Study On Control Measures And Epidemiological Investigation Of My Coplasmal Penumonia Of Black Swine In Xiangxi

Mycoplasma hypneumoniae is the causative agent of mycoplasmal pneumonia in swine (MPS). Infection with M.hyopneuoniae alone induces a Chronic exposure to sexually transmitted diseases.Mycoplasma hyopneumoniae infection on the Xiangxi pig farming had a greater harm. Therefore, this experiment occurred on a pig farm Guzhang pigs were infected with Mycoplasma pneumoniae isolation and identification of pathogenic microorganisms, and for the2010-2012swine enzootic pneumonia epidemics were investigated. In order to effectively science for the prevention and control of swine enzootic pneumonia, comprehensive measures for prevention and control were studied.Now the main work report as follows1、Mycoplasma were existed in10swine from Hunan Guzhang, in order to find out this Mycoplasma belong to withch category, microscopic observation of the morphology of pathogenic microorganisms, a preliminary judge for mycoplasma infection. PCR test was developed to further determine the strains with one pair of primers designed according to the sequence of the MPS’16S rRNA gene. Ultimately get the results, the farm’s10piglets were infected with Mycoplasma hyopneumoniae.Mycoplasma pneumoniae on isolated susceptibility testing, according to this result the farms were guiding medication.2、For2012across the state of Xiangxi black pig farms were carried out to investigate the epidemic situation of swine enzootic pneumonia that prevention and control measures of black swine enzootic pneumonia is not properly, resulting in high morbidity and mortality of piglets, nursery pigs, piglets incidence accounted for54%of the total cases, the number of cases of nursery pigs accounted for the total number of cases44%, piglet mortality accounted for72%of all deaths; nursery pig death accounted for27%of the number of deaths.From the serum of inspection results show that while adult swine and swine morbidity and mortality is not high, but the body was stilly detected with swine enzootic disease.3、To make a summary of comprehensive control measures of Xiangxi Black Pig Mycoplasma hyopneumoniae. In order to make aquaculture, the most important thing is to carry out scientific feeding and management, as well as the development of immunization programs, so that these areas can improve pig production Xiangxi effective, thus enabling farmers to maximize the economic benefits.
