TLDR
Serovar diversity was found to serogroup O:7 that accounted for 22 different types, followed by serogroups O:4, O:3,10 and O:9 with 19, 15 and 10 serotypes respectively, which were the most frequent serovars over the 30 years.Abstract:
Salmonella strains were isolated from ill and shedding birds in several regions of Brazil between 1962 and 1991. Serotyping of 2123 isolates showed 90 serovars pertaining to 14 serogroups. There was a predominance of groups O:9 (40.0%), O:4 (33.3%), O:7 (10.6%) and O:3,10 (6.7%). Major serovar diversity was found to serogroup O:7 that accounted for 22 different types, followed by serogroups O:4, O:3,10 and O:9 with 19, 15 and 10 serotypes respectively. An average of 10.8 serovars was isolated per year. S. Gallinarum, S. Pullorum, S. Typhimurium, S. Heidelberg, S. Enteritidis and S. Infantis were the most frequent serovars found over the 30 years, representing 65% to 67% of the total of isolates. Bacteriological and epidemiological aspects concerning a number of serotypes are discussed.read more

TL;DR: PCR-RV method is diagnostic of Salmonella at the genus level and ST at the serovar level, although other tests are needed to identify SE, SG and SP to serovars level.

Antimicrobial resistance in Salmonella enteritidis strains isolated from broiler carcasses, food, human and poultry-related samples
Sílvia Dias de Oliveira,Fabiana da Siqueira Flores,Luciana Ruschel dos Santos,Adriano Brandelli +3 more
TL;DR: The high number of antimicrobial resistant S. enteritidis found in Southern Brazil indicates the need for the prudent drugs uses to diminish the development and spread of antimacterial resistance.

Salmonella Enteritidis em Aves: Retrospectiva no Brasil
TL;DR: The latest surveys carried out in 2001 continue showing the presence of SE in poultry materials as the main serovar responsible for human food infections, although chicken carcasses show high levels of contamination by SE, it is eggs and egg products which are the products mostly responsible for outbreaks in humans.

Salmonella spp investigation in transport boxes of day-old birds
TL;DR: The presence of Salmonella was investigated in transport boxes of newly hatched chicks in the moment they were received in the farms, finding that S. Heidelberg and S. Mbandaka were simultaneously detected in one broiler breeder farm.

TL;DR: Over the past 5 years Salmonella enteritidis infections in humans have increased on both sides of the Atlantic ocean, and investigations in individual countries suggest it is related to consumption of eggs and poultry which harbour the organism.

Influence of Resident Salmonella on Contamination of Broiler Flocks
TL;DR: An epidemiological survey was made of 5329 samples from 10 poultry operations and the most important source of contamination was determined to be the resident Salmonella of the flock i.e., the strain isolated on chicks' first day in the poultry house.
