“…In this region, serological studies have revealed the presence of anti-Leptospira spp. antibodies in buffaloes, with a prevalence ranging from 34.37 to 80.0% and predominance of the Sejroe serogroup (13)(14)(15), similar to what is observed in cattle. Nevertheless, there have been few studies on leptospirosis in buffaloes; thus, the aim of this study was to detect and perform the molecular characterization of Leptospira spp.…”

In the current context of deforestation and fire in the Amazon, buffaloes could be a cost-effective and sustainable alternative for cattle production in the region, as they can convert low-quality foods and be raised in floodplain areas. However, little is known about the reproductive diseases that affect these animals; thus, the purpose of this study was to perform the molecular characterization of Leptospira spp. in the urogenital tract of water buffaloes (Bubalus bubalis) raised in the Amazon River Delta region in Brazil. Samples were collected from 114 kidneys, 204 ovaries, and 160 uterine swabs of slaughtered buffaloes in the Macapá microregion of Amapá State (Brazil) and were subjected to PCR to detect bacterial DNA. Positive amplicons were sequenced to identify Leptospira species. Among the total samples, 11/473 were PCR positive (2.3%), including 10 kidney samples and one uterine swab sample. DNA sequencing identified two pathogenic species from the kidney samples: L. interrogans, accounting for 60.0% (6/10) of these samples, and L. borgpetersenii, accounting for 20.0% (2/10), while 20.0% (2/10) were identified only at the genus level. The bacterium in the uterine swab sample was identified as L. interrogans with genetic proximity to strains belonging to the serovar Hardjo. This is the first report of leptospires species identified in buffaloes from the Amazon River Delta region and revealed that these animals may be carriers of different pathogenic Leptospira species, similar to bovines, including showing genital colonization.

“…The serovar with the highest frequency among the seropositive buffaloes tested in this study was Icterohaemorrhagiae, with 92.49% of seropositive animals (197/213). This result is considered high when compared to the frequency of the serovar Icterohaemorrhagiae in other studies of leptospirosis frequency in buffaloes in Brazil, where the frequency was 24.5% (53/216) in Maranhão (Carvalho et al 2015), 33.6% (51/152) in São Paulo (Langoni et al 1999) and 5% (2/40) in the city of Belém (Rocha et al 2019). In other countries such as India (21.38%, 46/215) (Alamuri et al 2019), Tanzania (5.26%, 2/38) (Assenga et al 2015), Turkey (1.08%, 1/30) (Kenar & Ozdemir 2013) or Iran (8.1%, 3/37) (Mohammad 2014) the prevalence of serovar Icterohaemorrhagiae was also lower than that obtained in the present study.…”

Serological frequency of Leptospira spp. in buffaloes (Bubalus bubalis) in Paraná state, Brazil

et al. 2023

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.
