Abstract: Over the years, Salmonella Heidelberg (SH) has gained prominence in North America poultry production and in the poultry production of other countries. Salmonella Heidelberg has been isolated and reported from poultry and poultry products in Brazil since 1962, whereas Salmonella Enteritidis (SE) has only emerged as a serious problem in poultry and public health since 1993. These strains of Salmonella can cause intestinal problems in newly hatched chicks, and infection may persist until adulthood. Upon slaughter… Show more

“…The qualitative method was preferred to the quantitative method for spleen/liver analysis because many samples with low SH load would be considered negative as a function of the limit of the technique used (quantification only from 100 CFU/g). Normally for SH, the level of contamination in caecum is higher than in spleen/liver (Borsoi et al, 2011).…”

“…Studies examining experimental inoculation of birds have demonstrated that the behaviour of SH resembles that of Salmonella Enteritidis, which can generate bacteria counts in both the intestine (caeca) and the viscera (liver); additionally, the curve to quantify the positivity of the two analysed serotypes was almost identical 72 h after inoculation (Borsoi et al, 2011). For all analysis times, SH counts in the intestines exceeded those in the viscera.…”

“…Lactobacillus bacteria count within the total lactic acid bacterial counts were performed by the microscopic examination of all plate colonies using simple staining. For Salmonella and E. coil determination in samples, 1 mL of the previously prepared dilutions was spread on XLD agar (Borsoi et al, 2011) and Mac-Conkey agar (Difco) (Jang et al, 2007), respectively. Colonies were counted after aerobic incubation at 37°C for 48 h. The results were expressed as CFU per gram of Asian J.…”

“…However, it is important to emphasize that the serotypes evaluated in the studies of Pickler et al (2013) and Santiago et al (2014) were Enteritidis and Typhimurium, respectively, differently from the present study. Furthermore, according to Borsoi et al (2011), broilers challenged with Salmonella Heidelberg excrete less bacteria than those challenged with Salmonella Enteritidis. In addition, they present intermittent excretion of Salmonella Heidelberg (Borsoi, 2009), which may limit the efficiency of cloacal swabs as a diagnostic method …”
