Association between teat skin colonization and intramammary infection with Staphylococcus aureus and Streptococcus agalactiae in herds with automatic milking systems
(Elsevier, 2018-11-08)
The objective of this study was to investigate the association between teat skin colonization and intramammary infection (IMI) with Staphylococcus aureus or Streptococcus agalactiae at the quarter level ...
Culex flavivirus infection in a Culex pipiens mosquito colony and its effects on vector competence for Rift Valley fever phlebovirus
(BioMed Central, 2018-05-23)
Background
Rift Valley fever is a mosquito-borne zoonotic disease that affects domestic ruminants and humans. Culex flavivirus is an insect-specific flavivirus that naturally exists in field mosquito ...
Recombinant PrPSc shares structural features with brain-derived PrPSc: Insights from limited proteolysis
(Public Library of Science, 2018-01-31)
Very solid evidence suggests that the core of full length PrPSc is a 4-rung β-solenoid, and that individual PrPSc subunits stack to form amyloid fibers. We recently used limited proteolysis to map the ...
Porcine circovirus 2 (PCV-2) genetic variability under natural infection scenario reveals a complex network of viral quasispecies
(Nature Research, 2018-10-19)
Porcine circovirus 2 (PCV-2) is a virus characterized by a high evolutionary rate, promoting the potential
emergence of diferent genotypes and strains. Despite the likely relevance in the emergence of ...
Analysis of the genetic diversity and mRNA expression level in porcine reproductive and respiratory syndrome virus vaccinated pigs that developed short or long viremias after challenge
(BioMed Central, 2018-02-15)
Porcine reproductive and respiratory syndrome virus (PRRSv) infection alters the host’s cellular and humoral immune
response. Immunity against PRRSv is multigenic and vary between individuals. The aim ...
Understanding the legal trade of cattle and camels and the derived risk of Rift Valley Fever introduction into and transmission within Egypt
(Public Library of Science, 2018-01-19)
Rift Valley Fever (RVF) is a mosquito-borne zoonosis, which may cause significant losses for the livestock sector and have serious public health implications. Egypt has been repeatedly affected by RVF ...
Limited Interactions between Streptococcus Suis and Haemophilus Parasuis in In Vitro Co-Infection Studies
(MDPI, 2018-01-06)
Streptococcus suis and Haemophilus parasuis are normal inhabitants of the porcine upper
respiratory tract but are also among the most frequent causes of disease in weaned piglets worldwide,
causing ...
Viral and bacterial investigations on the aetiology of recurrent pig neonatal diarrhoea cases in Spain
(BioMed Central, 2018-04-05)
Neonatal diarrhoea represents a major disease problem in the early stages of animal production, increasing significantly pre-weaning mortality and piglets weaned below the target weight. Enteric diseases ...
Toxoplasma gondii infection in wild mustelids and cats across an urban-rural gradient
(Public Library of Science, 2018-06-20)
The increase in human population and domestic pets, such as cats, are generating important consequences in terms of habitat loss and pathogen pollution of coastal ecosystems with potential to generate ...
Assessment of the in vitro growing dynamics and kinetics of the non-pathogenic J and pathogenic 11 and 232 Mycoplasma hyopneumoniae strains
(BioMed Central, 2018-05-25)
Information on the in vitro growth of pathogenic and non-pathogenic Mycoplasma hyopneumoniae (M. hyopneumoniae) strains is scarce and controversial. Despite its limitations, the colour changing units ...
