Abstract Neosporosis is one of the major parasitic diseases that causes reproductive problems, making it a limitation for optimal efficiency in livestock. The aim of the present study was to conduct a seroepidemiological survey for bubaline neosporosis and to analyse associated factors associated with N. caninum infection in female water buffaloes in the State of Pernambuco, northeast Brazil. The prevalence of N. caninum infection in the bubaline herds examined was 35.4% (122/345; 95% CI: 30.4%-40.7%), at least 1 Neospora-positive animal was found in each farm. Associated factors for N. caninum infection identified in this study were exclusive pasture feeding (OR: 5.91, p <0.001) and purchase of animals of free fair and from reputable sellers (OR: 1.85; p =0.045). In this survey, we document the occurrence of neosporosis in female water buffaloes. Associated factors should be controlled in order to reduce the risk of N. caninum infection in these herds.

Although the largest buffalo herd in the occident is in the north region of Brazil, few studies have been conducted to assess the prevalence of selected parasitic diseases in buffalo herd. The present study was therefore conducted to investigate the epidemiological ofToxoplasma gondii, Neospora caninum, Anaplasma marginale, Babesia bigemina,andBabesia bovisin water buffaloes in the north region of Brazil. A total of 4796 buffalo blood samples were randomly collected from five provinces and simultaneously analyzed by the IFAT and ELISA. The serological prevalence ofT. gondiiandN. caninumwas 41.3% and 55.5% in ELISA and 35.7% and 48.8% in IFAT, respectively. The overall prevalence ofA. marginale, B. bovis, and B. bigeminawas 63%, 25%, and 21% by ELISA and 50.0%, 22.5%, and 18.8% by IFAT, respectively. This study shows valuable information regarding the serological survey of selected bovine pathogens in water buffaloes in the north region of Brazil which will likely be very beneficial for the management and control programs of this disease.

Abstract Neospora caninum is considered to be one of the main causes of abortion among cattle. The present survey was conducted in the municipality of Rolim de Moura, Rondônia State, Brazil. A questionnaire that investigates the epidemiological aspects of neosporosis was used in the analysis of risk factors associated with the animal-level and herd-level prevalence in dairy cattle. A total of 416 bovine blood samples were collected from 30 farms, and N. caninum antibody levels were measured by Indirect Fluorescent Antibody Test (IFAT). Analysis of dairy cattle serum samples revealed the presence of anti-N. caninum antibodies to be 47.36% (n = 197). Risk factors associated with N. caninum infection were the management system and access locations of dogs. The results of the present survey indicated that infection of dairy cattle with N. caninum is widespread in the studied region of Western Amazon, which has implications for prevention and control of neosporosis in this region. Therefore, integrated control strategies and measures are recommended to prevent and control N. caninum infection in dairy cattle. In addition, direct contact between dairy cattle, dogs and wild animals, which can influence the epidemiology of neosporosis, should be investigated further.

One hundred twenty-four water buffaloes (Bubalus bubalis) originating from 9 farms located in southern Italy were tested to investigate simultaneously, for the first time, the seroprevalence of the protozoa Neospora caninum, Toxoplasma gondii and Besnoitia besnoiti by ELISA tests and to evaluate the clinical findings potentially associated to the presence of these aborting parasitic pathogens. Twenty-five of 124 buffaloes (20.2%) were positive for N. caninum, while 17/124 (13.7%) for T. gondii. No buffalo showed specific antibodies for B. besnoiti. Nineteen of 124 animals (15.3%) were found seropositive for both T. gondii and N. caninum. The univariate statistical analysis showed that the seroprevalence of N. caninum is significantly associated with abortion and presence of retained foetal membranes, while the seroprevalence of T. gondii is significantly associated with an increase of days open. The logistic regression models showed that the co-infection by N. caninum and T. gondii strengthened the abortive effects (OR = 7.330) and showed further negative effects on the parameter embryonic death (OR = 2.607). The outcome revealed herein represents a high exposure of N. caninum and T. gondii in water buffaloes with reproduction disorders that deserves attention for both economic reasons, animal health and welfare.
