Summary: The availability of soil phosphorus can affect plant growth, root-soil interactions, and rhizosphere microbial community composition. This study investigated the rhizosphere microbial communities of 24 species of eucalypts under low or sufficient soil phosphorus availability. It was found that eucalypt species identity was the main factor determining the composition of the rhizosphere microbial community, while the effect of phosphorus availability varied among species.

Summary: This study provides high-resolution digital pictures and molecular data of male and female I. rugicollis for the first time, and morphological comparison with I. cornutus could not resolve uncertainties in the latter species' validity. Further molecular comparisons with new specimens of I. cornutus are needed to confirm its status. This study represents the first comprehensive molecular phylogenetic analysis of western Palearctic Pholeoixodes species, including I. rugicollis, and confirms the phylogenetic position of the subgenus Eschatocephalus within Pholeoixodes.

Summary: This study examined the prevalence of Entamoeba infections in wild rhesus macaques in Myanmar, finding high rates of E. nuttalli but no infections of E. histolytica or E. moshkovskii. Genetic analysis revealed that E. nuttalli strains from Myanmar are closer to strains from macaques in China rather than those from macaques in Nepal.

Summary: Wild deer populations in Australia have grown significantly, posing a biosecurity risk to the livestock industry. This study investigated the presence of the intestinal parasite Entamoeba bovis in wild deer and domestic cattle in south-eastern Australia. The study found high prevalence of E. bovis in both cattle and wild deer, and identified new variants of Entamoeba in different deer species. Cross-species transmission of E. bovis between wild deer and cattle has not yet occurred in Australia. Continued surveillance and epidemiological investigations are needed to understand the emergence and transmission of Entamoeba parasites to livestock.

Summary: This study examines the relationship between microbial community dynamics and DMS concentrations in an oceanographic time series conducted on the east Australian coast. The results show that seasonal shifts in microbial community composition affect the net DMSP concentrations, with certain phytoplankton species producing more DMSP than others. Additionally, planktonic bacteria play a significant role in producing DMSP and DMSO in ocean surface waters.

Summary: This study investigated the genetic diversity of Trichomonas gallinae, a protozoan parasite, in bird populations in southeastern Europe. The results showed that this parasite is widely distributed among pigeons and doves, particularly in racing pigeons. Interestingly, the study found that high infection rates were not associated with clinical symptoms. These findings highlight the importance of conducting epidemiological monitoring in trading-breeding places of pigeons.

Summary: This study reports the occurrence of tick-borne protozoan parasites in ticks and tissues of wild cats, mustelids, and red squirrels in Hungary. Several new genotypes of Hepatozoon and Cytauxzoon species were identified, including a new genotype of Hepatozoon fells in wild cats. New tick-host associations were also observed. The study suggests that H. fells and H. mortis can survive transstadially in different tick species.

Summary: The microbial communities in the hydrothermal steam environment of Sasso Pisano exhibit high metabolic diversity, with a higher capability to utilize methane and aromatic compounds, as well as a more diverse sulfur and nitrogen metabolism compared to mesophilic soil microbes. Additionally, heavy metal resistance genes are more abundant in the hot spring microbiome, while the eukaryotic diversity at a fumarole suggests a simplified food web in an extremely nutrient-deprived acidic environment.

Summary: In contrast to most hypotrich ciliates that inhabit the benthos, only a few species of the genus Hypotrichidium have adapted to a planktonic lifestyle. This study investigates the interphase morphology and ontogenetic process of Hypotrichidium tisiae, redefining its ciliary pattern. The morphogenetic features and phylogenetic analyses support the assignment of Hypotrichidium to the family Spirofilidae within Postoralida, as well as the establishment of separate families for slender tubicolous spirofilids and highly helical spirofilids.

Summary: This study provides the first detailed description of the seasonal patterns in bacterial community composition (BCC) in shelf waters off the Ria de Vigo (Spain). The study also reveals strong correlations between BCC and small-sized eukaryotic community composition (ECC), suggesting the importance of biotic interactions in structuring the microbial plankton in this productive area.

Genetic variation of B. gibsoni population was examined to understand disease transmission and develop control strategies. Results showed high genetic diversity within populations and significant differentiation across continents.

Summary: The analysis of table olives microbiome using next-generation sequencing has provided valuable information about the microbial community composition of this popular fermented food. This study used 16S and 18S rRNA sequencing to evaluate the microbial communities of table olives from five Greek popular cultivars, fermented by Greek or Spanish style. The results showed that different curing and fermentation methods had an impact on the microbial composition and biochemical properties of the olives.

Summary: This study investigated the community structure of mycoplankton and their response to environmental changes in the Dafengjiang River estuary in the Beibu Gulf, Guangxi during summer and winter. The study found significant seasonal differences in the alpha-diversity of the mycoplanktonic community and identified key environmental factors that regulate the community structure. The findings provide important insights for ecological environmental monitoring and resource management in the Beibu Gulf.

Summary: The study found that E. histolytica and/or E. dispar were prevalent among school-aged children in three rural schools in the Thai-Myanmar border region of northwest Thailand. Transmission of these Entamoeba species was suggested to occur within classrooms and at home, possibly through person-to-person contact.

Summary: In this study, the proteomic changes in host cells incubated with E. histolytica trophozoites or stimulated by purified native Igl protein were analyzed. The results showed that central carbon metabolism of host cells was suppressed in both E. histolytica-treated and Igl-treated groups, with evidence of decreased expression levels of key enzymes. Additionally, Igl had potential physical interactions with central carbon metabolism enzymes and proteasome subunit alpha and beta, suggesting a role in the degradation of key enzymes.

Summary: The protein Igl1 of Entamoeba histolytica has been found to exhibit hemolytic and cytotoxic activities. The amino acid regions 787-846, 968-1028, and 1029-1088 of Igl1 are responsible for these activities. This is the first report of a protozoan protein with hemolytic and cytotoxic activities in multiple domains.
