Otitis bovina por Rhabditis bovis en C贸rdoba, Colombia. Reporte de dos casos
Se reportan dos casos de bovinos de la raza Gyr puros, atendidos en el servicio ambulatorio de la cl铆nica medico-quir煤rgica de grandes animales de la Facultad de Medicina Veterinaria y Zootecnia de la Universidad de C贸rdoba, Colombia. Los animales presentaron al examen f铆sico signos de otitis cl铆nica en ambos lados, con otorrea, olor f茅tido, inflamaci贸n con cierto grado de estenosis del conducto auditivo, inclinaci贸n de la cabeza, prurito intenso y rascado excesivo de las orejas. Se realiz贸 inspecci贸n directa y colecta de material del conducto auditivo externo, y se observ贸 en forma directa el movimiento de los par谩sitos en el cerumen, posteriormente confirmado por observaci贸n microscopio-estereosc贸pico, en el laboratorio de parasitolog铆a de la Facultad de Medicina Veterinaria de la Universidad de C贸rdoba, en el cual se revel贸 la presencia de larvas y adultos de nem谩todos del g茅nero Rhabditis bovis. Es el primer reporte de esta enfermedad en bovinos de la raza Gyr en el departamento de C贸rdoba y Colombia
Genome evolution in the genus Caenorhabditis
The free-living nematode Caenorhabditis elegans is an important laboratory
model organism that has been fundamental to the understanding of metazoan
biology. However, until recently, C. elegans has largely been studied in
isolation, with its evolutionary history poorly understood. Recent progress in
our understanding of natural ecology of C. elegans has led to the discovery of
many new species from the genus Caenorhabditis, most of which are in
laboratory culture. In 2014, an international collaboration was launched
which aimed to sequence the genomes of all species currently in culture. In
this thesis, I present draft genomes for 38 Caenorhabditis species generated
using both short- and long-read technology. I also present the genome of C.
bovis, a species which appears to live parasitically in the ears of cattle in
Eastern Africa. I exploited these and other genome sequences to perform the
most comprehensive reconstruction of the Caenorhabditis phylogeny to date.
Analysing genome size and content within the context of this phylogeny, I
reveal extensive variation in genome size that is driven by changes in gene
number and repetitive content. The work presented in this thesis represents a
substantial contribution to the understanding of genome evolution in
Caenorhabditis. Moreover, these data will become fundamental in our
attempts to understand the evolutionary origins of this important model
organism
Otitis bovina por Rhabditis bovis en C贸rdoba, Colombia. Reporte de dos casos
Two cases of pure Gyr bred bovines, treated at the outpatient medical-surgical clinic for large animals of the Faculty of Veterinary Medicine and Animal Husbandry, at the University of Cordoba, Colombia are reported. During the physical examination, the animals showed signs of clinical otitis with otorrhea, fetid odor, swelling with some degree of stenosis of the ear canal, head inclination, intense itching and excessive scratching of both ears. Direct inspection was performed and a collection of material from the outer ear canal was taken, the movement of parasites in the wax was directly observed, and later confirmed by observation under a stereoscopic microscope in the Parasitology laboratory of the Faculty of Veterinary Medicine at the University of Cordoba, which revealed the presence of nematode larvae and adults of the genus Rhabditis bovis. This is the first report of this disease in Gyr cattle in the department of Cordoba and in Colombia.Se reportan dos casos de bovinos de la raza Gyr puros, atendidos en el servicio ambulatorio de la cl铆nica medico-quir煤rgica de grandes animales de la Facultad de Medicina Veterinaria y Zootecnia de la Universidad de C贸rdoba, Colombia.
