PRRSV SUCCESSFULLY HANDLED WITH WHOLE HERD VACCINATION. CONCEPT AND BIOSAFETY ANALYSIS

Five farmers supplied by one piglet breeder increasingly complained of disease-susceptible and poorer-growing pigs and therefore an increased need for antibiotic treatment. The piglet breeding facility is a 2 side production system with 480 sows, located in lower Saxony, Germany. The weaned pigs are kept in outdoor climate barns, 1.5 km away from the sows.

AN AUTOMATED CLASSIFICATION SYSTEM FOR PRRS ORF5 SEQUENCES

A classification system based on PRRS ORF5 sequences would be useful to assess progress in control program and for surveillance purposes. The objective of this study was to evaluate the feasibility of an automated system that could be used for very large datasets and would consistently give reliable results over time.

SURVEILLANCE OF PRRS VIRUS STRAINS-HOW NEW TOOLS CAN SUPPORT CONTROL INITIATIVES

PRRS sequencing (ORF5) is widely used in Quebec, Canada. Through several signed agreements with veterinarians, a structure was established allowing near real-time transfer of sequences to our research team from 3 different laboratories in Quebec. As a result, our database has grown to nearly 6000 sequences, with an annual averaged increase of 450 sequences. This database has allowed the development of several tools that can be used for surveillance.

CORRELATION BETWEEN SERUM POOLS, ORAL FLUID AND FECAL SOCK SAMPLES FOR PCV2 QUANTIFICATION IN A DANISH FINISHER HERD

Porcine circovirus type 2 (PCV2) is often quantified by qPCR from pooled serum samples or penwise oral fluid samples (OF). PCV2 can also be detected in feces. The objectives of the study were to compare PCV2 viral loads in pooled serum samples, OF and FS collected in the same pens and to assess the impact of individual pig´s viral load on a pooled serum sample.

THE EFFECT OF POOLING TWO DIFFERENT TYPES OF SAMPLES TO DETECT TYPE 1 PRRS VIRUS ON PRE-WEANING PIGLETS IN AN ENDEMIC POSITIVE HERD AND PRACTICAL IMPLICATIONS

Most of the time, breeding herd stability against PRRSv is assessed by sampling 30 due-to-wean piglets in a farrowing batch and pooling the samples by five to test them with a RT-qPCR test. The aim of this study was to compare the capacity to detect PRRSv in pre-weaning piglets using 2 different types of samples per litter and pooling them by five.

CHARACTERIZATION OF PRRS VIRUS AND EPIDEMIOLOGICAL ASPECTS IN SWINE FARMS IN COSTA RICA

The Porcine Reproductive and Respiratory Syndrome (PRRS) was firstly recognized clinically in the EU in 1987 and spreaded through Europe and America. This virus has two genotypes: with type 1 predominating in Europe and type 2 in North America and Asia. The aim of this study was to identify and to characterize the PRRS virus circulating and to estimate the prevalence in pig farms in Costa Rica.

PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME VIRUS DETECTION IN WEANINGAGE PIGLETS IN 120 FRENCH FARMS

To assess the stability of a sow herd against Porcine Reproductive and Respiratory Syndrome virus (PRRSv), PCR on blood in weaning-age piglets is regularly implemented. This work describes the results obtained in 120 farms.

PCV2GENOTYPES : EPIDEMIOLOGICAL SURVEY IN THE WEST OF FRANCE

Since 2004 a worldwide shift of porcine circovirus type 2 (PCV2) genotypes was observed from PCV2a towards PCV2b and more recently PCV2d (since 2012).

FIRST DETECTION OF PORCINE PARVOVIRUS 7 IN POLAND

In the last years several novel parvoviruses (PPV) were discovered in pigs worldwide. The most recently discovered porcine parvovirus species is PPV7, which was reported in USA and China to date. The aim of the study was to present the first evidence of PPV7 in Polish pigs

PRRSV TYPE 1 TRANSMISSION VIA PIGLET TRAILERS – RELEVANCE FOR SPREADING?

A field study was performed in Germany to evaluate the role of transport vehicles as a source of transmission of porcine reproductive and respiratory syndrome virus (PRRSV) to susceptible pigs. Risk factors for transmission of PRRSV type 2 via transport vehicles has been described, while little is known about PRRSV type 1 transmission via trucks in Europe.

DETECTION OF HEPATITIS E VIRUS ON SWINE FARMS IN POLAND.

Hepatitis E virus (HEV) is the causative agent of hepatitis E in humans. Pigs are one of the main reservoirs for genotypes 3 and 4. Little is known about the circulation of HEV on swine farms and the effect of infection on health status of pigs. The objectives of the study were to demonstrate HEV circulation on Polish swine farms and the presence of the virus in serum, oral fluid and feces.

PHYLOGENETIC ANALYSES OF PORCINE CIRCOVIRUS TYPE 3 INFECT A SWINE PRODUCTION SYSTEM IN MEXICO CITY

In the United States and China, the presence of porcine circovirus type 3 (PCv3) has been described emerging disease that occurs mainly causing reproductive failures in females. Currently, in Mexico the presence of PCv3 has not been reported, however, in recent years has been detected increase in the number of cases of sows with reproductive failures, discarding the presence of other infectious agents present in national territory.

IMPLEMENTATION OF THE 5 STEPS PROCESS PLATFORM FOR PRRS CONTROL IN A FARM IN SPAIN

PRRS is one of the most damaging diseases in the swine industry, having negative effects typically affecting breeding herd reproductive parameters as well as pig productivity parameters. Controlling the infection is key to keep the systems producing at target levels and involves sow herd stabilization as well as an active pig protection.
