To determine the role of 0.5% sodium bicarbonate (NaHCO3) on the performance of chickens inoculated with Salmonella gallinarum, a total of 720 one-day-old-broiler chickens from four strains Hubbard (H), Lohmann (L), Ross (R) and Balady (B) were grown for 42 days in 24 pens, two levels of NaHCO3 (0 and 0.5%) and 3 replicates/treatment (4 strains × 2 dietary treatment × 3 replicates of 30 birds f...

Aflatoxicosis and Salmonella gallinarum exert their effects on the body weight and mortality of chickens without any interaction.

Serovars of Salmonella enterica exhibit different host-specificities where some have broad host-ranges and others, like S. Gallinarum and S. Typhi, are host-specific for poultry and humans, respectively. With the recent availability of whole genome sequences it has been reported that host-specificity coincides with accumulation of pseudogenes, indicating adaptation of host-restricted serovars t...

The poultry red mite (PRM) Dermanyssus gallinae is well known for its vectorial role pathogens, such as Salmonella enterica ser. Gallinarum, the causative agent of fowl typhoid. Here, we ascertained vertical transmission S. Gallinarum across PRM life stages, combining Baudruche-based in vitro feeding system and a PRM-fitting DNA extraction detection method by qPCR. Small-sized pools (4–5 specim...

Chicken peritoneal exudate cells (PEC) were induced by Sephadex G-50 injection and were used for studying their in vitro phagocytic activity towards sheep red blood cells (SRBC) and Salmonella gallinarum. The peritoneal macrophages-were phagocytic to opsonised as well as to non-opsonised SRBC or S. gallinarum. The recognition and phagocytosis depended on time of exposure as well as the intensit...

Administration of probiotic Lactobacillus cultures is an important alternative to the use of antibiotic growth promoters and has been demonstrated to improve animal health, growth performance, and preharvest food safety in poultry production. Whereas gastrointestinal colonization is thought to be critical to their probiotic functionality, factors important to Lactobacillus colonization in chick...

The goal of this study was to compare the effects Bacillus subtilis and antibiotic enrofloxacin on growth performance, immune response, intestinal histomorphometry cecal Salmonella numbers in broilers challenged with S. gallinarum. Salmonella-free chicks (n = 240) were allocated four groups, comprising six replicates 10) each. Group NN not infected received no treatment. SN SE treated enrofloxa...

The study was undertaken to elucidate the recent epidemiological status of salmonellosis in India. A total of 23 Salmonella isolates were recovered from different disease outbreaks in different geographical locations. The phenotypic analysis by serotyping, transmission electron microscopy and antibiogram profiles were able to classify the Salmonella isolates based on different serovars. The S. ...
