Objectives. Determine the presence and the type of endoparasites with zoonotic potential in swine and human of two technified and two semi-technified farms in the department of Cundinamarca, Colombia. Materials and methods. Three serial samplings of feces were taken in a pen row within intervals of 15 days, in two technified and two semi-technified farms in different age groups distributed as follows: pregnant-sows, nursing-females, boars, weaners, suckling-piglets, and growing-pig. By means of informed consent thirty-three people agreed to enter the study. Thirty-three samples from men and women of different ages were received. The pool and individual samples of fecal were evaluated by direct analysis, qualitative flotation and sedimentation techniques and modified Ziehl- Neelsen stain. Results. For the porcine population, on the average, the results obtained from both technified farms showed that Balantidium coli (42%), Endolimax nana (21.9%) and Iodamoeba bütschlii (7.8%) were the most common parasites. In semi-technified farms they were: Entamoeba coli (40%), Endolimax nana (35%), Iodamoeba bütschlii (25%) and Balantidium coli (5%). By means of the test chi2 it is possible to conclude that there is a significant difference between the parasites species and the type of farm. The results obtained in human showed the presence of parasites as: E. coli (42.2%), Entamoeba hystolitica/dispar (12.1%), E. nana (9.1%), B. coli (9.1%), I. bütschlii (3.0%) and Blastocystis hominis (3.0%). Conclusions. The presence of parasites such as Balantidium coli, Endolimax nana, Iodamoeba bütschlii and Entamoeba coli in swine and human suggests a possible rotation of parasitic species between hosts.

To determine Salmonella spp. prevalence/seroprevalence, antimicrobial resistance patterns and risk factor identification associated with its presence in Colombian swine farms. 504 samples (Faeces, swabs and environment samples) were obtained from 21 farms distributed in four geographical regions in Colombia. Salmonella spp. microbiological and molecular detection were determined by two Salmonella spp. MDS3M™ and MALDI-TOF MS assays, respectively. In addition, for serological evaluation 231 serum samples were analyzed employing ELISA Salmonella Pigtype®-Salmonella Ab (QUIAGEN®). Additionally, 41 isolates were tested for antimicrobial susceptibility using broth microdilution technique (Panel B1016-180 Beckman Coulter NC72®) and verified with WHONET 2016 software. Risk factors were assessed from a survey and analyzed for statistical significance by U Mann-Whitney test. An 8.9% prevalence (n=45) and 38.1% (n=88) seroprevalence were determined. All isolates presented 100% antimicrobial susceptibility against amikacin. However, resistance against penicillin, tetracycline, cefuroxime and trimethoprim/sulfamethoxazole was present in more than 50% of evaluated strains. Risk factors associated with Salmonella spp. presence were surface water use, rough-surfaced on floors, presence of hoppers as feeders and worker’s boots. Bacteria were present in animals and environmental samples from evaluated farms. Animal contact and/or exposure with the microorganism were also evident in obtained serological response. Bacteria presence depended on management practices and infrastructure, likewise antibiotic use, supplemented in the diet may have induced an increase in Salmonella spp. antimicrobial resistance.

To identify and describe the epidemiological status of human leptospirosis or Weil's disease, we searched scientific publications and reports issued by health control authorities from 2006 to 2013. Information extraction was done independently and the methodological quality of the articles was evaluated using a checklist created for that purpose. The country with the highest incidence of human leptospirosis was Trinidad & Tobago (22 cases per 100,000 people) and the highest percentage of cases occurred in Guyana (60%). In Colombia, the department with the highest percentage of cases was Antioquia (85.7%) and the highest incidence was in Cordoba (67.9%). Contact with animals is possibly the highest risk factor; its diagnosis is commonly accomplished using a microscopic agglutination test. The analyzed data presented various epidemiological aspects, making it difficult to merge the information. Only in some countries is the academic and governmental interest and awareness evident in the area of public health.

Objective. To determine the correlation between microbiological culture and otic cytology for diagnoses of external otitis by Malassezia in dogs. Materials and methods. 158 ear swabs of dogs with clinical diagnosis of external otitis were analyzed by cytology, mycological culture and metabolic tests. Results. Were obtained a positive results by cytology of 62% and 75.3% by culture. The 31.1% of isolates were identified as M. pachydermatis, 12.6% as M. furfur and 56.3% were classified as Malassezia spp., because was not possible to define the species. We found a positive concordance between cytology and culture for Malassezia spp., of 0.76 with a kappa index of 0.448 (95% CI 0.30 to 0.60) which represents a moderate strength of concordance between the two techniques, without regard the identified species. Conclusions. The use of a diagnostic test is not enough to establish the participation of Malassezia spp., as a causal disease agent.

Determinar la concordancia entre el cultivo microbiológico y la citología ótica para el diagnóstico de otitis externa causada por Malassezia spp. en caninos. Materiales y métodos. Se analizaron 158 muestras de hisopados de caninos con diagnóstico clínico de otitis externa, todas las muestras fueron analizadas mediante citología, cultivo micológico y pruebas metabólicas. Resultados. Se obtuvo una positividad mediante citología del 62% y por cultivo del 75.3%. El 31.1% de los aislamientos fueron identificados como M. pachydermatis, el 12.6% como M. furfur y un 56.3% se clasificó como Malassezia spp., dado que bioquímicamente no fue posible hallar su especie. Se determinó una concordancia observada entre técnicas positivas para Malassezia spp. de 0.76 con índice Kappa de 0.448 IC 95% (0.30 -0.60) lo que representa una fuerza de concordancia moderada entre las dos técnicas, sin tener en cuenta la especie identificada. Conclusiones. El uso de una prueba diagnóstica no es suficiente para establecer la participación de Malassezia pachydermatis como agente causal de enfermedad.Palabras clave: Canis familiaris, técnicas diagnósticas, Malassezia, otitis externa (Fuente: CAB).
