Bacterial diseases in poultry
Bacterial diseases comprise approximately half of the non–outbreak-related mortality in broiler breeders and commercial layers. During the first week of a broiler's life, approximately 50% of the mortality may be caused due to bacterial infections. Outbreaks due to bacterial infections may increase the mortality dramatically and in some cases almost eradicate flocks. E. coli and Gram-positive cocci infections are responsible for mortality and production losses in poultry of all age groups and all production systems and may be regarded as multifactorial. Subsequently, efforts in understanding and controlling these infections are highly important. Although necrotic enteritis is primarily a disease affecting young chickens, this infection is of major significance in any production system. Besides increased mortality, the production losses observed in subclinical infections may be dramatic.
The bacteria M. synoviae (MS) is a member of the mycoplasma genus. It causes disease in the joints, bones, respiratory tract and oviduct of birds. A MS infection can result in big economic losses due to a drop in egg production and eggshell quality. During last few years, it was noticed that some layer and breeder flocks faced a drop in egg production of ~10%, some after the peak, while other before reaching the peak of production, along with poor eggshell...

Mycoplasm synoviae is burning issue in broiler breeders. Though we adapted to strict bio security measures ELISA is positive for MS when the flocks come to later part of the production period. We are having multi age farms and we did MS killed vaccines but still problem persist. What is the best solution to this? ...

Introduction Worldwide, necrotic enteritis (NE) leads to important production losses, increased feed consumption and mortality rates, and a reduced welfare of broiler chickens [1–4]. The causative agent of NE is Clostridium perfringens, a Gram-positive spore forming bacterium which occurs ubiquitously in the environment, in feed and in the gastrointestinal tract of animals...

Introduction Brazil currently ranks as the major exporter of chicken meat in the world with markets in more than 150 countries. Salmonella enterica (Salm. enterica) is one of the most important bacterial pathogens that can cause foodborne illness (Schroeder et al. 2006). It is often transmitted to people by eggs and other poultry products (Hogue et al. 1997). The Brazilian poultry...

Introduction Campylobacter infections pose a serious public health problem; the incidence of campylobacteriosis has progressively increased in developed countries, and the pathogen is now considered the leading cause of bacterial gastroenteritis throughout the world (Humphrey et al. 2007; FAO⁄WHO, 2009). Thermophilic Campylobacter jejuni and Campylobacter coli are the most...

Introduction Heavy parental flock Hibro PG, brought up in raising facilities, was moved into production facilities. The upbringing of 16800 hens was done in two objects in a single location, and the upbringing of 2150 roosters in the third object of the same location. During the upbringing, no disorders of health was noticed among animals, and an immunoprophylaxis program made in the Scientific Institute for Veterinary...

Introduction Salmonellosis is a zoonotic disease produced by the Gram-negative enteric bacterium Salmonella. Salmonella are not restricted to particular host species, with more than 2500 serotypes having been described mostly belonging to the species Salmonella enterica (1), with most having asymptomatic colonization of the gastrointestinal tract of animals. The most...

Use of dietary plasma in pre-starters for broilers may improve growth and health. Early nutrition of the broiler chicken is becoming more important as more knowledge is gained about the positive correlation between early growth rate and market weight and also the impact early growth and development have on the uniformity of carcass weight and composition. All of these factors become...

Abstract
Salmonella monitoring and control is a priority in the EU. Control strategies have been implemented on a voluntary basis but are also imposed by various authorities. Obligatory and voluntary monitoring programs provide valuable information on the present status of Salmonella contamination at the different levels of the poultry production chain. In this...
