Summary: The use of environmental DNA (eDNA) technology to monitor parasites in fish farms revealed positive associations between rainfall and temperature with the abundance of Cryptocaryon irritans, a ciliate parasite. Additionally, the bacterial genus Coraliomargarita showed a significant negative relationship with the parasite abundance in water, indicating its potential role in controlling ciliate parasites in marine fish farms.

Summary: Parasites play important roles in ecosystems by changing the behavior and population dynamics of their host species and the shape of entire communities. Although birds are well-studied, the infection patterns of endoparasites at the community level are not fully understood.

Summary: Parasites play a crucial role in biodiversity, and understanding their relationship with hosts is essential for monitoring ecosystem changes. A study on metazoan parasites in Hemiodus unimaculatus from the jar' River in Brazil found a diverse parasite community with an aggregate dispersion pattern.

Summary: This study investigates the potential use of the parasitic isopod C. tetrodontis and its fish host A. honckenii for marine bioaccumulation monitoring. The results show significant differences in the concentrations of nickel and copper between two sampling sites on the South African temperate south coast. Compared to fish hosts, the parasitic isopods accumulate higher levels of all elements except cadmium. Therefore, C. tetrodontis can be defined as a good bioindicator for elements such as cadmium, copper, manganese, nickel, lead, selenium, and zinc.

Summary: In this study, we used the Asian water monitor lizard as a model species to explore the physiological implications of living in a highly anthropogenic landscape and the consequences of dietary shifts on parasite community. Our findings showed that dietary diversity affects the metabolism of monitor lizards and the composition of their parasite communities.

Summary: Parasites play important roles in ecosystems, but their complex interactions and roles remain poorly understood. This study in Sabah, Malaysian Borneo, found that parasite communities differ between nocturnal and diurnal primates, with soil-transmitted helminths being widespread. The findings provide new insights into parasite diversity in primate communities and highlight the need for further research in Asia and beyond.

Summary: During a parasitological survey, a new species of Hedruris genus was discovered in the stomach of Synbranchus marmoratus Bloch from the Parana Guazu River, Parana River basin in Argentina. The new species, Hedruris anguila sp. nov., is morphologically distinct from other Hedruris species. This is the first time that a member of the family Hedruridae has been found parasitizing a species of Synbranchidae.

Summary: This study used host-specific parasites as a tool to investigate the historical biogeographical contacts between freshwater fish from North America and Europe. By analyzing the phylogenetic relationships between specific parasites, the study revealed different origins for the parasites in different regions, suggesting different historical routes of dispersion for the fish. The study also showed that historical contacts between European and North American fish were accompanied by host switching of the parasites. Furthermore, the study found evidence of multiple colonizations of fish species due to ancient paleogeographic events and contemporary drainage reorganization. The use of host-specific parasites as a supplementary tool provides valuable insights into the biogeography of fish populations.

Summary: The impacts of pollutants on the aquatic environment have been a growing concern in recent decades. This study investigated the uptake of pharmaceutical compounds in common carp and the response of parasite communities to environmental changes caused by organic pollution. The results showed higher pollutant uptake and changes in fish biometric parameters and parasite load in the treatment group. These findings emphasize the importance of detailed taxonomic analyses when using parasites as bioindicators in environmental studies.

Summary: This study evaluated the diversity of Chytridiomycota in phytoplankton communities in the NW Mediterranean Sea and demonstrated their interactions with their hosts. The relative abundance of Chytrids was highest in samples dominated by dinoflagellates, indicating the presence of specific chytrid communities. The study also identified and described three species of Chytridiomycota, including one of the most abundant environmental sequences and two previously undescribed species.

Summary: In this study, the effects of a DMY-Zn complex on the intestinal microbiome composition and liver biological function of two marine fish species were investigated using high-throughput sequencing technology. The results showed that DMY-Zn improved the anti-oxidative ability of both fish species and had positive impacts on intestine health and carbohydrate utilization in the golden pompano, while significantly enriching unclassified bacteria in the grouper. The responses of intestine microbiome and liver metabolism to DMY-Zn differed, possibly due to their different Zn basal requirements.

Summary: This study investigated the impact of temperature changes on Tetrasphaera-PAOs and found that at lower temperatures their bioactivity was inhibited, while at higher temperatures the efficiency was very high. Temperature variation can affect the distribution of Tetrasphaera clades, which may be a main reason for EBPR performance.

Summary: A checklist of parasitic cymothoids from Malaysian waters is provided based on available literature and materials collected from 2010 to 2020. The checklist includes 19 species in ten genera, with seven new records from Malaysia and eight new host records. The study reveals that the cymothoid-host association in Malaysian waters primarily occurs in families such as Carangidae, Engraulidae, and Leiognathidae.
