The bacterial pathogen Mycoplasma synoviae can cause subclinical respiratory disease, synovitis, airsacculitis and reproductive tract disease in poultry and is a major cause of economic loss worldwide. The M. synoviae strain MS-H was developed by chemical mutagenesis of an Australian isolate and has been used as a live attenuated vaccine in many countries over the past two decades. As a result it may now be the most prevalent strain of M. synoviae globally.

Salmonellosis is one of the major leading foodborne zoonotic diseases reported worldwide, poultry and poultry products including table eggs were reported as the most important source for foodborne outbreaks in humans. The present study was designed to determine and compare the occurrence of Salmonella serovars by cultural and molecular (PCR) methods in processed, unprocessed and desi table eggs available in the markets, resistance pattern of isolates for commonly used antibiotics and decontamination of table eggs using chlorine and peracetic acid.

Mycoplasma gallisepticum and Mycoplasma synoviae are important poultry pathogens responsible for high economic losses to the poultry industry in term of mortality, poor weight gain and decrease of feed efficiency in broiler chickens and reduction of egg production in layer chickens and turkeys. Serum plate agglutination (SPA), hemagglutination inhibition (HI) and ELISA are the most common serological techniques used for rapid detection of infection and the adoption of control measures of the diseases.

Available as a dust, wettable powder, and emulsifiable concentrate, permethrin is used on more than 10 percent of the birds (layers, breeders, pullets) treated for ectoparasites. Treatment is most often applied to birds at a rate of 1 gallon of spray (0.004 pound of active ingredient) spray per 100 birds. Premise application at the same concentration is made at a rate of 1 to 2 gallons spray per 1,000 square feet of surface area. Dust formulations (0.25 percent) are applied to birds (dust boxes) and premises (litter) at a rate of 1 pound (0.003 pound of active ingredient) per 100...

Avian Influenza viruses are extremely common in nature. Although many wild birds may harbour influenza viruses, they are found most commonly in wetland birds and birds from aquatic environments, such as ducks, geese, swans, gulls and waders (Olsen et al. 2006). These birds carry the low pathogenicity strains of avian influenza (LPAIs); these can occasionally cross over to domestic poultry such as chickens and turkeys and cause mild disease, but they do not seem to pose a significant risk to humans who become infected.

Respiratory disease complex: Under field conditions, pathogens often interact with not only the host (bird) and its environment, but also one another. For example, day-old chicks arriving infect- ed from the hatchery (vertical transmission) and remaining chroni- cally infected for life are susceptible to other respiratory diseases such as infectious bronchitis or Newcastle disease.

Immunosuppression significantly decreases the ability of young poultry to respond effectively to standard vaccinations, and also predisposes them to infection by other specific pathogens. How- ever, sub-clinical immunosuppression is often not readily appar- ent to the farmer, and therefore a common “silent” cause of significant economic losses. Pathogens causing such infectious disease conditions are termed “erosive” for site productivity (Shane, 2004).

This manual identifies areas of risk common to most poultry enterprises and appropriate measures to minimise these risks. When undertaking the risk assessment underpinning the farm-specific biosecurity measures, it is important to take into account all factors that may impact on the biosecurity of the production area.
