Mycoplasma gallisepticum (MG) infects chickens, causes chronic respiratory diseases (CRD) and severely damages the poultry industry. It has been suggested that micro-ribonucleic acids (miRNAs) are involved in microbial pathogenesis. Here, we identified miRNAs that are associated with MG infection in chicken lungs at 3 and 10days post-infection by deep sequencing. Thirty-six down-regulated and 9 up-regulated miRNAs belonging to 31 miRNA families were detected at 3days post-infection, whereas 50 down-regulated and 18 up-regulated miRNAs belonging to 41 miRNA families were found at 10days post-infection...

Mycoplasma gallisepticum (M. gallisepticum) remains one of the most important diseases in poultry production. Controlling the impact of the disease is done by eradication of positive breeder flocks or by vaccination and medication. A widely used molecule in medication programs is tiamulin, a pleuromutilin antibiotic. Since recent data on the in vivo efficacy of this molecule are scarce, 2 challenge studies were conducted using a recently isolated M. gallisepticum strain belonging to the wildtype population with regard to its tiamulin and tetracycline minimum inhibitory concentration (MIC)...

Campylobacter is one of the major foodborne pathogens that result in severe gastroenteritis in humans, primarily through consumption of contaminated poultry products. Chickens are the reservoir host of Campylobacter, where the pathogen colonizes the ceca, thereby leading to contamination of carcass during slaughter. A reduction in cecal colonization by Campylobacter would directly translate into reduced product contamination and risk of human infections. With increasing consumer demand for antibiotic free chickens, significant research is being conducted to discover natural, safe and economical antimicrobials that can effectively control Campylobacter colonization in birds...

Carotenoids are used in animal nutrition mainly as sensory additives that favourably affect the colour of fish, birds and food of animal origin. Various analytical methods exist for their quantification in compound feed, reflecting the different physico-chemical characteristics of the carotenoid and the corresponding feed additives. They may be natural products or specific formulations containing the target carotenoids produced by chemical synthesis. In this study a multi-analyte method has been developed that can be applied to the determination of all ten carotenoids currently authorised within the EU for compound feedingstuffs...

Microbial aerosol whose species and concentrations are closely related to human health is ubiquitous. The effect of microbes on human and animal health and production performance is, in many cases, caused by the spreading of air. Samples in this experiment were from a live poultry market (LPM) in Tai'an, China, collected three times a day (8 am, 14 pm, and 20 pm) over three consecutive days each month for 11 months (Original sampling plan was a year, the government due to the environmental protection, the was LPM closed)...

Salmonella enterica subsp. enterica serovar Gallinarum biovar Pullorum (Salmonella Pullorum) is highly adapted to chickens causing an acute systemic disease that results in high mortality. Vaccination represents one approach for promoting animal health, food safety and reducing environmental persistence in Salmonella control. An important consideration is that Salmonella vaccination in poultry should not interfere with the salmonellosis monitoring program. This is the basis of the DIVA (Differentiation of Infected and Vaccinated Animals) program...

In this study, a simulation model was used to assess the epidemiological and economic impacts of the routine vaccination strategy for H5N1 in China at the national level. The results of the simulation show that a routine vaccination strategy at the national level could have a substantial impact on decreasing H5N1 outbreaks; it could therefore markedly reduce the severity and duration of an H5N1 epidemic at the national level in China. Under a routine vaccination programme, when a flock is infected, the number of depopulated birds could be reduced by approximately 91%, the outbreak duration could be reduced by one-fourth, and the probability of an H5N1 outbreak could be reduced to 51...

Ornithobacterium rhinotracheale is a widely distributed rod-shaped gram-negative bacterium that infects several avian species including chickens and turkeys. It is associated with respiratory signs, growth retardation, mortality, and reduced egg production thus causing severe economic losses to the poultry industries. In this study, 37 field isolates of O. rhinotracheale, collected from various locations in Hungary between 1997 and 2015, were identified and molecularly characterized by the analysis of partial 16S rRNA gene sequences, enterobacterial repetitive intergenic consensus (ERIC)-PCR and random amplified polymorphic DNA (RAPD) PCR assays with the OPG11, OPH19, and M13 primers...

REVIEW
Michael H Kogut, Ryan J Arsenault
The adaptation of Salmonella enterica to the eukaryotic host is a key process that enables the bacterium to survive in a hostile environment. Salmonella have evolved an intimate relationship with its host that extends to their cellular and molecular levels. Colonization, invasion, and replication of the bacteria in an appropriate host suggest that modification of host functions is central to pathogenesis. Intuitively, this subversion of the cell must be a complex process, since hosts are not inherently programmed to provide an environment conducive to pathogens...
