cómo de desplazan los bovinos, hacia y desde las ferias de ganado y como y de dónde llegan a las plantas faenadoras. De esta manera, se podrá avanzar en aumentar la credibilidad de Chile en los mercados internacionales...
Caracterización del riesgo de tuberculosis bovina asociado al movimiento animal en predios bovinos de la provincia de Melipilla
(Universidad de Chile, 2019)
El movimiento de ganado entre predios es uno de los factores más importantes que contribuyen a la difusión de enfermedades infecciosas, como lo es la tuberculosis bovina (TBB). La TBB es enfermedad crónica del ganado bovino, causada por la infección...
The movement of cattle between farms is one of the most important factors that contributes to the spread of infectious diseases, such as bovine tuberculosis (TBB). This is a chronic disease of cattle caused by the infection with Mycobacterium bovis. The origin and destination of livestock movements in Chile are registered by law. This information has a great potential for assessing the risk of disease spreading in these animals. The objective of this study was to describe and characterize the movements of cattle on farms belonging to the province of Melipilla and their implication in the dissemination and transmission of TBB. This is an area with a high prevalence of TBB. Movements of cattle from 2012 to 2017 within the province were described. A total of 283 farms were considered in the study, with 38.5% representing infected herds and 61.5% negative herds. 6103 movements of entry and 8250 movements of exit of cattle were registered, of which the highest percentage of movements were in productive systems corresponding to cattle fattening. The biggest registered movement for supplying farms, was from cattle markets, representing 51,4%; in the case of destination movements, they are mainly to cattle markets and slaughterhouses (66,8%). The highest number of categorized high-risk farms associated to the number of movements, were represented by farms with a sanitary status of infected, in contrast to negative farms, which were mainly categorized in the low-risk categories. These results suggest a direct relationship between the sanitary condition of farms and their movement-associated risk....

Detección y caracterización de campylobacter spp desde heces de bovinos de lechería de predios de la Región Metropolitana
(Universidad de Chile, 2019)
provenientes de bovinos de lecherías de la Región Metropolitana y además caracterizar los perfiles de susceptibilidad a los antimicrobianos de las cepas aisladas.
Este estudio analizó un total de 594 muestras de heces de bovinos en estado productivo, tomadas en...
Campylobacter is an enteric zoonotic bacterium, Gram negative with spiral form, whose main reservoir is birds, but can be present in the intestines of multiple domestic and wild animals. Campylobacter causes a disease called campilobacteriosis which is considered a foodborne illness, which is the main cause of diarrhea in developed countries and second or third in developing countries. The most important foods implicated in outbreaks of campilobacteriosis in the world are chicken meat and milk. In Chile Campylobater is an organism of mandatory surveillance but its derivation to health services is low. Although campilobacteriosis is a self-limiting disease, in some patients is necessary to use antibiotics. Macrolides or fluoroquinolones are mainly used and, as alternative, gentamicin and tetracycline, but the inappropriate use of antibiotics in veterinary medicine and in human medicine can generate the appearance and spread of resistant bacteria, which can make that the treatments are not effective. The objective of this study is to detect Campylobacter jejuni and Campylobacter coli strains, from feces samples from dairy cattle of the Metropolitan Region as well as to characterize the profiles of susceptibility to antimicrobials of the isolated strains. This study analyzed a total of 594 samples of cattle feces in the productive state, taken in 4 dairy farms of the rural area of the Metropolitan Region. These dairies are close to surface water courses where Salmonella spp. strains were previously found to be correlated with outbreaks in humans. In addition, antimicrobial susceptibility tests were performed on isolated strains, it was pointed out the following antibiotics: erythromycin, azithromycin, ciprofloxacin, gentamicin and tetracycline. A total of 20 Campylobacter strains were isolated, by traditional culture, then, all them subjected PCR for species identification, being 50% Campylobacter coli, 45% Campylobacter jejuni and 5% (one strain) that was classified as Campylobacter spp. With respect to sensitivity to antibiotics high levels of resistance to erythromycin were obtained, reaching 60%, for azithromycin 55% and 35% for ciprofloxacin....
