In Colombia, the departments of Cundinamarca, Huila and Tolima, among others, represent 19.16% of the total domestic production of pig farms. Gastrointestinal parasites (PGI) limit the productive potential of infected animals, affecting parameters such as average daily gain and food conversion ratio. The aim of the study was to determinate the prevalence of PGI with a zoonotic potential in backyard farms and semi-technical production. Farmyard pigs were sampled in three semi-technified farms with full production cycle (breeding, fattening and lift) in the municipalities of Vega, Chia, Tibirita and in four backyard pig farms (fattening) in the towns of Chía and Santandersito. The farms were chosen for convenience. Three samplings were performed serially at intervals of 15 days and analyzed with a total of 119 samples, 94 farms and 25 semi-technified backyard farms. Stool samples in "pool...

Malassezia and Candida yeasts are considered part of the normal skin and mucosal microbiota in humans and other animals; however, there have been few studies on the pig’s ear canal microbiota. The aim of this study was to identify the yeast microbiota isolated from swabs of porcine ear canal. Primary isolation from 25 samples (16 and 9 pigs with and without brownish serous secretion) in Dixon and Sabouraud medium. Macroscopic and microscopic morphological features were described. Besides, biochemical, physiological and molecular tests were performed to identify the isolated yeasts. Fifty-five isolates were recovered and the molecular identification showed the presence of M. sympodialis (42.8%), M. slooffiae (28.6%), M. furfur (18.4%) and M. pachydermatis (8.2%).

The aim of this study was to determine the presence of antibodies against pathogens of pigs that represent public health risk due to their zoonotic potential (Salmonella spp, Leptospira interrogans, Yersinia spp, Trichinella spp and Toxoplasma gondii) in porcine sera obtained in four semi-technified pig farms from Cundinamarca, Colombia. A total of 89 blood samples were collected and analyzed using the ELISA diagnostic kits Pigtype®- Salmonella Ab, Pigtype®-Yopscreen, Pigtype®-Toxoplasma Ab and Pigtype®-Trichinella (QuiaGen®) The detection of antibodies against Leptospira spp was carried out by the microagglutination lysis test (MAT). Antibodies against Salmonella spp was observed in 40% of the samples, while for Yersinia spp and Toxoplasma gondii was in 18 and 1.1% respectively. At least one of the 13 serovars of Leptospira interrogans was detected in all four farms and none of the...

El objetivo del presente trabajo fue determinar la presencia de anticuerpos frente a rotavirus en sueros de porcinos obtenidos de granjas semitecnificadas de Cundinamarca, Colombia. Se procesaron 170 muestras de varios grupos etarios, utilizando el estuche de ELISA para diagnóstico Ingezim Rotavirus Porcino (Ingenasa®). Se detectó la presencia de anticuerpos frente a Rotavirus en el 78.82% de las muestras. Se concluye que los animales pudieron haber estado en contacto con el virus en algún momento de su ciclo productivo, lo que sugiere la necesidad de mejoras en el control y prevención de la infección.

Colombian pork production has increased over the years; however, given the socioeconomic conditions of the country, people who are related to these farms can acquire zoonotic pathogens and develop disease. To identify the risk factors associated with the transmission of zoonotic diseases, a review of the literature was carried out following the steps of a «scoping review»; by searching for scientific articles in the MEDLINE, Web of Science and SciELO databases, applying DeCS terms. In total, 31 documents met the inclusion criteria and were analyzed. For the transmission of zoonotic diseases from pig farming to humans, the risk factors described were: poor higiene habits of workers, inadequate handling of animal and human excreta, and the presence of pests on farms such as rodents, among others; however, the information related to this type of pathology is scarce, so it is necessary to ...

The aim of this study was to determine the presence of antibodies against rotavirus in pig sera obtained from semi-technical farms in Cundinamarca, Colombia. For this, 170 samples from various age groups were processed, using the Porcine Ingezim Rotavirus (Ingenasa®) diagnostic ELISA kit. The presence of antibodies against Rotavirus was detected in 78.82% of the samples. It is concluded that the animals may have been in contact with the virus at some point in their production cycle, which suggests the need for improvements in the control and prevention of infection.

The ectoparasites significantly affect the health status of the animals due to their toxic and allergic effects that cause a detriment in their welfare and additionally may have a negative effect on feed conversion rates in farm animals. Ectoparasites can affect animals of all species and ages, being the young animals the most susceptible. The importance of a proper diagnosis of these health problems is given not only by the discomfort they generate in their hosts, but by the fact that they can transmit other pathogens. The aim of this paper was to describe some morphological characteristics of specific ectoparasites that have veterinary importance, especially under the prevailing environmental conditions in Colombia.

Los ectoparásitos afectan de manera importante el estado sanitario de los animales debido a que sus efectos exfoliatrices, tóxicos y alérgicos causan un detrimento en su bienestar y, adicionalmente, pueden tener un efecto negativo en los índices de conversión alimenticia en animales de producción. Las ectoparasitosis pueden afectar animales de todas las especies y edades; sin embargo, los jóvenes son los más susceptibles. La importancia de un adecuado diagnóstico de estos problemas sanitarios está dada no solo por la incomodidad que generan en sus hospederos, sino por la posibilidad que tienen de transmitir otros agentes patógenos. El objetivo del presente trabajo fue presentar imágenes donde se describen algunas características morfológicas de determinados ectoparásitos de interés en Medicina Veterinaria, especialmente bajo las condiciones de Colombia.

In order to determine the prevalence of Toxocara canis Werner, 1782, Ancylostoma caninum Ercolani, 1859 and Isospora canis Nemeseri, 1959 in street dogs at the Bogota Zoonosis Animal Shelter, seventy pooled fecal samples from cage floors were collected. Each pooled sample corresponded to one of 11 localities since the dogs were caged according to locality. Three serial samplings were performed. Each pooled sample was evaluated macroscopically and microscopically using qualitative and quantitative parasitological techniques to determine the presence of helminth eggs or oocysts. A total of 88,57% (n= 62) of the samples were parasite positive: 52,9% were positive for A. caninum; 7,1% for T. canis; 24,3% showed mixed infections of A. caninum and T. canis, 1,43% were positive for A. caninum, T. canis and I. canis and 2,9% were infected by A. caninum and I. canis. The pooled fecal samples from...

The aim of this study was to determine the presence of fungal pathogens from dermatological lesions of large and small animal species in veterinary clinics and animal shelters in Bogotá, Colombia. From a total of 30 canines, 15 felines and 2 equines, skin scraping samples (31) and otic (26) and skin (44) swabs were obtained, which were analysed by direct examination, culture and identification at the species level. Microsporum canis and Malassezia spp were mainly identified. According to the animal species, M. canis (21.4%) predominated in felines and Malassezia pachydermatis (32.1%) in canines. According to the type of sample, a higher frequency of M. canis was detected in skin scraping (21.4%) and Malassezia spp in ear swabbing (21.4%).
