Perfil hematológico del burro criollo (Equus asinus) colombiano

The diagnosis of diseases in animals depends to a large extent on clinical examinations and laboratory results, in which biological variations are reflected. The hematological values are very important for the evaluation of the normal physiological state of an animal. However, very few works have been carried out in this respect on creole asses. The objective of this investigation was to determine the mean values of a hemogram for creoles donkeys of the Colombian lowland. A cross - sectional descriptive study was performed with a non - probabilistic sample for convenience. Samples of 85 male donkeys between 4 and 15 years old were clinically healthy and fed with Brachiaria humidicula pastures. These parameters were obtained by means of a hematological analyzer (ABX Micros ESV 60). The values obtained were: leukocytes 7.6±1.6 x103/mm3, lymphocytes 39.69±10.87%, monocytes 5.89±1.63%, granulocytes 54.41±10.75%, eosinophils 7.08±2.77%, erythrocytes 4.48±0.85 x106/mm3, hemoglobin 8.62±1.3 g/dL, hematocrit 30.24 ± 5.1%, mean corpuscular volume 67.71±5.91 ?m3, mean corpuscular hemoglobin 19.45±1.94 pg, mean corpuscular hemoglobin concentration 28.48±1.36 g/dL and platelets 354.20±136.24 x103/mm3. The results confirm that there are differences between the values in most hematological parameters of creole donkeys compared to those of other breeds and horses. These results may be useful in the veterinary clinical routine for the diagnosis, monitoring and control of diseases.El diagnóstico de las enfermedades en los animales, depende en gran medida de los exámenes clínicos y resultados de laboratorio, en los cuales se reflejan variaciones biológicas. Los valores hematológicos son muy importantes para la evaluación del estado fisiológico normal de un animal. Sin embargo, son muy pocos los trabajos que se han llevado a cabo en este aspecto en asnos criollos. El objetivo de esta investigación fue determinar los valores medios de un hemograma para burros criollos del tópico bajo colombiano. Se realizó un estudio descriptivo de corte transversal con muestro no probabilístico por conveniencia. Se tomaron muestras de 85 burros machos entre 4 y 15 años clínicamente sanos y alimentados con pasturas de Brachiaria humidicula. Estos parámetros se obtuvieron por medio de un analizador hematológico (ABX Micros ESV 60). Los valores obtenidos fueron: leucocitos 7,6±1,6 x103/mm3, linfocitos 39,69±10,87%, monocitos 5,89±1,63%, granulocitos 54,41±10,75%, eosinófilos 7,08±2,77%, eritrocitos 4,48±0,85 x106/mm3, hemoglobina 8,62±1,3 g/dL, hematocrito 30,24±5,1%, volumen corpuscular medio 67,71±5,91 µm3, hemoglobina corpuscular media 19.45±1.94 pg, concentración de hemoglobina corpuscular media 28,48±1,36 g/dL y plaquetas 354,20±136,24 x103/mm3. Los resultados confirman que existen diferencias entre los valores en la mayoría de los parámetros hematológicos de burros criollos comparados con los de otras razas y equinos. Estos resultados pueden ser útiles en la rutina clínica veterinaria para el diagnóstico, seguimiento y control de enfermedades

Psitacosis y salmonelosis: zoonosis que involucran a las aves

Zoonosis refers to infectious animal diseases that can be transmitted to humans. Infectious agents can be protozoa, fungi, bacteria, chlamydia, viruses or prions. Birds represent a high risk of getting a disease like this, not only by being in contact with them, but by eating foods derived from them. Two major zoonosis that involve birds are psittacosis and salmonellosis. Psittacosis is caused by Chlamydophila psittaci. It can cause anything from mild pneumonia to death of the animal; It is transmitted to humans through inhalation of the organism, producing a clinical picture characterized by pneumonia and systemic manifestations. The populations most at risk of acquiring this zoonosis are veterinarians, breeders of birds and every person in contact with infected birds. Salmonellosis is caused by a large number of species of Salmonella. Transmission occurs by eating contaminated with bacteria such as egg and meat foods. Diarrhea, fever and severe stomach cramps are common symptoms in the case of salmonellosis. The aim of this article is to review the general aspects of the disease and the process of transmission to humans. Zoonosis se refiere a enfermedades infecciosas de animales que se pueden transmitir a los humanos. Los agentes infecciosos pueden ser protozoarios, hongos, bacterias, clamidias, virus o priones. Las aves representan un riesgo alto de adquirir una enfermedad de este tipo, no solamente por estar en contacto con ellas, sino por consumir alimentos derivados de las mismas. Dos las zoonosis más importantes que involucran a la aves son la psitacosis y salmonelosis. La psitacosis es producida por Chlamydophila psittaci. Puede causar desde una leve neumonía hasta la muerte del animal; se transmite al humano a través de la inhalación del microorganismo, produciendo un cuadro clínico caracterizado por neumonía y manifestaciones generales. Las poblaciones con mayor riesgo de adquirir esta zoonosis son veterinarios, criadores de aves y toda persona en contacto con aves infectadas. La salmonelosis es causada por una gran cantidad de especies de Salmonella. La transmisión se da por el consumo de alimentos contaminados con la bacteria tales como el huevo y la carne. La diarrea, la fiebre y los calambres estomacales severos son síntomas comunes, en el caso de salmonelosis. El objetivo de este artículo se centra en revisar los aspectos generales de las enfermedades y el proceso de transmisión a los humanos

