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 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 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...

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%).
