Summary: Avian haemosporidian parasites in Texas, specifically Haemoproteus, Leucocytozoon, and Plasmodium, have been relatively understudied despite the large geographic area and diverse ecoregions. This study conducted in south Texas found different infection patterns and parasite community composition between adjacent ecoregions. The findings provide important insights into the prevalence and disease ecology of avian malaria in this area.

Summary: This study investigates the development patterns and impact on hosts of two species of avian parasites, Haemoproteus dumbbellus and Haemoproteus hirundinis. The authors found that H. dumbbellus develops in multiple organs, while H. hirundinis is only found in the pectoral muscles. These findings suggest a potential phylogenetic influence on the development of Haemoproteus parasites.

Summary: Biting midges, as small insects that feed on various hosts, have been found to potentially carry harmful pathogens such as Leishmania and Trypanosoma. This study collected biting midges in a leishmaniasis-endemic area in Thailand and found that they had a diversified feeding habit, feeding on cows, dogs, pigs, and avians. The study also detected the presence of avian haemosporidian parasites in the collected midges. Further research is needed to determine if these biting midges can act as natural vectors for trypanosomatid parasites.

Summary: The study evaluates the effects of bird community on avian haemosporidians infections in a Neotropical region. The findings show that bird community dominance and richness do not significantly affect the prevalence and number of avian parasite infections, but they are related to the total number and expected richness of parasite lineages. This study contributes significantly to our understanding of blood parasite diversity in tropical birds within a relatively understudied region of South America.

Summary: This study found that the effective diversity for both birds and parasite lineages was higher in the Amazon basin ecoregions. Additionally, it was also shown that ecoregions with greater diversity of bird species also had high parasite richness, suggesting the importance of host community in explaining parasite richness. Generalist parasites were found in ecoregions with lower bird diversity, which implies that the abundance and richness of hosts may influence the exploitation strategy followed by haemosporidian parasites.

Summary: This study investigated the effects of haemosporidian blood parasites on bird migration. The results showed that parasite infection did not have a significant effect on the body condition of the birds, but infected juveniles arrived later than non-infected individuals. The impacts of distinct parasite lineages on bird condition during migration may vary.

Summary: In this study, molecular genetics were used to detect and characterize vector-borne pathogens in hippoboscid flies infesting domestic and wild animals in Austria. Several pathogens were found, including some with zoonotic potential. The presence of Trypanosoma sp. in H. equina, a louse fly, was also reported for the first time in Austria. Further research and monitoring are needed to understand the role of these ectoparasites as vectors of infectious agents in a One-Health context.

Summary: This study found a 12.5% prevalence of louse flies on raptors in Canada, representing four species with some new distribution records. The research suggests that the host species and the migration month may influence the presence of louse flies. Further study of louse flies is needed to better understand their prevalence across different bird groups and geographic distribution.

Summary: Human and animal pathogens transmitted by arthropods, such as ticks and mosquitoes, are a global concern. Control measures using acaricides are threatened by resistance in vector populations. Alternative strategies that target the vector microbiota and interfere with pathogen development are encouraged. Understanding the immune functions of host antibodies and disrupting the vector microbiota open up possibilities for novel transmission-blocking vaccines.

Summary: We described a new Leucocytozoon species, Leucocytozoon polynuclearisn. sp., found in two North American woodpeckers. This study analyzed the morphology of the parasite in its blood stages and a portion of its mitochondrial cytochrome b gene. The distinctive features of L. polynuclearisn. sp. include triangular-shaped host cell nuclei and the position of host cell nuclei above the gametocytes. Phylogenetic analysis showed that L. polynuclearisn. sp. is more closely related to other North American Leucocytozoon species than to the only other Leucocytozoon species found in Picidae birds, Leucocytozoon squamatus Nandi, 1986. The distribution data suggests that L. polynuclearisn. sp. infects woodpeckers throughout North America, while L. squamatus is restricted to Old World Piciformes birds.

Summary: This paper proposes the hypothesis that gut microbiota diversity shapes the immune response and resistance to avian malaria. The authors also suggest that anti-alpha-Gal antibodies are transmitted from mother to eggs for early malaria protection in chicks. They provide preliminary data showing the presence of bacterial alpha 1,3GT genes in the gut microbiome of birds and the induction of anti-alpha-Gal antibodies upon avian malaria infection.

Summary: In this study, researchers found that anti-microbiota vaccines targeting Enterobacteriaceae within mosquito midguts can modulate the mosquito microbiota and significantly disrupt the development of Plasmodium relictum in its natural vector Culex quinquefasciatus. These findings suggest that anti-microbiota vaccines can be a novel tool to control malaria transmission and potentially other vector-borne pathogens.

Summary: Avian malaria infection does not significantly change the alpha and beta diversity of the bird gut microbiome, but it does alter the composition and abundance of certain bacterial taxa. The progression of microbiome structural states differs between infected and uninfected birds. Infection by avian malaria parasites is associated with the presence of specific metabolic pathways and the abundance of these pathways changes over the course of infection.

Summary: Research has found that infection with Borrelia afzelii causes changes to the microbiota composition, diversity, and structure in ticks. Anti-microbiota vaccines can alter the tick microbiota's ability to be infected by Borrelia and decrease the pathogen's load. Network analysis is a suitable tool for identifying properties of the vector microbiota associated with infection-refractory states.
