To the Editor: Since its first emergence in the human population in spring 2009 (1–3) infections with pandemic (H1N1) 2009 virus have been reported in pigs, turkeys, and some carnivore species (4,5). The pandemic (H1N1) 2009 virus can be experimentally transmitted between pigs (6). The reported transmissibility of the virus raises the question as to whether(More)
The incursion of pandemic (H1N1) 2009 virus (pdmH1N1) into the German pig population was investigated in a serosurvey and by virological means between June 2009 and December 2012. Analysis of 23,116 pig sera from a total of 2,666 herds revealed 224 herds that reacted with pdmH1N1 but not with the prevalent avian-like H1N1 swine influenza virus. Sixty-six(More)
The objective of this study was to characterize the immune response induced by a live attenuated Salmonella Enteritidis (SE; ade(-)/his(-)) vaccine using an intraperitoneal immunization/challenge model in susceptible wild-type and cytokine-deficient BALB/c mice. In wild-type mice, inoculation of the SE live vaccine induced a protective immune response(More)
The aim of this study was to examine the duration of immunity of different vaccination schemes using the S. enteritidis live vaccine Gallivac Se and the S. enteritidis-S. typhimurium inactivated vaccine Gallimune Se+St. Three groups of Lohman Brown chickens were used. Group one was vaccinated three times orally with Gallivac Se at weeks one, seven and 13 of(More)
A total of 1026 serum samples from 388 pigs from three Bavarian rearing farms in the region of Swabia were investigated in the course of investigations into the development of antibodies against Influenza A virus subtypes H1N1, H1N2 and H3N2 by haemagglutination inhibition test during the period from November 2002 to February 2004. There were no signs of(More)
LPS antibody reaction of S. Typhimurium was detected in a total of 111 two- to ten-week-old pigs, which had been exposed to experimental oral infection with this serovar in 16 separate experiments. The total antibody level was determined according to the meat juice ELISA provided for the Salmonella control programme and the antibody concentrations of the(More)
For vaccine licensing data about efficiency and duration of protection are essential. Within the scope of the developement of a new subunit vaccine against Actinobacillus pleuropneumoniae (A.pp.) the protective efficiency over the whole length of the fattening period must be proven. This required infection experiments in finishing pigs. Eight pigs in the(More)
In Germany now, the recognition of Salmonella infections in pig herds is based on three different commercial tests detecting antibodies against Salmonella-derived lipopolysaccharide (LPS). However, a serious disadvantage of these tests, used so far, is the restricted detection of antibodies belonging predominantly to the immunoglobulin class g (IgG).(More)
Inactivated whole-virus vaccines against porcine parvovirus (PPV) can prevent disease but not infection and virus shedding after heterologous virus challenge. Here, we showed that the same is true for a homologous challenge. Pregnant sows were vaccinated with an experimental inactivated vaccine based on PPV strain 27a. They were challenged on day 40 of(More)
Oedema disease is one of the major diseases in pigs during the nursery period. It is caused by Shigatoxin 2e producing strains of Escherichia coli. In order to combat the disease, the metaphylactic use of colistin sulphate and zinc oxide is widely spread. Additionally, special feeding regimens such as the reduction of the amount of crude protein and the(More)
