Carrier horses may intermittently shed Salmonella, thereby acting as a source of infection for other animals and humans. The aim of this study was to investigate the occurrence and molecular subtyping of Salmonella spp. in horses from Argentina, focusing on potential zoonotic relevance. Only a single isolate (S. Newport) was obtained from fecal samples of 249 clinically healthy horses (2018-2022), indicating a very low carrier detection rate (0.4%). Additionally, 13 isolates from horses with clinical signs of salmonellosis (2006-2017) were analyzed, which comprised S. Typhimurium (n = 9), S. Newport (n = 2), S. Oranienburg (n = 1), and S. Freetown (n = 1). Pulsed-field gel electrophoresis (PFGE) revealed genetic diversity among Salmonella serovars, including clonal outbreaks of S. Typhimurium in a hospital. Comparative analyses using the National PulseNet database demonstrated that many equine isolates shared indistinguishable PFGE patterns with strains from human, bovine, porcine, caprine, and avian origin. Our results suggest the circulation of common Salmonella clones among several unrelated species and highlight that horses may act as potential reservoirs within a One Health framework. The identification of S. Freetown in equines, representing the first report in South America, further emphasizes the need to enhance the surveillance of the pathogen. Despite limitations due to sample size and underdiagnosis in veterinary settings, these findings support the inclusion of equine populations in epidemiological monitoring to improve the management of zoonotic risks associated with Salmonella. 2026-04-01T00:00:00Z http://sgc.anlis.gob.ar/handle/123456789/2742 Title: Analysis of Prevalence and Mortality Among Neonates and Children With Intestinal Atresia: A Multinational Study, 1974-2015 Authors: Carreño, Angie; Aguilera, Maria Paula; Ibañez, Lina; Sarmiento, Karen; Gili, Juan A; Siffel, Csaba; Nembhard, Wendy N; Bergman, Jorieke E H; Bermejo-Sánchez, Eva; Tagliabue, Giovanna; Dastgiri, Saeed; Feldkamp, Marcia L; Pocius, Stephanie; Gatt, Miriam; Martinez, Laura; Canessa, María Aurora; Groisman, Boris; Källén, Karin; Landau, Danielle; Lelong, Nathalie; Morgan, Margery; Arteaga-Vázquez, Jazmín; Santoroi, Michele; Rissmann, Anke; Sipek, Antonin; Szabova, Elena; Wertelecki, Wladimir; Canfield, Mark A; Mastroiacovo, Pierpaolo; Zarante, Ignacio Abstract: Small intestinal atresia (SIA) consists of a congenital obstruction of the lumen of the duodenum, jejunum, or ileum with varying severity. The aim of the investigation was to analyze the prevalence and mortality of SIA, using data from the International Clearinghouse for Birth Defects Surveillance and Research (ICBDSR).

It is the causal agent of avian chlamydiosis and psittacosis in humans and it is globally distributed. Chlamydia psittaci is one of the main zoonotic pathogens transmitted by birds. In Argentina, there has been limited research on the prevalence and genetic variability of C. psittaci. The aim of this study was to detect and genotype C. psittaci using molecular techniques in birds living in Buenos Aires City, Argentina, during the period 2012–2015. A descriptive, observational, retrospective and cross-sectional study was carried out. A total of 983 bird samples submitted for diagnosis of avian chlamydiosis were analyzed. The frequency of C. psittaci was 12.54% and 7.89% in Psittaciformes and Columbiformes, respectively. A 348 bp region of the ompA gene was sequenced in positive samples. Molecular genotyping was performed through a Bayesian phylogenetic analysis. Of the 983 bird samples, 83 were positive for C. psittaci and 44 could be sequenced. The genotypes found were A, B, and E. Despite the high levels of host specificity, we found six psittacids with genotype B and one pigeon with genotype A, reflecting the affiliative interaction between Psittaciformes and Columbiformes. This study represents the first survey reporting the presence of C. psittaci in birds within the largest and most populous city in Argentina. 2024-11-14T00:00:00Z
