“…The frequency of leptospirosis in buffaloes in the state of Paraná found in the present study was 77.17% (213/276), a high result close to the 80% (164/205) found by Viana et al (2009) in Pará and 70.58% (216/306) found by Carvalho et al (2015) in Maranhão. The frequency found was higher than those found in other studies conducted in different states of Brazil, such as 28.5% (35/123) in Pernambuco (Oliveira et al 2018), 27.9% (38/136) in Paraíba (Pimenta et al 2019), 67.7% (86/127) in buffaloes in Pará (Silva et al 2009) or 56.25% (18/32) in Minas Gerais (Mendes et al 2018). It is also important to consider that frequency of leptospirosis can be affected by the number of serovars used in MAT testing (Adesiyun et al 2009).…”

Leptospirosis is a zoonosis that can infect buffaloes and other mammalians, and it’s caused by Gram-negative bacteria of the genus Leptospira spp. The infection occurs through contact with urine or a contaminated environment with the mucous membranes of the animals, and the disease has two phases: leptospiremia and leptospiruria. The objective of this study was to determine the frequency of leptospirosis in buffaloes in the state of Paraná, Brazil, as well as the main serovars present in this area. A total of 276 blood samples were collected from buffaloes from 18 properties located in different cities and mesoregions of Paraná state. A microscopic agglutination test (MAT) was performed to detect the presence of anti-Leptospira spp. antibodies and to identify its serovars. The prevalence was 77.17% (213/276) of buffaloes seropositive for at least one serovar. The most frequent serovar was Icterohaemorrhagiae, followed by the Pomona serovar and serovar Hardjo. This study seems to be the first to determine the frequency of buffaloes with leptospirosis in the state of Paraná. Prevention and control measures are important to control the disease in herds.

“…Anaplasma marginale, Babesia bovis, and Babesia bigemina are important tick-borne agents of cattle worldwide [ 6 ]. Although many studies have been conducted worldwide on the prevalence of these important pathogens in animals, few studies have been conducted on water buffaloes in Latin America [ 7 – 9 ]. The present work aimed to assess the prevalence of N. caninum, T. gondii, A. marginale, B. bovis, and B. bigemina among water buffaloes in the north region of Brazil.…”

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 of Toxoplasma gondii, Neospora caninum, Anaplasma marginale, Babesia bigemina, and Babesia bovis in 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 of T. gondii and N. caninum was 41.3% and 55.5% in ELISA and 35.7% and 48.8% in IFAT, respectively. The overall prevalence of A. marginale, B. bovis, and B. bigemina was 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.

“…Using the IFA, Gondim et al (1999) reported that the positivity rate in Bahia was 3.85% and Fuji et al (2001) observed that the positivity rate in São Paulo was 3.2%. In the state of Pará, Silva et al (2010) reported that the prevalence of infection in buffaloes was 1.1% whereas Silva et al (2013) found a much higher prevalence in this species (41.6%).…”

Toxoplasma gondii is an obligate intracellular protozoan that parasitizes several hosts worldwide, of which cats are definitive hosts. The objective of this study is to evaluate the risk factors associated with the epidemiology of T. gondii in cattle and buffaloes in the state of Pará, Brazil. A total of 2,070 bovine samples (1,749 cattle and 321 buffaloes) were evaluated in 100 rural properties distributed in 51 municipalities from all mesoregions of the state. The evaluated risk factors were animal gender, type of farm, and number of cats in the properties. The serological prevalence of T. gondii was evaluated using the indirect enzyme immunoadsorption assay (iELISA). The samples with a sample/positive (S/P) ratio ? 0.5 were considered positive and analyzed using the indirect immunofluorescence assay (IFA). The samples diluted at 1:64 were considered positive. The chi-square test with a level of significance of 5% and the odds ratio (OR) with a confidence interval of 95% was applied.The data were analyzed using BioEstat software version 5.0.The prevalence of T. gondii in bovines was 35.79% and 45.12% in ELISA and IFAT, respectively. The prevalence was 34.48% and 44.14% in cattle and 42.99% and 50.47% in buffaloes using ELISA and IFA, respectively. The mesoregion with the highest prevalence of infection was Marajó Island, corresponding to 42.86% (129) and 50.5% (152) in ELISA and IFA, respectively. In buffaloes, the prevalence of T. gondiiusing ELISA was higher in males (p < 0.05) in the two age groups. In contrast, the prevalence of T. gondii using IFA was higher in males in the age group 13 to 24 months (p < 0.05). The type of farm did not affect the prevalence of T. gondii in cattle (p > 0.05). However, the presence of cats strongly affected the occurrence of infection in cattle. These results demonstrate the high levels of anti-T. gondii antibodies in cattle and buffaloes in Pará and this may be a public health problem. Furthermore, the presence of cats is a risk factor for infection with T. gondii in these species in Pará.
