Application of MALDI-TOF assay for identification and differentiation of mastitis-causing pathogens from milk and non-milk samples
Matrix-assisted laser desorption/ionization time of flight (MALDI-TOF), a culture-dependent assay, is a rapid and reliable method that is able to identify a great variety of isolated bacteria. The MALDI-TOF works by using laser excitation of proteins to create a unique protein spectrum pattern of an unknown microorganism.
Today we had dinner over the sad news of the first case declared of African Swine fever in the South of Belgium. Just a few hours ago we learned that the virus causing this disease, the African Swine Fever virus (ASFv), had been diagnosed in two wild boars. In the absence of new data, everything is speculation. The most plausible explanations for the origin of these infections would be the direct infection of these animals by products contaminated with the virus from infected areas (“again the man is to blame”). Any other explanation would open rather uncomfortable questions to answer.
Glässer disease and nasal microbiota, hot topics of the XIV Swine Production Congress in Córdoba, Argentina
The past 28, 29 and 30 of August, the pig sector of Argentina met in Córdoba (Argentina) to celebrate its XIV Swine Production Congress (in conjunction with the IX congress of swine production of Mercosur and the XX Swine Update Days).
After World War II, several countries in Central and Northern Europe launched campaigns to eradicate bovine tuberculosis (TB). Among them, the United Kingdom, which achieved remarkable success in reducing the incidence and prevalence of bovine TB since the 1950s to the mid-eighties of the last century.
Taenia saginata is a zoonotic parasite that causes taeniosis in people (definitive host) and cysticercosis in cattle (intermediate host). The adult form of the parasite or tapeworm develops in the small intestine of people (taeniasis) while the larval or cysticercus form establishes in the musculature of cattle (cysticercosis).
Viral Comments (40): Biosafety through risk assessments; more flexibility, for sure, but more dispersion?
The release of the new Laboratory Biosafety Manual of the World Health Organization (WHO) is imminent. The last edition dates from 2004 and has become one of the reference texts although it does not provide technical information but rather gives advice and organizes how to approach the world of Biosafety through the classification of microorganisms according to their risks and the corresponding levels of Biosafety of the facilities and their requirements.
On 15th June 2018, Dr. Joaquim Segalés, researcher at IRTA-CReSA and associate professor of UAB, visited the Institute of Animal Husbandry and Veterinary Science of the Shanghai Academy of Agricultural Sciences, SAAS (Shanghai, China). This institute, led by Dr. Huili Liu, is mainly engaged in research and technology developments such as breeding new species and hybridity advantages utilizing pig and poultry, forage feeding, livestock and poultry epidemic disease prevention, and environment protection.
JIACRA-ES report; a One Health approach to associate consumption of antimicrobials and emergence of resistance
Lourdes Migura and Ignacio Badiola, researchers from IRTA-CReSA have actively participated in the elaboration of the JIACRA-ES report, coordinated by the Spanish Agency of Medicines and Medical Devices (AEMPS). This report was presented at the headquarters of Fundación Ramon Areces the 5th of June as part of the National Action Plan to Reduce Antimicrobial Resistance.
Viral comments (39): Infectious Diseases One Health Master at CReSA; a path that starts with a lot of road to walk.
Emerging and re-emerging diseases have fuelled the construction and operation of high number of high biocontainment facilities (or Biosafety level 3) and maximum biocontainment (Biosafety level 4) facilities. Only those centres can manipulate and propagate hazardous and easily transmissible pathogens, even lethal ones, safely. This implies that professionals dedicated to issues of emerging or re-emerging infectious diseases, and in particular also zoonotic diseases, should have not only theoretical knowledge, but also practical, of the facilities in which they will potentially work or that they should manage in the future.
With the theme of “Healthy Pig, Safe Pork, the 25th International Pig Veterinary Society (IPVS) Congress kicked off on June 11, 2018 in Chongqing. More than 5000 delegates attended the conference. While English was the official language of the meeting, the organization provided simultaneous translation to Chinese for all oral presentations. Different aspects of pig production were discussed during 4 days of intense scientific sessions. CReSA participation was centered in the bacterial and viral disease sessions.
