“…However, the same study (3) reported that dogs had never been evaluated as carriers of Leptospira in Egypt, and the observed seroprevalence in that study was 12%, which was similar to the seroprevalence reported in Italy (20) and Thailand (21) but much lower than that reported in Germany (22) , Mexico (23) and the USA (24) . The same study found a high seroprevalence of leptospires in cows (44%).…”

Introduction: Leptospirosis is a re-emerging zoonotic disease of humans and animals worldwide. The disease is caused by pathogenic species of the genus Leptospira. These organisms are maintained in nature via chronic renal infection of carrier animals, which excrete the organisms in their urine. Humans become infected through direct or indirect exposure to infected animals and their urine or through contact with contaminated water and soil. This study was conducted to investigate Leptospira infections as a re-emerging zoonosis that has been neglected in Egypt. Methods: Samples from 1,250 animals (270 rats, 168 dogs, 625 cows, 26 buffaloes, 99 sheep, 14 horses, 26 donkeys and 22 camels), 175 human contacts and 45 water sources were collected from different governorates in Egypt. The samples were collected from different body sites and prepared for culture, PCR and the microscopic agglutination test (MAT). Results: The isolation rates of Leptospira serovars were 6.9%, 11.3% and 1.1% for rats, dogs and cows, respectively, whereas the PCR results revealed respective detection rates of 24%, 11.3% and 1.1% for rats, dogs and cows. Neither the other examined animal species nor humans yielded positive results via these two techniques. Only six Leptospira serovars (Icterohaemorrhagiae, Pomona, Canicola, Grippotyphosa, Celledoni and Pyrogenes) could be isolated from rats, dogs and cows. Moreover, the seroprevalence of leptospiral antibodies among the examined humans determined using MAT was 49.7%. Conclusions: The obtained results revealed that rats, dogs and cows were the most important animal reservoirs for leptospirosis in Egypt, and the high seroprevalence among human contacts highlights the public health implications of this neglected zoonosis.

[28][29][30][31][32] Such discrepancies may be because of the relatively limited number of animals used or differences in climatic or geographical conditions.…”

Abstract. A survey of 179 animals (black rats, dogs, sheep, buffaloes, cattle, donkeys, weasels, and cats) for Leptospira infection was conducted in Mahalla City (Lower Egypt). Blood, urine, and kidney were collected and tested by culture, microscopic agglutination test (MAT), and/or polymerase chain reaction (PCR). Among rats, 26% were positive by PCR, including 7% that were also positive by culture for L. interrogans serovars Grippotyphosa, Pyrogenes, and Icterohaemorrhagiae. L. borpetersenii serovar Polonica was isolated for the first time in Egypt in three rats. MAT titers ≥ 1:800 were observed in 11% of rats and 12% of dogs. L. interrogans serovar Grippotyphosa was detected in one cat. Sheep and donkeys were negative for leptospirosis by all methods. Buffaloes and cattle were seropositive in 20% and 44% of animals, respectively. Data indicate that several pathogenic serovars are circulating in the animals, which may pose exposure risks and account for high rates of acute febrile illness.

“…La infección en humanos se presenta por contacto directo de las mucosas con orina de los animales infectados o indirectamente a través de agua o suelos contaminados (7)(8)(9). Los caninos se comportan como importantes reservorios de Leptospira sp y fuentes de infección para el hombre, especialmente en población general, por su estrecho contacto con el hombre en ambientes de riesgo no ocupacional (8,10).…”

Prevalencia de anticuerpos contra Leptospira en población urbana humana y canina del Departamento del TolimaRev. salud pública. 12 (2): [268][269][270][271][272][273][274][275] 2010 The prevalence of antibodies against Leptospira in urban human and canine populations from the Tolima Department RESUMENObjetivo Determinar la seroprevalencia de anticuerpos contra Leptospira sp. y los serovares dominantes, en población urbana humana y canina de tres municipios del departamento del Tolima, Colombia. Materiales y Métodos Se realizó un estudio epidemiológico trasversal con selección de sujetos por conveniencia en 62 barrios. Se obtuvieron muestras de 850 personas.y 850 caninos durante los meses de junio, julio y agosto de 2007, las cuales fueron procesadas utilizando la prueba de microaglutinación (MAT). En la prueba se incluyeron 5 serovares: Hardjo, Pomona, Grippotyphosa, Canicola, Icterohaemorrhagiae y Bratislava. La prueba se interpretó como positiva por la presencia de una aglutinación 50 % de las leptospiras con uno o más serovares, en una dilución del suero 100 para las dos especies. Resultados Se encontró evidencia de infección en el 6 % de la población humana y en el 21,4 % de los caninos, con al menos uno de los serovares. La mayor reactividad fue para los serovares Pomona y Grippotyphosa para humanos y caninos. Se presentaron coaglutinaciones en el 13,7 % de los sueros humanos y en el 4,4 % de los caninos. Fue evidente la disminución de la frecuencia de aglutinación de los serovares Canicola e Icterohaemorrhagiae en los perros. Conclusiones Se observa un cambio en el patrón de presentación de la leptospirosis en poblaciones urbanas, siendo necesario fortalecer la vigilancia epidemiológica activa y pasiva, la implementación de pruebas rutinarias de diagnóstico y medidas de prevención específica en los reservorios animales.Palabras Clave: Estudios seroepidemiológicos, leptospirosis, factores de riesgo (fuente: DeCS, BIREME).
