Summary: Gene flow can increase additive genetic variation and introduce beneficial alleles, facilitating adaptation. However, it can also impede adaptation by disrupting genotypes, introducing harmful alleles, and creating negative interactions. This study found that gene flow increased parasite resistance in nematodes and that gene flow from adapted populations resulted in greater resistance increases, especially from novel genetic backgrounds. These findings demonstrate the importance of gene flow in adaptation and highlight the influence of source population characteristics.

Summary: This study compared the susceptibility of Clostridium perfringens to the non-medically important antibiotic avilamycin before and after its approval in Canada. The results showed that there was no impact on the susceptibility of C. perfringens to avilamycin after 7 years of its continued use. Furthermore, avilamycin poses no risk to human health in terms of cross-resistance or co-selection of other medically important antibiotics.

Summary: Endoparasitism is a common disease in dogs despite the availability of diagnostic tests and treatments. The consequences of this disease in seemingly healthy dogs are largely unknown. A study on young dogs found that parasite-positive dogs had lower levels of certain blood components and were more likely to be from rural areas.

Summary: Nematodes have lost the ability to produce necessary lipids and have evolved the capacity to acquire them from diet or host animals. The FAR family of proteins facilitates lipid acquisition and could be a potential target against roundworms. However, their roles in nematodes are not well understood.

Summary: In this study, two DEV recombinants expressing DHAV-3 genes were generated using a fosmid-based rescue system. These recombinant viruses expressed DHAV-3 genes well in infected chicken embryo fibroblasts, induced neutralizing antibodies in ducks, and showed solid protection against lethal DEV challenge and DHAV-3 infection as early as 7 days post-vaccination, demonstrating the potential for bivalent vaccine applications.

Summary: A microsporidian infection was reported for the first time in laboratory-reared larvae of the damselfly Ischnura elegans, with distorted wing development and mortality observed in infected individuals. Factors such as higher rearing temperatures and predator cues from invasive alien signal crayfish may contribute to increased infection rates and negative fitness consequences.

Summary: This study focused on the hospitalized children and adults during a large waterborne outbreak of Campylobacter jejuni in Askoy, Norway in 2019, providing insights into demographics, comorbidities, clinical features, treatment and complications. Children were mostly under 4 years old, while adults had more comorbidities.

Summary: Coordinated singing, performed by mated pairs and sometimes joined by offspring, is a distinctive behavior of Neotropical titi monkeys. The function of these duets and choruses, associated with mate or territorial defense, is not yet fully understood. This study examined the patterns of coordinated singing in wild groups of coppery titi monkeys in the Peruvian Amazon. The results suggest that these songs may serve a function in joint resource defense and inter-group communication, but not in mate defense.

Summary: Intensification of agriculture leads to increased pesticide use and transformation to large-scale monocultures, which significantly affects populations of non-target arthropods. The ground beetle Poecilus cupreus from landscapes dominated by large fields showed reduced sensitivity to the commonly used insecticides, indicating the evolution of resistance. However, no increased resistance was found in beetles from more heterogeneous landscapes dominated by small fields.

Summary: The present study aimed to investigate the pathogenesis of DSS-induced enteritis in Orange-spotted grouper (Epinephelus coioides). Fish were challenged with 200 μl 3% DSS via oral irrigation and feeding, using an appropriate dosage based on the disease activity index. The results showed that DSS-induced inflammatory responses were closely associated with the expression of pro-inflammatory cytokines, NF-kappa B, and myeloperoxidase (MPO) activity. Histological examination and SEM analysis revealed severe intestinal lesions, inflammatory cell infiltration, and microvillus effacement. The injured intestinal villi gradually recovered during the experimental period of 18 days. These findings provide valuable insights into the pathogenesis of enteritis in farmed fish, contributing to the control of enteritis in aquaculture.

Summary: Clostridioides difficile infection (CDI) is the leading cause of nosocomial diarrhea and pseudomembranous colitis in the USA. This study investigates the role of two protein toxins, TcdA and TcdB, produced by the pathogen in causing disease. The study finds that both toxins have an additive role in disease pathogenesis and produce both glucosyltransferase-dependent and independent phenotypes. These findings will contribute to the development of toxin-based therapeutics for CDI.

Summary: The aim of this study was to assess the efficacy of alternative substances, including b-glucans, MOS, essential oil, and probiotics, as replacements for anticoccidial agents. The results showed that the use of additives had superior effects on performance parameters compared to the application of anticoccidial agents throughout the entire experiment. The inclusion of additives significantly improved performance parameters in broilers challenged with coccidia and Clostridium perfringens at 14 days of age, as well as with C. perfringens at 21 days of age.

Summary: Eosinophilic enteritis (EE) is an immune-mediated disease characterized by extensive eosinophilic infiltrates in the intestinal mucosa. Monitoring dynamic changes in eosinophil count and prompt treatment are crucial for EE patients.

Summary: Fungi play a crucial role in shaping the diversity of life. This study investigates the genomic and metabolomic diversity of Escovopsis, a specialized parasite of fungus-growing ant gardens. The research reveals that Escovopsis evolved unique genomic repertoires to specialize in the symbiotic relationship between fungus-growing ants and microbes. Genome reduction, particularly in coding regions, was a consistent feature across the genus Escovopsis. Biosynthetic gene clusters contribute to phylogenetic differences among Escovopsis species and their sister taxa.

Summary: This study examines the predictors of affiliation in coppery titi monkeys, such as temperament, age at pairing, pregnancy status, and presence of an infant. The results show that pregnancy predicts higher levels of affiliation, while the presence of an infant and aggression do not predict variability in affiliation. The role of age in affiliation remains inconclusive.
