Summary: This study investigated the genetic diversity, prevalence, and mechanisms of resistance to quinolone antibiotics in 178 Campylobacter jejuni isolates from humans, cattle, dogs, and chickens in Turkey. The results showed that there were 21 clonal complexes (CCs) and 78 different sequence types (STs) among the isolates, with CC21, CC353, CC206, and CC257 being the predominant clones. Quinolone resistance was detected in 41% of the isolates, and all resistant isolates had a specific mutation in the gyrA gene. The study provided important insights into the transmission pathways of C. jejuni in Turkey, suggesting that broiler meat and dogs may be the most important sources of human campylobacteriosis in the country.

Summary: This study assessed the efficacy of three air samplers (AirPort MD8, BioSampler, and Coriolis Micro) in detecting aerosolized C. burnetii. The results showed that all three devices were able to effectively detect the bacteria. However, at high concentrations, the AirPort performed better than the other two devices in terms of recovery probability. At intermediate and low concentrations, the AirPort detected at a level higher than or similar to that of other samplers. These findings are important for estimating the risk of Q fever transmission from likely sources to nearby communities.

Summary: Fungal infections, particularly Candida albicans, can cause economic losses in the poultry industry. This study used MLST to analyze C. albicans isolated from geese and ducks in Hungary, revealing the intra-species transmission of three known genotypes and the identification of two novel allele combinations. Phylogenetic analysis showed the relationship between these genotypes, indicating that C. albicans is exposed to lesser selective pressure in animal hosts. The increasing genetic information in the MLST database can help disease prevention strategies.

Summary: This study presents a comprehensive analysis of Vibrio cholerae O1 and non-O1/non-O139 serogroups isolated from environmental water sources in Odisha, India between 2007 and 2019. The strains were analyzed for their genotypes, antibiogram profiles, and pulsotypes. The results showed that the O1 strains carried ctxB1, ctxB3, and ctxB7 genotypes, while the non-O1/non-O139 strains only had ctxB1 genotype. Both O1 and non-O1/non-O139 strains exhibited multiple antibiotic resistances, with the latter showing higher prevalence of resistance-associated genes. The study highlights the changing epidemiology and antibiogram patterns of Vibrio cholerae strains in Odisha.

Summary: This study investigates the dynamics of microbial associations in a 10-year marine time series in the Mediterranean Sea. The results show that marine microbial associations exhibit recurrent seasonal changes and collapse and reassemble when transitioning between colder and warmer waters. Additionally, the study finds that microbial associations are more repeatable in colder months. These findings contribute to a better understanding of the functioning of the ocean microbiome.

Summary: This study collected samples of Puccinia triticina from different provinces in China and tested them using 13 simple sequence repeat (SSR) primers. The results revealed frequent gene exchange within P. triticina populations in China, but also showed distinct population divergence between those in Xinjiang and Yunnan provinces. Additionally, Inner Mongolia was found to be a possible source of P. triticina for other regions, and the linkage disequilibrium test indicated clonal reproduction of urediniospores in P. triticina populations.

Summary: Recent advances in neuroscience have challenged the notion of conscious visual perception as a continuous process, suggesting that oscillatory brain activity may play a role in influencing behavioral performance and visual illusions within the visual system. By investigating the causal relationship between occipital alpha oscillations and Temporal Order Judgements using neural entrainment via rhythmic TMS, the study demonstrates that the phase of entrained oscillations can both facilitate and hinder temporal order perception of visual stimuli. The findings support the idea that visual processing is discrete rather than continuous, and can be modulated by cortical rhythms, providing causal evidence for endogenous periodic modulation of time perception through TMS.

Summary: Blast disease is a notorious fungal disease causing dramatic yield losses on major food crops like rice and wheat. The emergence of blast disease on maize in Iran, as well as epidemics on barnyard grass, raises concerns about potential yield losses and geographic expansion of the disease. Phylogenetic analyses indicate independent host-range expansion events from barnyard grass to maize.

Summary: Genomic regions determining sexual compatibility often display recombination suppression, which can extend beyond the genes determining sexes or mating types, maintaining the multiallelic combinations required for correct compatibility determination. Recent evidence shows expansions of recombination suppression beyond mating-type genes in fungi, which have been little studied and may be more pervasive than commonly thought. The study of recombination suppression in fungi could contribute to our understanding of recombination suppression expansion across a broader range of organisms.

Summary: Felsenstein introduced a model in 1981 to explore the role of genetic constraints in speciation. He described the process of speciation through the accumulation of linkage disequilibrium, showing that recombination inhibits speciation. These insights have laid the foundation for empirical and theoretical studies of speciation.

Summary: Invasions by fungal plant pathogens pose a significant threat to agricultural ecosystems. Through population genomics study of Colletotrichum truncatum, a polyphagous and invasive pathogen of soybean in Brazil, it was found that the pathogen is subdivided into three phylogenetically distinct lineages that exchange genetic variation through hybridization. Introgressed regions, which comprise secreted protein-encoding genes, may be the targets of co-evolutionary selection. Population genomic studies can help identify high-risk geographical areas and pathogens, providing valuable information for future crop protection strategies.

Summary: Hybridization and adaptation to new hosts are important mechanisms of fungal disease emergence. Evaluating the risk of emergence of hybrids with enhanced virulence is crucial for sustainable crop disease management. In this study, the risk of hybridization and its effect on pathogenicity were evaluated in Venturia inaequalis, the fungus responsible for scab disease on Rosaceae hosts. The results showed that there is strict host specificity between isolates from different hosts, but some isolates were still able to cause disease on new hosts. Interestingly, none of the hybrids between different isolates could infect apple, suggesting a potential novel biocontrol strategy.

Summary: Researchers found that recombination suppression between mating-type chromosomes occurred in multiple steps and at least nine independent events linked the mating-type loci together in Microbotryum fungi. Chromosomal rearrangements and recombination suppression are evolutionary mechanisms leading to phenotypic convergence.

Summary: By investigating the genetic and phenotypic relationship between rice landraces and their rice blast pathogen in traditional flooded rice paddies, it was found that specific lineages of rice blast coexisted in the Yuanyang terraces. The study suggests that disease control strategies based on the emergence or maintenance of a generalist lifestyle in pathogens may sustainably reduce the burden of disease in crops.

Summary: In this article, a permutation-based approach is proposed to identify factors significantly correlated with zero-inflated proportion data (ZIPD) which are dependent, continuous and bounded. A performance indicator is introduced to quantify the percentage of correlation explained by the subset of significant factors. The methodology is demonstrated on simulated data and two real data sets in epidemiology, dealing with Influenza transmission probabilities between horses and COVID-19 mortality dynamics in geographic entities.

Summary: Recombination suppression is observed at sex-determining loci in plants and animals, as well as at self-incompatibility or mating-type loci in plants and fungi. In this study, we found that Schizothecium tetrasporum, a fungus from the Sordariales order, also produces mostly self-fertile dikaryotic spores carrying the two opposite mating types due to recombination suppression around the mating-type locus. Our findings indicate a convergent evolution of self-fertile dikaryotic sexual spores across multiple ascomycete fungi and provide insights into the evolutionary causes of recombination suppression.

Summary: This study identified a new population of Penicillium roqueforti specifically found in French Termignon cheeses, which provides a novel source of genetic diversity for cheese making. Additionally, two non-cheese populations that adapt to different ecological niches have not been investigated yet. The results suggest that domestication and adaptation to anthropized environments have occurred in cheese fungi.
