Host-associated microbial communities play an important role in the fitness of insect hosts. However, the factors shaping microbial communities in wild populations, including environmental factors and interactions among microbial species, remain largely unknown. The tea green leafhopper has a wide geographical distribution and is highly adaptable, providing a suitable model for studying the effect of ecological drivers on microbiomes. This is the first large-scale culture-independent study investigating the microbial communities of sampled from different locations. Altitude as a key environmental factor may have shaped microbial communities of by affecting the relative abundance of endosymbionts, especially . The results of this study, therefore, offer not only an in-depth view of the microbial diversity of this species but also an insight into the influence of environmental factors.

Statement Of Problem: Harmony between prostheses and periodontal tissues is essential. The presence of a fixed prosthesis has been reported to increase the risk of periodontal lesion onset in abutment teeth and to affect longevity. However, studies comparing the supragingival plaque biofilm on fixed prostheses and natural teeth are lacking.

Prokaryotes (Bacteria and Archaea) encode a highly diversified arsenal of defence systems that protect them against mobile genetic elements, such as phages and plasmids. In turn, mobile genetic elements encode anti-defence systems that allow them to escape the activity of these defence systems. This has resulted in an evolutionary arms race in which defence systems and anti-defence systems evolve and adapt continuously, driving intriguing innovation and enormous diversification on both sides.

Recent molecular and metagenomic studies have revealed that the obligate anaerobic protist Blastocystis is found more prevalently and with higher subtype diversities in herbivore species than in carnivore species. However, information on wild carnivore species is scarce. Here, we investigated the presence of Blastocystis by molecular methods in fecal DNA samples of free-ranging and captive Iberian lynxes from Spain (n = 243) and Portugal (n = 30).

The emergence of bacterial resistance and the increasing restrictions on the use of agrochemicals are boosting the search for novel, sustainable antibiotics. Antimicrobial peptides (AMPs) arise as a new generation of antibiotics due to their effectiveness at low doses and biocompatibility. We compared the antimicrobial activity of four promising AMPs (CA-M, BP100, RW-BP100, and 3.

In this study, male Sprague-Dawley (SD) rats were exposed to bisphenol S (BPS) at environmentally relevant concentrations to investigate its reproductive toxicity and evaluate its effects on the gut-blood-testicular axis. After 28 days of exposure to BPS (0.05 and 20 mg/kg), the results showed a reduction in weight gain and the induction of reproductive toxicity in male rats, including decreased sperm parameters, lower sperm viability, and increased abnormal sperm density and mortality.
