The objective of the present study was to assess the applicability of qPCR to quantify PCV-2 loads in pooled serum samples as an easy-to-use PMWS diagnostic tool at the herd level.

This is, to the authors’ knowledge, the first published study to determine the bacterial flora in skin and colostral milk samples of a limited number of sows with clinically healthy mammary glands.

To determine the prevalence of ASF in Senegal in 2006, we tested serum specimens collected from a sample of pigs in the 3 main pig-farming regions for antibodies to ASF virus.

Infection with I suis during the suckling period can have an impact on postweaning performance. Thus, calculations of the economic impact of coccidiosis need to include the effect of slower growth rates in the first few weeks after weaning, as well as a reduction in suckling pig performance.

Swine outbreaks of pandemic influenza A (pH1N1) suggest human introduction of the virus into herds. This study investigates a pH1N1 outbreak occurring on a swine research farm with 37 humans and 1300 swine in Alberta, Canada, from 12 June through 4 July 2009.

A herd of pigs being reared for breeding and fattening, in which there had been incidences of abortion and wasting, reduced growth rates and an increase in mortality for the past year, were tested for Mycobacterium infection by pathological examinations, skin test, serology and Mycobacterium culture.

Previous studies have linked levels of porcine endogenous retroviruses (PERV) with poor health and disease in pigs. To determine the levels of expression of PERVs and their potential association with disease expression, real-time reverse transcriptase (RT) PCR assays were used to assess PERV-ABC, PERV-C and PERV-A/C levels in three commercial swine operations in the United States.

The results of this study indicates a low risk of prolonged carriage of FMD virus in the human nasal cavities after exposure to infected animals.

A research protocol was designed to eradicate the virus in pigs sourced from a PRCV positive sow herd. The sow herd is a 150 farrow to finish herd, under one roof, and is PRRS and Mycoplasma hyopneumoniae negative. Forty piglets were weaned from nursing gilts/sows at 5 days of age and removed to a separate nursery which had been thoroughly disinfected and cleaned.

Feeding low CP, AA supplemented diets can help to improve poor growth performance and enteric disorders of the weaned pigs.

The results obtained in this study suggest that UV(254) is an effective means to inactivate PRRSV on commonly encountered farm surfaces and materials and inactivation can be accomplished following 10min of exposure.

Considering the results of this study, O. porcinus is a reservoir for ASFV and most likely acts as vector for ASFV in Madagascar, but its apparent restricted distribution may limit its role in the epidemiology of the disease in domestic pigs.

The objective of this study was to evaluate the efficacy of administering potassium penicillin G via drinking water to weaned pigs to reduce mortality and spread of infection caused by Streptococcus suis.

The aim of the current study was to develop and test a multiple-locus variable-number tandem-repeat analysis (MLVA) method that could be used in basic veterinary diagnostic microbiology laboratories equipped with PCR technology or in more advanced laboratories with access to capillary electrophoresis.

Insects such as house flies (Musca domestica) and German cockroaches (Blattella germanica) can move freely between animal waste and food and may play a significant role in the dissemination of antibiotic resistant bacteria within and between animal production farms and from farms to residential settings.

Pleuritis in slaughter pigs has increased in recent years in the Netherlands. The aim of the present study was to determine what respiratory pathogens were involved in pleuritis.
