID: PMC8038157 DOI: 10.3390/ijerph18073717] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Revised: 03/28/2021] [Accepted: 03/31/2021] [Indexed: 12/21/2022]
Abstract
This study was conducted to evaluate the presence of Campylobacter (C.) jejuni and C. coli in dogs at five dog training centers in Southern Italy. A total of 550 animals were sampled by collecting rectal swabs. The samples were processed to detect thermotolerant Campylobacter spp. by culture and molecular methods. Campylobacter spp. were isolated from 135/550 (24.5-95% confidence interval) dogs. A total of 84 C. jejuni (62.2%) and 51 C. coli (37.8%) isolates were identified using conventional PCR. The dog data (age, sex, breed, and eating habits) were examined by two statistical analyses using the C. jejuni and C. coli status (positive or negative) as dependent variables. Dogs fed home-cooked food showed a higher risk of being positive for C. jejuni than dogs fed dry or canned meat for dogs (50.0%; p < 0.01). Moreover, purebred dogs had a significantly higher risk than crossbred dogs for C. coli positivity (16.4%; p < 0.01). This is the first study on the prevalence of C. jejuni and C. coli in dogs frequenting dog training centers for animal-assisted therapies (AATs). Our findings emphasize the potential zoonotic risk for patients and users involved in AATs settings and highlight the need to carry out ad hoc health checks and to pay attention to the choice of the dog, as well as eating habits, in order to minimize the risk of infection.
