Summary: Crustacean amphipods, serving as intermediate hosts for parasites, also act as sensitive indicators of environmental pollution in aquatic ecosystems. This study investigated the infections of Gammarus roeselii with two species of Acanthocephala - Pomphorhynchus laevis and Polymorphus minutus - in different pollution levels of the Rhine-Main metropolitan region. Higher prevalence and intensities of P. laevis were found at downstream sites close to a large wastewater treatment plant. The study also examined the sensitivity of infected and uninfected amphipods towards the insecticide deltamethrin, revealing an infection-dependent difference in sensitivity. The results suggested a beneficial effect of acanthocephalan infection for G. roeselii at polluted sites.

Summary: This study examined the contamination level of PFAS in the fish fauna of the Po River in Italy and found that perfluorooctane sulfonate (PFOS) was the most prevalent PFAS. The concentrations of other PFAS were significantly higher in the pelagic bleak compared to the benthic channel catfish. The accumulation of PFAS in fish was not significantly affected by parasitic infection.

Summary: This study provides insights into how temperature influences movements of gammarid species in the stream. Elevated temperature did not affect the intensity of P. laevis manipulation in G. pulex as intermediate host.

Summary: Alterations in host phenotype induced by metazoan parasites are influenced by the composition of symbiotic microbial communities living within individual parasites. Microbiome composition variation among individual parasites can explain the variation in the extent of alterations to host phenotype. Two approaches are proposed to further understand the impact of microbiome composition on host-parasite interactions.

Summary: This article extensively reviews the current knowledge of phenotypic alterations in amphibians following parasite infection. The results show that parasites can manipulate amphibian behaviors, modify limb morphology and impair locomotor activity, and alter host physiology to increase their transmission and survival. Moreover, human-induced changes in environmental conditions are the most significant factors affecting parasite exposure and susceptibility.

Summary: Gonococcus, the bacterium responsible for gonorrhoea, has been infecting humans since ancient times. The global prevalence of gonorrhoea is currently increasing at an alarming rate, along with the rise of antimicrobial-resistant strains. This bacterium has evolved various mechanisms to manipulate the host and evade immune responses, which contribute to its ability to colonize and infect different host tissues. Understanding these mechanisms is crucial for combating this pathogen.

Summary: Cell death, including necroptosis and pyroptosis, is an important part of the antiviral immune response, eliminating virus-infected cells and promoting immune development through the release of inflammatory mediators. Viruses employ evasion mechanisms to suppress these cell death pathways and antagonize host immunity.

Summary: Anthropogenic interference has caused significant ecological changes in freshwater ecosystems. Pollution and the introduction of new species have altered the community structures of macrozoobenthos and their parasite communities. The Weser river system has experienced a decline in biodiversity due to salinization caused by local industry, but the introduction of the North American amphipod Gammarus tigrinus has led to the presence of the acanthocephalan parasite Paratenuisentis ambiguus in the Weser. This study investigates the recent changes in the acanthocephalan parasite community and reveals shifts in distribution and host usage, contributing to the perplexing taxonomy of the genus Pomphorhynchus in the era of ecological globalization.

Summary: This study aimed to close the gap in knowledge about the helminth community of mallards in Austria by analyzing parasites from 60 birds shot by hunters. The results showed a particularly low diversity of helminths in the Austrian mallard population, especially in terms of cestodes and nematodes. The distribution of parasite intensity followed a typical pattern, with most birds being lightly parasitized or uninfected.

Summary: Traditional bulk isotopic analysis is limited in describing parasite-host relationships in food webs, while compound-specific stable isotopes from amino acids offer a promising novel approach for mapping these interactions. The compound-specific method provided clearer trophic discrimination factors and accurately identified parasitic trophic interactions, highlighting its usefulness in clarifying feeding strategies for parasitic species within marine food webs. Despite the limitation of applying a universal trophic discrimination factor, compound-specific stable isotope analysis remains a valuable tool to increase understanding of parasitic interactions.

Summary: The study confirmed that parasitic worms with longer life cycles infect a greater diversity of host species, with middle life stages showing the highest level of generalism. Generalism comes with costs, and it is determined by both ecological opportunity and life-history trade-offs. There is no trade-off in generalism from one stage to the next, but parasites spend less time growing and developing in stages where they infect more taxonomically diverse hosts.

Summary: This article provides a detailed method for genetic manipulation of Acanthamoeba castellanii and the giant viruses it hosts using CRISPR-Cas9 or homologous recombination. It allows the study of gene function in giant viruses and the interactions between pathogens and the host organism A.castellanii.

Summary: The environmental context can lead to diverse phenotypes from identical genotypes. The concepts of epigenotypes and extended phenotypes are proposed to explain the relationship between genetic information and the environment. Epigenotypes suggest that modifications of genetic material can generate nonvariant modules of development, while extended phenotypes propose that the appropriate phenotype of genetic information can extend beyond the organism itself. A synthesis between epigenotypes and extended phenotypes, called extended epiphenotypes, is proposed in this perspective.

Summary: The study focused on the anesthetic effects of MS-222 and Eugenol in the freshwater amphipod Gammarus pulex, demonstrating the sedative and analgesic-like effects of MS-222, with Eugenol requiring a higher concentration for similar efficacy. Additionally, a new semi-automated electric shock device was used to induce nociception, offering a standardized and flexible protocol for studying nociceptive response and anesthesia in aquatic organisms.
