Serological survey of Neospora caninum and Toxoplasma gondii in cattle ( Bos indicus ) and water buffaloes ( Bubalus bubalis ) in ten provinces of Brazil

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.

Bovine Species

The aim of this study was to evaluate the possible relationships between reproductive parameters and Anti Mullerian Hormone (AMH) levels in two closely related bovine species. AMH levels and the reproductive parameters of 50 water buffaloes (Bubalus bubalis) and 50 Zebu cattle (Bos indicus) of the same age and raised in similar conditions were evaluated. Clinical data were obtained from the farm in specialized designed format, and AMH was measured by ELISA. The results show that Zebu cattle had higher AMH levels than water buffaloes (P<0.0001), while water buffaloes exhibited better reproductive parameters: days open to pregnancy (P<0.0001), parity (P<0.0005), age at first calving (P<0.0001), and intercalving period (P<0.0001). Although both species have different reproductive parameters, no correlations were found between AMH and the reproductive parameters evaluated in either species. Finally, pregnant Zebu cattle and water buffalo showed a tendency to have lower AMH levels than non-pregnant counterparts. The results are paradoxical as the species with lower AMH levels exhibited better reproductive parameters, suggesting that the reproductive parameters within the herd do not depend solely on the ovarian reserve of females.

And Control

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.

Três animais de cada espécie (Bos indicus, Bos taurus e Bubalus bubalis) foram inoculados, via oral, com 2,0 x 10(5) oocistos de Toxoplasma gondii. Seis outros animais, dois de cada espécie, foram mantidos como testemunhas. As alterações clínicas surgidas a partir do 3º dia após inoculação (DAI) foram: hipertermia, taquicardia, taquipnéia, anorexia, prostração, corrimento nasal e lacrimejamento. Estes sinais foram mais evidentes nos taurinos, espécie que apresentou, ainda, diarréia, fotofobia e conjuntivite. Foi possível isolar T. gondii da corrente sangüínea em todas as espécies. Nos taurinos, a partir do 5º DAI até o final do experimento, o parasito foi isolado de todas as amostras de sangue colhidas semanalmente, com exceção do 14º, 35º e 63º DAI. Os bubalinos apresentaram parasitemia no 7º, 14º, 35º e 70º DAI e os zebuínos apenas no 7º e 28º DAI, correspondendo aos picos de temperatura, em todas as espécies, sendo mais evidente em taurinos. Os parâmetros clínico-laboratoriais demonstraram que os taurinos foram mais sensíveis ao T. gondii do que os zebuínos e estes não diferiram significativamente dos bubalinos, que tiveram aparente normalidade clínico-laboratorial.
