“…Pseudomonas spp. breakpoints were adopted from CLSI (CLSI, 2015) for colistin, as no Enterobacterales criteria for disc diffusion antibiotic-resistance assay has been defined either by CLSI or the European Committee on Antimicrobial Susceptibility Testing (EUCAST), as it was proposed by Bueno et al (Bueno et al, 2024).…”

We studied the serovars present and the performance of two selective plating media, Hektoen enteric agar (HE) and Xylose-Lysine-Desoxycholate (XLD) agar, as well as the time of tetrathionate broth incubation (one and five days) used for Salmonella isolation in different samples of egg and egg packs collected from supermarkets in Argentina. We also determined the occurrence of bacterial growth inhibitors in egg content and the antibiotic resistance profile of the isolated strains. Salmonella spp. was detected in 29 samples (1.8%) from 1,643 different types of egg and egg pack samples analyzed. Eight serovars of Salmonella were isolated: S. ser. Typhimurium (ST), S. ser. Enteritidis (SE), S. ser. Agona, S. ser. Westhampton, S. ser. Brandenburg, S. ser. Gallinarum (biovar Gallinarum), S. ser. Muenchen, and S. ser. Montevideo. The most frequent were ST and SE; both were present in eggshells, yolk, and albumen. The increase in the incubation time in tetrathionate broth affected the isolation of Salmonella spp. from eggshell and pool of yolk and albumen with different values of relative sensitivity and accuracy (p<0.05). Furthermore, there was a significant difference between the two-plating media at the time of tetrathionate broth incubation in eggshell for the relative sensitivity (p<0.05). The agreement between XLD and HE agar in relation to the time of tetrathionate broth incubation depended on the type of samples studied. The occurrence of bacterial growth inhibitors in yolk and albumen depended on bacteria assayed. However, these were presented in yolk and albumen from the same pool of egg content. There were 2 and 8 different patterns of resistance among Salmonella strains isolated, and 87% of these strains were multidrug-resistant. It is necessary to understand the epidemiology of Salmonella from eggs and to alert public health to minimize the prevalence of antibiotic resistance of Salmonella spp. in Argentina.

The occurrence of esophagitis and ingluvitis caused by Salmonella Typhimurium in passerines seized from illegal wildlife trafficking is described. This illegal activity causes stress and leads to lowered immunity in the birds. Additionally, inadequate hygiene conditions predispose the birds to diseases such as salmonellosis. Few studies report the occurrence of Salmonella-induced lesions in the esophagus and crop of passerines; therefore, this study aimed to describe the disease in birds of the genus Sporophila, as well as to investigate the presence of the bacterium in the environment and determine the antimicrobial resistance profile of the isolated bacteria. Three birds of the genus Sporophila were necropsied. In the esophagus and crop, yellowish plaques corresponding to necrosis with bacterial aggregates were observed. Salmonella spp. was isolated from these lesions, with genus confirmation via MALDI-TOF mass spectrometry. Environmental samples were collected from the enclosures and cages where the animals were quarantined, and the same bacterium was isolated. In two birds, the serotype S. Typhimurium was identified. Antibiograms performed on the strains from the birds and the environment revealed resistance to antibiotics in the classes of penicillins, sulfonamides, aminoglycosides, monobactams, tetracyclines, and first and third-generation cephalosporins. To the authors’ knowledge, this is the first report of this agent causing death in Sporophila due to esophagitis and ingluvitis. It is also the first report of salmonellosis in three species of passerines in Brazil. The study underscores the importance of understanding the pathogens circulating in wild animals, especially within the context of One Health.