The type of study was cross-sectional descriptive. The study was conducted on 47 farms between August and November 2015. coprological samples were collected and flotation technique was used, examined 144 samples of the 144 samples examined 136 (94.44%) were positive least for some kind of parasite. The frequencies were found Trichostrongylus spp. 91.67% Strongylus spp. 68.06%, 66.67% westeri Strongyloides, Parascaris equorum 9.72%, 5.56% and Anoplocephala perfoliata Eimeria spp. 2.78%. It was concluded that there is a high presence of nematodes compared with tapeworms and protozoa found in the asses of Córdoba department, Colombia.El presente estudio fue diseñado con el objetivo de determinar la frecuencia de parásitos gastrointestinales en burros criollos (Equus africanus asinus) del departamento de Córdoba, Colombia. El tipo de estudio fue descriptivo transversal. El estudio se llevó a cabo en 47 predios entre los meses de agosto y noviembre de 2015. Se recolectaron muestras coprológicas y se empleó la técnica de flotación, examinándose 144 muestras, De las 144 muestras examinadas 136 (94,44%) resultaron positivas al menos para algún género de parásito. Las frecuencias encontradas fueron de Trichostrongylus spp. 91,67%, Strongylus spp. 68.06%, Strongyloides westeri 66,67%, Parascaris equorum 9,72%, Anoplocephala perfoliata 5,56% y Eimeria spp. 2,78%. Se pudo concluir que existe una elevada presencia de nematodos en comparación con los cestodos y protozoarios, encontrados en los asnos del departamento de Córdoba, Colombia

Resistencia in vitro de la garrapata equina (Dermacentor nitens) en el departamento de Córdoba, Colombia

Determine the resistance of the tick Dermacentor nitens to metrifonate (Neguvon®, Bayer©, Germany), cypermethrin (Ganabaño®, Novartis©, USA), and amitraz (Triatox®, Schering Plough ©, USA). A non-probabilistic convenience experimental study, five plots where teleogines 120 engorged D. nitens were collected, the teleogines were subjected to immersion test according to Drummond. It was found that the treatment was less chemoresistance produced amitraz 97% effective, followed by 93% cypermethrin and 53% respectively metrifonate. An oviposition evaluation, it was found that amitraz is the most effective 23%, cypermethrin 18% and then metrifonate 1%. The percentage hatching assessment was higher for metrifonate 18.97%, cypermethrin 4.70% and Amitraz 1.68% respectively. It is concluded that amitraz is the most effective acaricide in vitro not only affect adults but to eliminate the cycle of D. nitens, but its use in practice is unlikely in vivo by toxic effects in horses. Among the products used in horses, cypermethrin is the drug of choice.Determinar la resistencia de la garrapata Dermacentor nitens a metrifonato (Neguvon®, Bayer©, Alemania), cipermetrina (Ganabaño®, Novartis©, USA), y amitraz (Triatox®, Schering Plough©, USA). Un estudio experimental no probabilístico por conveniencia, de cinco predios, donde se recolectaron 120 teleogínas ingurgitadas de D. nitens, las teleogínas fueron sometidas a inmersión según prueba de Drummond. Se encontró que el tratamiento que menos quimioresistencia produjo fue amitraz con 97% de efectividad, seguido por cipermetrina con 93% y metrifonato con 53% respectivamente. A la evaluación de la oviposición, se encontró que amitraz es el de mayor efectividad 23%, luego cipermetrina 18% y metrifonato con 1%. La evaluación porcentual de eclosión fue mayor para el metrifonato con 18,97%, cipermetrina con 4,70% y amitraz con 1,68% respectivamente. Se concluye que amitraz es el acaricida más efectivo in vitro no solo para eliminar adultos sino afectar el ciclo de D. nitens, pero su uso en la práctica in vivo es improbable por los efectos tóxicos en équidos. Entre los productos utilizables en los equinos, la cipermetrina es el fármaco de elección

Determinación coprológica de la parasitofauna en cerdos criollos (Sus scrofa domestica) en el departamento de Córdoba, Colombia

  The objective of the research was to determine the parasitic fauna in Colombian creole pigs reared outdoors in the department of Cordoba, Colombia. The study was conducted on 62 farms, examining a total of 166 samples using the technique of flotation and McMaster. The found results demonstrate the presence of 10 genera of nematodes, one of protozoa and one of acanthocephalan. It is to emphasize the absence of tapeworms and flukes in the study. Regarding the age of the animals, increased frequency of gastrointestinal parasites in young animals relative to adult animals was found. These infections by coccidia and nematodes can be considered as a problem of medical and economic importance should be subject to greater attention for its control since they act as constraints on production systems, being associated to losses and delays in production and profitability herds.  El objetivo de la investigación fue determinar la fauna parasitaria en Cerdos Criollos Colombianos criados al aire libre en el departamento de Córdoba, Colombia. El estudio se llevó a cabo en 62 predios, examinando un total de 166 muestras haciendo uso de la técnica de Flotación. Los resultados hallados demuestran la presencia de 10 géneros de nematodos, uno de protozoos y uno de acantocéfalo. Se ha de destacar la ausencia de cestodos y trematodos en el estudio. En relación a la edad de los animales, se encontró mayor frecuencia de parásitos gastrointestinales en animales jóvenes en relación con los animales adultos. Estas infecciones por coccidias y nematodos pueden considerarse como un problema de importancia médica y económica que debe ser objeto de mayor atención para su control ya que actúan como limitantes en los sistemas de producción, siendo asociadas a pérdidas y retrasos en la producción y rentabilidad de las piaras
