          Abstract

          En una población canina de las áreas rurales del municipio de Montería Córdoba (Colombia), se determinó la seroprevalencia de leptospirosis, para lo cual se tomaron muestras de sangre en 200 caninos procedentes de los 28 corregimientos; estas se procesaron en el laboratorio del Instituto Colombiano Agropecuario (ICA) mediante técnica de microaglutinación lisis (MAT). Se determinó una seroprevalencia del 12 %, distribuyéndose la seropositividad entre los serovares: canicola 7 %, icterohaemorragiae y grippotyphosa 2 %, bratislava 1 %, no hubo seroreactividad para los servoraes hardjo y pomona. Sólo para el serovar canicola, se obtuvo un titulo de 1: 200. Se demostró, que los caninos de las áreas rurales del municipio de Montería están o han estado en contacto con cepas de Leptospira spp; constituyendo en un factor de riesgo para la diseminación del agente etiológico.

          Translated abstract

          The seroprevalence of leptospirosis was determined in a canine population in the rural area of the municipality of Monteria, Cordoba (Colombia). Blood samples were taken in 200 dogs of 28 townships, which were processed in the laboratory of the Instituto Colombiano Agropecuario (ICA) by microscopic agglutination technique (MAT). A seroprevalence of 12 % was determined and the seropositivity distributed among the serovars: canicola 7 %, icterohaemorrhagiae and grippotyphosa 2 %, bratislava 1 % and no seroreactivity for serogroups hardjo and pomona. A title greater than 1: 20 was not found for any of the strains. It was demonstrated that the canines of the rural municipality of Monteria are or have been in contact with strains of Leptospira spp, which constitutes a risk factor for the spread of the etiologic agent.

              Seroepidemiology of canine leptospirosis on the island of Barbados.

              Previous surveillance in Barbados documented the absence of infection with Leptospira serogroup Canicola in dogs. The aim of this study was to survey the current state of canine leptospirosis in Barbados, 10 years after the last survey. Sera from 78 unwanted dogs scheduled for euthanasia and 61 dogs suspected of having acute leptospirosis were tested by microscopic agglutination (MAT) and by an ELISA method adapted for canine IgM and IgG antibodies. The seroprevalence in unwanted dogs was 62% (48/78), at an MAT titre of > or = 100. The majority of animals had low titres, suggestive of previous infection. Serogroup Autumnalis was the most common reactor (45%), followed by serogroups Icterohaemorrhagiae and Australis (each 16%) and Pomona (13%). Serogroup Ballum was uncommon in this group. The seroprevalence determined by MAT in acutely-ill dogs was 75% (46/61). The most common predominant serogroup was Icterohaemorrhagiae (36%) followed by serogroup Australis (13%), while serogroups Autumnalis and Ballum were also of little significance. Paired specimens were available from eight acutely-ill dogs. One animal was seronegative while five dogs showed evidence of seroconversion. An IgM-ELISA titre of > or = 320 was used to confirm current infection in eight of these nine animals. Previous studies in Barbados showed a higher prevalence of serogroup Icterohaemorrhagiae than of Autumnalis, but the relative frequency of these two serogroups may be changing. The high seroprevalence in dogs is of public health concern because the close contact between dogs and man may provide the link between a reservoir in the environment and susceptible humans.
