Megjegyzések:	In 2024, a highly fatal outbreak of equine salmonellosis occurred in a Hungarian equine referral hospital, resulting in the death or euthanasia of four out of five affected horses. Salmonella (S.) enterica subsp. enterica serovar Typhimurium was identified as the primary causative agent from equine faecal, reflux, and post-mortem intestinal content samples, while one case involved S. Coeln. Extensive environmental sampling during the outbreak also yielded multiple Salmonella serovars. Whole-genome sequencing revealed a high degree of genetic relatedness among the S. Typhimurium isolates, confirming nosocomial transmission. The source of the isolated S. Typhimurium was most likely a 3-year-old gelding imported immediately before the admission to the hospital. The isolates belonged to sequence type ST376 and exhibited multidrug resistance, including extended-spectrum ?-lactamase and fluoroquinolone resistance genes. Retrospective analysis of microbiological records from 2010 to mid-2024 identified 23 Salmonella-positive equine cases involving eight serovars and three probable nosocomial clusters preceding the 2024 outbreak. Following the outbreak, enhanced passive surveillance was implemented between October 2024 and August 2025. During this period, 56 at-risk horses were examined using selective bacteriological testing of clinical and post-mortem samples, of which 11 (19.6%) were Salmonella-positive, representing eight different serovars. A distinct cluster of S. Martonos was detected, and six of the surveillance-associated cases resulted in fatal outcomes. These findings demonstrate that Salmonella is repeatedly introduced into the equine hospital environment and that serovars differ markedly in virulence and transmission dynamics. The exceptionally high case fatality observed during the 2024 outbreak underscores the importance of integrated genomic surveillance, rapid diagnostics, and sustained infection control measures to mitigate the risk of severe nosocomial salmonellosis in equine clinics.

Cím:	Shifts in sex-specific immune gene expression in a beetle with parental care / Nikoletta A. Nagy, José O. Valdebenito, Johanna Lévai-Kiss, Zoltán Rádai, András Kosztolányi, Tamás Székely, Zoltán Barta

Megjegyzések:	Males and females generally differ in resource investment strategies in order to maximise reproductive output. These strategies involve the control of important systemic processes such as self-maintenance and immune activity, which in turn could be traded-off against aspects of reproduction in a sex-specific manner. While some aspects of this immunomodulation have been previously shown in domestic animals, sex-specific immune modulation using repeated sampling over the breeding period has rarely been tested in the wild. Here we used Lethrus apterus, a sexually dimorphic beetle with parental care, to investigate the association between sex roles (e.g. offspring provisioning) and sex-specific immune gene expression. By determining the immune gene activation of males and females at five successive moments within the active season, we found that their sex-specific immune gene expression varies substantially across the active season, alternating between male bias to female bias and vice versa. Though, when pooling all sampling dates together, there was no overall difference in the number of upregulated immune genes between the sexes. Sex roles in this beetle are associated with energetically demanding behaviours that could potentially explain our results. We highlight the importance of successive sampling protocols to understand ecological dynamics in the wild.

Cím:	The updated genome of the Hungarian population of Aedes koreicus / Nikoletta Andrea Nagy, Gábor Endre Tóth, Kornélia Kurucz, Gábor Kemenesi, Levente Laczkó
Dátum:	2024
ISSN:	2045-2322
Megjegyzések:	Vector-borne diseases pose a potential risk to human and animal welfare, and understanding their spread requires genomic resources. The mosquito Aedes koreicus is an emerging vector that has been introduced into Europe more than 15 years ago but only a low quality, fragmented genome was available. In this study, we carried out additional sequencing and assembled and characterized the genome of the species to provide a background for understanding its evolution and biology. The updated genome was 1.1Gbp long and consisted of 6099 contigs with an N50 value of 329,610 bp and a BUSCO score of 84%. We identifed 22,580 genes that could be functionally annotated and paid particular attention to the identifcation of potential insecticide resistance genes. The assessment of the orthology of the genes indicates a high turnover at the terminal branches of the species tree of mosquitoes with complete genomes, which could contribute to the adaptation and evolutionary success of the species. These results could form the basis for numerous downstream analyzes to develop targets for the control of mosquito populations.
