Summary: In this study, a strain of Weissellosis agent bacterium was isolated from diseased rainbow trout in Brazil, and its whole genome sequence was compared with strains from diseased rainbow trout in Mexico and beaked whales. The results showed low similarity between the Mexican and Brazillian strains, as well as low similarity between fish isolates and the Weissella ceti type strain. Furthermore, phenotypic assays revealed differences in hydrolysis abilities and growth characteristics. Based on these findings, a novel species named Weissella tructae sp. nov. is proposed for the Weissella strains isolated from rainbow trout.

Summary: A study on the genetic diversity and population structure of Gray's beaked whales in the Southern Hemisphere found high levels of mtDNA diversity, stable demographic history, and no geographic structure. An increase in female effective population size approximately 250 thousand years ago coincided with enhanced Southern Ocean productivity, sea surface temperature, and potential habitat expansion. These findings suggest that Gray's beaked whales are resilient to future ecosystem changes.

Summary: This study characterized 170 P. multocida isolates from 125 BRD outbreaks using different typing approaches. The results revealed a very low genetic diversity among P. multocida, with most isolates belonging to the A:L3 genotype. Furthermore, the results of MLST and PFGE supported the clonal population structure of BRD-associated P. multocida isolates. These findings highlight the genetic relatedness of most P. multocida isolates associated with BRD in cattle.

Summary: The Canary Islands have experienced two volcanic eruptions in the last decade: a submarine eruption in El Hierro in 2011-12, and a subaerial eruption in La Palma in 2021. Necropsies of fish specimens from El Hierro and La Palma revealed pathological findings associated with both eruption styles. During the submarine eruption, high mortality and congestion in various organs were observed in fishes, while fishes near the lava deltas of the subaerial eruption showed increased mortality, ash particles in their gills, and intestinal impaction with volcanic material.

Summary: In contrast to the abundance of research on marine debris, there is a lack of scientific attention on terrestrial anthropogenic litter and its impacts. This study aimed to investigate the potential pathological consequences of ingested litter on the health of domestic ruminants, similar to their relatives in the ocean, cetaceans. The study examined meadows in Northern Bavaria, Germany, and found that all five meadows contained garbage, with plastics being the most dominant litter material. Ingested anthropogenic debris had negative effects on the animals' welfare and productivity.

Summary: This study aims to assess the distribution of CTXs in fish, considering different muscle samples, the liver, and gonads. The results show that the caudal muscle next to the tail is a reliable part for use in determining the toxicity of fish flesh for safe consumption. Additionally, the analysis of the liver and gonads could provide further information on doubtful samples and be used for CTX monitoring in areas with an unknown prevalence of ciguatera.

Summary: Fish exposed to supersaturated water are susceptible to gas embolism, leading to gas bubble disease similar to decompression sickness in mammals. Biomarkers of cell damage, such as the HSP family, ET-1, and ICAM-1, show increased expression in response to gas embolism, making them potential targets for further studies. The GBD model, which involves exposing fish to highly supersaturated water, has been shown to induce severe gas embolism, as confirmed by histopathological examination and gas score method.

Summary: This article describes the presence and characteristics of intracytoplasmic eosinophilic globules (IEGs) in the hepatocytes of cetaceans. The study found that 83% of the analyzed cetaceans exhibited IEGs within their hepatocytes. These globules showed various staining patterns and were positive for fibrinogen, albumin, and alpha 1-antitrypsin. The presence of IEGs was associated with factors such as live-stranding, hepatic congestion, and nutritional status. The proteomic analyses suggested a relationship between IEGs and acute stress, disease, and cellular protective mechanisms.
