Based on bacterial genomic data, we developed a one-step multiplex PCR assay to identify Salmonella and simultaneously differentiate the two invasive avian-adapted S. enterica serovar Gallinarum biotypes Gallinarum and Pullorum, and the most frequent, specific, and asymptomatic colonizers of chickens, serovars Enteritidis, Heidelberg, and Kentucky.

Bacteriophage f18SE was isolated from poultry sewage in Olmue, Chile, and lytic activity was demonstrated against Salmonella enterica serovar Enteritidis and serovar Pullorum strains. This bacteriophage has a 41,868-bp double-stranded DNA (ds-DNA) genome encoding 53 coding sequences (CDSs) and belongs to the family Siphoviridae, subfamily Jerseyvirinae.

Antimicrobial resistance (AMR) is a global health threat, and antimicrobial usage and AMR in animal production is one of its contributing sources. Poultry is one of the most widespread types of meat consumed worldwide. Poultry flocks are often raised under intensive conditions using large amounts of antimicrobials to prevent and to treat disease, as well as for growth promotion. Antimicrobial r...

Salmonella gallinarum with the biotypes gallinarum and pullorum causes two septicaemic diseases in poultry: fowl typhoid (FT) and pullorum disease. The former Salmonella pullorum serovar is not recognised anymore as such. Both biotypes are differentiated by a few biochemical and molecular tests. Mammals may be infected without showing any illness. In contrast to zoonotic salmonella serovars, Sa...

The pathology of pullorum disease has been frequently described, but little information exists concerning the mechanism by which Salmonella pullorum exerts a damaging effect on its host. While the organism becomes quite generally distributed throughout the chick during the course of disease, the fact that it tends to be prevalent in the liver suggests the possibility of. alterations in both pro...

ABSTRACT. Penelitian ini bertujuan untuk melihat aktivitas antibakteri dari bakteri asam laktat (BAL) yang sudah diisolasi saluran pencernaan itik lokal asal Aceh. Berdasarkan hasil identifikasi gen 16S rRNA menggunakan metode PCR dan Sekuensing diperoleh lima BAL yaitu Lactobacillus plantarum strain C1; Pediococcus acidilactici V2; fermentum Strain D3; I1; S4. mengukur kemampuan terhadap Salmo...
