Given the primacy of Iowa in pork production for the U.S. and global markets, we sought to understand if the same relationship with traditional environmental justice (EJ) variables such as low income and minority populations observed in other concentrated animal feeding operation (CAFO) studies exists in the relationship with swine CAFO densities in Iowa. We examined the potential for spatial c...

BACKGROUND Recent research has demonstrated that many swine and swine farmers in the Netherlands and Canada are colonized with MRSA. However, no studies to date have investigated carriage of MRSA among swine and swine farmers in the United States (U.S.). METHODS We sampled the nares of 299 swine and 20 workers from two different production systems in Iowa and Illinois, comprising approximatel...

Early experiments indicated that the bacterium, Hemophilus influemae suis, (1) administered intranasally to swine, conferred no immunity to swine influenza (2). These had not been intended to test the possible value of the organism for use as a prophylactic agent in controlling swine influenza, and no experiments in which the bacterium was administered in other ways than intranasally were condu...

Glutaraldehyde, 0.2%, in a 1:100 (wt/vol) ratio, inactivated four animal viruses (foot-and-mouth disease, swine vesicular disease, African swine fever, hog cholera) in swine heart tissues during 11-day exposures at 22 to 26 degrees C.

By use of a photometric method which objectively distinguishes between homologous and heterologous antibody reactions, the age distribution of specifically reacting swine and Asian antibodies present in sera of persons not recently exposed to either virus was established. The findings support the thesis that the unique distribution by age of swine and Asian antibodies recognizes two past period...

We report here the complete genome sequence of a triple-reassortant H1N1 swine influenza virus strain, A/swine/Guangxi/BB1/2013 (H1N1) (GXBB1), isolated from a swine in the Guangxi Province of southern China in 2013. We obtained the complete genome sequence of the GXBB1 virus. Sequence analysis demonstrated that this H1N1 virus was a triple-reassortant swine influenza virus (SIV) whose genes or...

On November 13, 1997 the South Carolina Department of Health and Environmental Control Approved regulation R.61-43, Standards for the Permitting of Agricultural Animal Facilities. The State Legislature approved these standards on June 26,1998. The primary purpose listed for setting these standards is “To establish standards for the growing or confining of swine, processing of swine manure and o...

Human and swine influenza viruses were regularly neutralized by their homologous immune sera. However, the sera of animals convalescent from infection with either the swine or human influenza virus possessed little, if any, neutralizing capacity for the heterologous virus. Hyperimmunization of animals against swine influenza virus tended to increase the neutralizing capacity of their sera for h...

Given their free-ranging habits, feral swine could serve as reservoirs or spatially dynamic 'mixing vessels' for influenza A virus (IAV). To better understand virus shedding patterns and antibody response dynamics in the context of IAV surveillance amongst feral swine, we used IAV of feral swine origin to perform infection experiments. The virus was highly infectious and transmissible in feral ...

swine flue is a highly contagious acute respiratory disease caused by a subtype of influenza a virus. herein we present three patients with h1n1 infection complicated with pulmonary thromboembolism. the patients had chest pain and unexplained dyspnea. imaging studies showed bilateral hilar predominance. computed tomographic angiography confirmed bilateral thromboembolism (an unusual presentatio...
