Epidemiology and Control of Notifiable Animal Diseases

Investigation published in Frontiers in veterinary science

There are a number of criteria by which an animal disease is classified as notifiable; the most important are typically related with its potential to spread internationally, as well as its impact on the health of domestic livestock, wildlife and, not the least, on human health (1). Because of the above, surveillance, early detection, control, and eradication of these diseases is of critical importance for countries in order to maintain or improve their animal health status. This requires the collaboration of all stakeholders involved (e.g., animal health authorities, livestock industry, and ve… Read more

Salmonella Surveillance Systems in Swine and Humans in Spain: A Review

Investigation article published in Veterinary sciences

Non-typhoid salmonellosis is a common and problematic foodborne zoonotic disease in which pork and pork products can be an important potential source of infection. To prevent this disease, important efforts to monitor the situation in the main source, livestock, are conducted in most developed countries. In the European Union, European Food Safety Agency (EFSA) and European Center for Disease Control (ECDC) compile information at the member-state level, even though important differences in production systems and surveillance systems exist. Here, Salmonella surveillance systems in one of the ma… Read more

Comparison of individual, group and environmental sampling strategies to conduct influenza surveillance in pigs

BMC Veterinary Research publish this investigation article

BACKGROUND: Influenza A virus (IAV) is an important pathogen in pigs that affects productivity and has important public health implications because of its zoonotic nature. Surveillance is central to the control of influenza, however, detection of IAV infections can be challenging in endemically infected herds with low prevalence of infection. METHODS: In groups of suckling (18-21 days of age) and growing (35-45 days of age) pigs, we compared various sampling approaches to detect, isolate and sequence IAV using individual (nasal swabs, nasal wipes and oropharyngeal swabs), grou… Read more

Surveillance and control of African Swine Fever in free-ranging pigs in Sardinia

Investigation published in Transboundary and Emerging Diseases

African swine fever (ASF) is a notifiable infectious disease, caused by the ASF virus (ASFV), which is a DNA virus belonging to the family Asfarviridae, genus Asfivirus. This disease has gained importance in the last decade after its spread in several countries in Eastern and Central Europe, and more recently, in China. Despite the efforts made to eradicate it, ASF is still present on the Mediterranean island of Sardinia (Italy) and has been since 1978. ASF risk factors on the island have been analysed in previous studies; the role of free-ranging pigs in virus persistence has been suggested, … Read more

A new test to detect antibodies against Mycobacterium tuberculosis complex in red deer serum

The Veterinary Journal publish this investigation article

Red deer (Cervus elaphus) farming is a growing economic activity worldwide. However, the capacity of this species to act as reservoir of animal tuberculosis (TB) poses a threat to other wildlife and to livestock. Diagnostic assay accuracy in this species is therefore highly relevant for prevention and control measures. Our aim was to evaluate the diagnostic performance of the protein complex P22, obtained from Mycobacterium bovis derived purified protein derivative (bPPD), as a candidate antigen for the detection of antibodies against Mycobacterium tuberculosis complex (MTC). We assessed the p… Read more

Evaluation of the McLintock syringe as a cause of non-specific reactions in the intradermal tuberculin test used for the diagnosis of bovine tuberculosis

Investigation article published in Research in Veterinary Science

The objective of this study was to elucidate whether the use of the McLintock syringe, used to inject tuberculin in cattle in several countries and based on an intradermal inoculation by needle, may, in itself, cause skin reactions that can be interpreted as positive reactions regardless of the real tuberculosis (TB) infection status of the animals. Forty-four cattle from an officially TB-free (OTF) herd were selected for the experiment. Each animal received four inoculations [one with sterile phosphate buffer saline (PBS) with 10% of glycerol and three with bovine purified protein derivative… Read more
