“…Our findings are apparently lower than the reported seroprevalences among dogs in Europe. Previous studies in Spain reported seroprevalence values of 3.1-19.2% in Spain [37], 6.4-46.7% in Italy [38], 58.3% in Greece [39], 20.7% in Turkey [40], 17.9% in Albania [41], 2.1% in Romania [42], 0.9-10.1% in Germany [43], 11.1% in Serbia [44] and 29.8% in public shelter and 12.3% owned dogs, in Montenegro [45].…”

A cross-sectional study was conducted to gain insight into the epidemiology of canine ehrlichiosis and rickettsiosis in northern Portugal. Specific IgG antibodies to Ehrlichia canis were analysed using a commercial indirect ELISA test, and antibodies to Rickettsia conorii using a commercial IFAT. A total of 113 dogs from two different shelters were sampled, and seroprevalence values of 0.9% (95% confidence [CI]: 0.2–4.8%) for E. canis and 9.7 (95% CI: 5.5–16.6%) for R. conorii were found. Univariable models investigated risk factors for seropositivity. The odds ratios (OR) of R. conorii seropositivity were higher for female dogs (OR = 2.32; 95% CI: 1.58–3.39) and for dogs belonging to Shelter 2 (OR = 3.0; 95% CI: 2.28–3.95). Seropositive dogs for co-infection (E. canis + R. conorii) were more frequently observed in females (OR = 2.4; CI 95%: 1.66–3.47) and in Shelter 2 (OR = 2.72; 95% CI: 1.97–3.76). These findings show that shelter dogs in northern Portugal are exposed to E. canis and R. conorii, which can affect both canines and humans. It is imperative to adopt a One Health approach to educate the public about the hazards of canine zoonoses and develop legislation and procedures to control their spread and preserve public health.

A cross-sectional study was conducted to gain insight into the epidemiology of canine ehrlichiosis and rickettsiosis in northern Portugal. Specific IgG antibodies to Ehrlichia canis were analysed using a commercial enzyme-linked immunosorbent assay (ELISA), and antibodies to Rickettsia conorii were analysed using a commercial indirect immunofluorescence antibody test (IFAT). A total of 113 dogs from two different shelters were sampled, and seroprevalence values of 0.9% (95% confidence (CI): 0.2–4.8%) for E. canis and 9.7 (95% CI: 5.5–16.6%) for R. conorii were found. Multiple logistic regression investigated risk factors for seropositivity. The odds ratios (ORs) of R. conorii seropositivity were higher for female dogs (OR = 6.429; 95% CI: 1.201–34.407). Dogs seropositive for co-infection (E. canis + R. conorii) were more frequently observed among females (OR = 7.606; CI 95%: 1.478–39.132) and in Shelter 2 (OR = 18.229; 95% CI: 2.190–151.756). These findings show that shelter dogs in northern Portugal are exposed to E. canis and R. conorii, which can affect both canines and humans. It is imperative to adopt a One Health approach to educate the public about the hazards of canine zoonoses and develop legislation and procedures to control their spread and preserve public health.

“…As espécies destes grupos são os agentes patogênicos, transmitidos por carrapatos Rhipicephalus sanguineus (3,4), mais comuns em cães no mundo inteiro (5,6,7). A distribuição e a transmissão geográfica estão principalmente relacionadas a este vetor (8). São os agentes causadores de condições patológicas chamadas de erliquiose monocítica canina (EMC) e trombocitopenia cíclica canina (TCC) (9).…”

No Brasil, as infecções por hemoparasitas representam uma das principais causas de busca por assistência veterinária em cães. Infecções por bactérias da ordem Rickettsiales que incluem Ehrlichia sp. e Anaplasma sp. tem uma grande participação nessas buscas. Foi objetivo deste estudo elucidar aspectos epidemiológicos regionais e hematológicos de infecções por Anaplasma sp. e Ehrlichia sp, muitas vezes assintomáticas, em cães no município de Jataí-GO. Os dados deste estudo foram baseados em amostras de sangue de cães atendidos no Hospital Veterinário da Universidade Federal de Jataí, em Jataí, Goiás, entre os anos de 2005 e 2017. A observação microscópica da presença de mórulas de Ehrlichia sp. e Anaplasma sp. foi utilizada como critério de positividade. 5.015 animais foram atendidos nesse período e 691 (13,78%) deles foram positivos para a presença destes hemoparasitas. Entre esses animais, 9,23% (463/5015) possuíam mórulas de Ehrlichia sp., e 4,37% (219/5015) apresentavam mórulas típicas de Anaplasma sp., enquanto 0,18% (9/5015) possuíam mórula de ambas as espécies. As fêmeas representaram 57,89% (400/691) dos animais positivos e os machos 42,11% (291/691). 35,02% (242/691) dos animais tinham menos de 1 ano de vida, 54,13% (374/691) tinham entre 1 e 8 anos, e 10,85% (75/691) tinham mais de 8 anos. As fêmeas, com menos de um ano de idade e coinfectadas, apresentaram as alterações mais significativas nos aspectos hematológicos, hematócrito (29%), contagem de hemácias (3 milhões/mm3), contagem de plaquetas (40.000/mm3) e contagem total de leucócitos (16.000 mil/mm3), evidenciando anemia e trombocitopenia. Animais infectados com Anaplasma sp. e Ehrlichia sp., ao mesmo tempo, apresentaram trombocitopenia mais intensa, evidenciada em machos entre 1 e 8 anos (30.000/mm3). As infecções por Anaplasma sp. causaram uma diminuição severa na média da contagem de glóbulos vermelhos, evidenciada em machos (3 milhões/mm3) e fêmeas com menos de 1 ano (3,79 milhões/mm3).
