Abstract
Methodology As part of a broad clinical trial comparing the efficacy of two M. hyo vaccines, serological investigations took place in 40 animals of the negative control group (subdivided into 2 subgroups of 20 animals each). As the case with the remainder of the control group, these animals had previously received a single administration of 2 ml isotonic saline deep intramuscularly in the neck at approximately 3 weeks of age. Blood samples were taken at the piglets' entry into the fattening unit (week 10 of age), in the middle of the fattening period (week 17 of age) and at the end of the fattening period (week 25 of age). Employing ELISA technology, the samples were investigated for both M. hyo and PRRSV antibodies. The pigs were not vaccinated against PRRSV.
Highlights
The study aimed at investigating the occurrence of antibodies against the porcine pathogens Mycoplasma hyopneumoniae (M. hyo) and PRRS virus (PRRSV) in the serum of pigs aged 10 to 25 weeks and kept under field conditions in Germany
As part of a broad clinical trial comparing the efficacy of two M. hyo vaccines, serological investigations took place in 40 animals of the negative control group
The serological investigations revealed that at the first 2 sampling time points (10 and 17 weeks of age, respectively) no antibodies against M. hyo were present in the serum of the piglets
Summary
OCCURRENCE OF NATURAL INFECTION WITH MYCOPLASMA HYOPNEUMONIAE AND PORCINE REPRODUCTIVE RESPIRATORY SYNDROME VIRUS (PRRSV) IN PIGS UNDER GERMAN FIELD CONDITIONS Objective The study aimed at investigating the occurrence of antibodies against the porcine pathogens Mycoplasma hyopneumoniae (M. hyo) and PRRS virus (PRRSV) in the serum of pigs aged 10 to 25 weeks and kept under field conditions in Germany.
