“…In Brazil the occurrence of dogs presenting antibodies against of Leptospira spp. varies widely, ranging from 7.1% to 73.3%, and the most frequent serovars observed in the present study are consistent with those found in other investigations (FONZAR;LAVINSKY et al, 2012;LILENBAUM, 2013;MORIKAWA et al, 2015). Although reactions to serovar Butembo have not frequently been found in dogs in recent years, they were found in bovines of some regions of Brazil, mainly in the State of Santa Catarina, and the occurrence of cross infection between dogs and cattle may be possible (TONIN et al, 2010).…”

“…Many serological studies performed in dogs in Brazil have shown the variability of the distribution of predominant Leptospira serovars in different locations. The most frequent are Autumnalis, Icterohaemorrhagiae, Copenhageni, Canicola, Pyrogenes, and Castellonis (BATISTA et al, 2005;FONZAR;MORIKAWA et al, 2015;). In the state of Piauí, north of Brazil, there are many reliable studies of leptospirosis in bovines (MINEIRO et al, 2010), swines (GONÇALVES et al, 2011, and ovines (CARVALHO et al, 2011).…”

A leptospirose é uma doença sistêmica causada por bactéria Leptospira spp. que afeta seres humanos, animais domésticos e selvagens. O presente trabalho investigou a presença de anticorpos anti-Leptospira spp. na população canina da cidade de Teresina-Piauí, e os respectivos sorovares predominantes. Amostras de sangue de 425 cães foram coletadas no Centro de Controle de Zoonoses de Teresina, no período de julho de 2010 a janeiro de 2012, e submetidas à prova de Soroaglutinação Microscópica (SAM). Este estudo encontrou uma taxa de infecção média com 17,41% (IC 95%; 13,8 – 21,0) e 11 sorovares reagentes, sendo os prevalentes Canicola (18,9%), Autumnalis (16,2%), Icterohaemorrhagiae (12,1%) e Butembo (12,1%). As questões levantadas neste estudo indicam a ocorrência de infecção por Leptospira spp em cães da cidade de Teresina-Piauí, Brasil.

“…The southern regions of China have many major rivers and lakes, and abundant water energy resources. This area also contains a large number of ponds and small lakes, which are often contaminated by animal carriers that excrete pathogenic leptospires (Zhang, Wang, et al, ; Zhao et al, ). Previous reports showed that the leptospirosis has been considered as a neglected zoonosis associated with infrastructure problems and low socioeconomic status, particularly in slums and rural areas (Morikawa et al, ; Pellizzaro et al, ). Farmers engaged in rice cultivation, field management and animal herding are highly vulnerable to contracting leptospirosis (Suárez et al, ).…”

Leptospirosis is one of the most common and neglected tropical waterborne diseases in China, causing serious economic losses, and constituting a significant public health threat. Leptospirosis has recently received increased attention and is considered a reemerging infectious disease in many countries. The incidence of leptospirosis among people suggests that occupation, age, season, sex and water recreational activities are significant risk factors. The aim of this study was to describe the epidemiological profiles of leptospirosis in China during the 2007-2018 period. The morbidity data of leptospirosis by age, season (month), gender, occupation and geographic location (different provinces) were obtained from the public health science data centre of China for subsequent epidemiological analysis. The results indicate that the incidence of leptospirosis has shown a slow downward trend from 2007 to 2018, but morbidity rates were still relatively high (0.0660-0.0113). The incidence of leptospirosis varied in different provinces of China; cases localized mainly to the Southern and Central provinces, areas with warm weather and ample rainfall. Older people (aged 60-75), males, farmers, students and field workers were high-risk populations. During the 2007-2018 observation period, morbidity rates increased beginning in May, remained at high levels in August and September and decreased after November. The present investigation highlights the re-emergence of leptospirosis in some provinces of China (especially in Yunnan and Fujian) and shows that leptospirosis remains a serious public health threat. The results of this study should enhance measures taken for the prevention, control, and surveillance of leptospirosis in China.

“…In other regions of the country wild animals and dogs also showed higher occurrence than in the present study, such as dogs studied in the state of Paraíba [4] with 21.4% (61/285) seropositivity, Rio Grande do Norte with 6.8% (25/365) [9], Paraná with 11% per dog-trimester [27], and Pará with 17.15% (47/274) [31]. In two semi-arid regions of Brazil the seropositivity was 5.6% (10/180) in dog and 3.9% (6/152) in wild mammals [34].…”

Frequency of anti-Leptospira spp. antibodies in dogs and wild small mammals from rural properties and conservation units in southern Brazil

et al. 2019

Leptospirosis is a disease of worldwide distribution that affects man and several animal species. Domestic and wild animals can behave as reservoirs of the agent. The aim of this study was to evaluate the frequency of anti-Leptospira spp. antibodies in dogs and wild small mammals from rural properties and conservation units of three municipalities of Rio Grande do Sul State, Brazil. Sera were collected from 192 domestic dogs and 132 small mammals, namely rodents of the Cricetidae and Caviidae families and marsupials of the Didelphidae family. The study used Microscopic Agglutination Test (MAT) against 23 serovars of Leptospira spp. Overall, 9.90% (19/192) dogs, and 1.51% (2/132) small mammals were seropositive. Leptospira interrogans serovar Australis was the most frequent serovar in dogs and antibodies against L. interrogans serovar Pomona were detected in a dog and a small mammal belonging to the same municipality. We conclude that in the regions studied the frequency of seropositivity in dogs is low, and leptospires do not seem to be circulating in small mammals, yet, further research is necessary to assess the real role that these animals may have for leptospirosis in the studied areas. This is the first serological survey in small mammals, including wild rodents, in the area that encompasses conservation units of great importance to Rio Grande do Sul state.
