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.
Introduction Avibacterium paragallinarum (Av. paragallinarum) is a gram-negative bacterium that has been isolated worldwide and is the aetiological agent of infectious coryza (IC), a disease that contributes to significant economic losses in the poultry industry. Clinical signs of IC include nasal discharge, facial swelling, and lacrimation. This disease is associated with reduced egg production, poor growth, and high morbidity [1, 2]. However, in cases with secondary...

Avibacterium paragallinarum is the etiologic agent of infectious coryza, an acute respiratory disease of chickens, which is globally distributed and causes serious economic losses in the poultry production industry. It is a Gram-negative, nonmotile, capsulated, facultative anaerobe belonging to the family Pasteurellaceae and is classified in 9 serovars distributed in 3 serogroups (A, B, and C) (1, 2). The study of its genome and virulence factors (hemagglutinin antigen, capsule,...

Bacterium Avibacterium paragallinarum is the causative agent of infectious coryza. This is an acute respiratory disease of economic significance in poultry and leads to a decrease in egg production and failure or retardation of egg laying [1]. Serological classification of A. paragallinarum is based on the presence of specific hemagglutinins (HAs). A. paragallinarum strains/isolates are traditionally serotyped by means of 2 schemes: the Page scheme, which...

Poultry producers need support to overcome the challenges posed by reducing the use of antibiotics. Phileo has constructed a post-antibiotic program founded on four pillars of quality poultry production: farm management, nutrition, immunity, and gut health. These...

Live ts mycoplasma vaccines were created to be safe but still immunogenic. So how can we assess this immunogenicity in the field? This bulletin condenses the experience of 20 years trying to monitor vaccine response and differentiate problems from normal responses. Various approaches have been taken to improve serological monitoring (for example, cloned homologous antigens) and understand problems but the conclusion is that humoral antibody is not the mechanism of protection of these...

Fats are a key component of poultry feeds. Fats supply essential fatty acids, help the absorption of fat-soluble vitamins and are the most efficient source of energy. Heated and oxidized fats contain peroxidation compounds that change the odor and palatability of the fat, while depressing feed intake and...

As we explained in this article, overgrowth of Avian Pathogenic Escherichia Coli (APEC) in the digestive system is the second most important route of entry of APEC into the body of the bird. Therefore, avoiding the colonization of the digestive system by APEC is key to prevent colibacilosis. Drinking water as a...

Background Antimicrobial resistance (AMR), is one of the biggest threats to food safety and considered a One-Health issue with the potential of spreading to other countries since resistant pathogens do not recognize boundaries [1, 2]. Recently, we have shown the transmission of AMR E. coli among chickens, humans, and the poultry environment [3, 4]. Globally, antimicrobial agents are used in food animal production to ensure good health and productivity of the animals [5–7]....

Necrotic enteritis (NE) is one of the most important diseases of the world broiler industry which costs over six billion dollars annually. There has been a concerted effort to control and minimise the effects of NE that have arisen since the EU ban of in-feed antibiotics in the poultry industry. Organic acids have been used as alternatives to in-feed antibiotics for maintaining good gut health of poultry by suppressing the growth of pathogenic bacteria, resulting in improved performance...

The digestive system is in charge of transforming the feed into assimilable nutrients, a key process in commercial poultry farming to maintain health status and obtain good productive results. It also works as a selective barrier to protect the organism from harmful agents. Any disease that affects the function of the digestive system will lead to a loss of productive performance, such as growth retardation, poorer conversion rates and feed efficiency, and even high mortality. As an...

I. INTRODUCTION
Antimicrobial resistance (AMR) is considered one of the biggest threats to human and animal health today (Australian Government, 2015; O’Neill 2016) and all users of antimicrobial agents have a responsibility to ensure that these agents are only used when necessary.
The Australian poultry industry takes the issue of AMR very seriously and has a long history of developing and introducing initiatives to enhance infection prevention and...

The use of Bacillus species as probiotic supplements is expanding rapidly and these products demonstrate immune stimulation, antimicrobial activities, enzyme production and competitive exclusion as the most prevalent modes of action (Grant et al., 2018; Hmani et. al., 2017; Reis et al., 2017).
The objective of this study was to evaluate the effect of a multi-strain Bacillus-based directly fed microbial (DFM) and its three single strains on performance of broilers challenged with a...

Modern animal feeding includes prophylactic approaches for supporting intestinal homeostasis and immunity, in order to avoid dysbiosis, diseases, and need for antimicrobial medication. According to the principles of the One Health concept, the well-being of humans, animals and the environment are all connected, and at these times of a pandemic, avoiding the excess usage of antibiotics in animal farming is more important than ever. Pro-, pre- and synbiotics Prebiotics and...

Fowl cholera, caused by Pasteurella multocida, remains a major problem of poultry worldwide. In the current report, we describe an outbreak in free range organic broilers. In addition to culturing samples from dead broilers, we attempted to isolate P. multocida from feral cats trapped on the farm. The isolates were identified by PCR as P. multocida and then serotyped using the Heddleston scheme and genotyped using both a multilocus sequence typing (MLST) method and an enterobacterial...

1. Introduction Recently, oxidative stress has become a major concern as a life threatening and a chronic-disease mediator [1–3]. The reactive oxygen or nitrogen species (ROS, RNS) are normally generated during the respiratory chain reaction in the mitochondria. Nevertheless, the excessive production of such ROS and RNS induces oxidative stress, homeostasis imbalance and subsequent pathological conditions [4]. Bacterial infection activates immune cells and induces...

1) Mycoplasma synoviae (MS) does nothing.
2) MS does not have airborne spread.
3) It is not MS because there is no joint involvement.
4) You must use F strain in the first stage of eradicating MG.
That MS does nothing is an interesting view. There is great variation in the potential of MS strains to cause disease but avian Mycoplasma experts worldwide agree that MS is a pathogen, it has its own chapter in Diseases of Poultry describing its pathogenic potential...
