“…Our results on the microbiome composition of the untreated samples are congruent with the findings of the five previous studies on P. surinamensis microbiome, which employed amplicon sequencing ( 18 – 21 , 64 ). Our study is, to the best of our knowledge, the first one exploring the gut microbiome of P. surinamensis with shotgun metagenomic sequencing.…”

Antimicrobial resistance (AMR) is a major global health concern, further complicated by its spread via the microbiome bacterial members. While mathematical models discuss AMR transmission through the symbiotic microbiome, experimental studies are scarce. Herein, we used a gregarious cockroach, Pycnoscelus surinamensis, as an in vivo animal model for AMR transmission investigations. We explored whether the effect of antimicrobial treatment is detectable with metagenomic sequencing, and whether AMR genes can be spread and established in unchallenged (not treated with antibiotics) individuals following contact with treated donors, and under various frequencies of interaction. Gut and soil substrate microbiomes were investigated by metagenomic sequencing for bacterial community composition and resistome profiling. We found that tetracycline treatment altered the treated gut microbiome by decreasing bacterial diversity and increasing the abundance of tetracycline resistance genes. Untreated cockroaches that interacted with treated donors also had elevated tetracycline resistance. The levels of resistance differed depending on the magnitude and frequency of donor transfer. Additionally, treated donors showed signs of microbiome recovery due to their interaction with the untreated ones. Similar patterns were also recorded in the soil substrate microbiomes. Our results shed light on how interacting microbiomes facilitate AMR gene transmission to previously unchallenged hosts, a dynamic influenced by the interaction frequencies, using an in vivo model to validate theoretical AMR transmission models. IMPORTANCE Antimicrobial resistance is a rising threat to human and animal health. The spread of resistance through the transmission of the symbiotic gut microbiome is of concern and has been explored in theoretical modeling studies. In this study, we employ gregarious insect populations to examine the emergence and transmission of antimicrobial resistance in vivo and validate modeling hypotheses. We find that antimicrobial treatment increases the levels of resistance in treated populations. Most importantly, we show that resistance increased in untreated populations after interacting with the treated ones. The level of resistance transmission was affected by the magnitude and frequency of population mixing. Our results highlight the importance of microbial transmission in the spread of antimicrobial resistance.

“…Moreover, the cockroach gut microbiomes, akin to other insects, are rich in bacterial taxa and play pivotal roles in digestion, nutrient assimilation, and overall health ( 17 ). Yet, only a handful of studies have examined the gut microbiome of P. surinamensis , while no study has ever explored its resistome ( 18 – 21 ).…”

“…Arthrobacter and Actinomyces and Streptomyces produced arthrofactin, a lipopeptide biosurfactant type (71). The surface and interfacial behavior of arthrofactin is noteworthy as this cyclic lipopeptide (at a concentration of 100 µM) can reduce the surface tension of water from 72 to 24 mNm-1 (72).…”

Biosurfactants can be used for bioremediation as amphiphilic compounds that have shown good tolerance to changes in temperature, salt concentration, pH, and other environmental factors. They have received increased attention in bioremediation because they are biodegradable and do not generate any secondary contaminants. Biosurfactants are used to remove organic molecules for example hydrocarbon contaminants through various mechanisms such as surface tension reduction, emulsification, and micelle formation. They can also play a role in removing heavy metals by increasing contact with the surface of heavy metal deposits and forming complexes and micelle formation. In this review, we focus on the role of biosurfactants in improving the efficacy of bioremediation.

“…Studies have shown decomposer invertebrates can increase litter mass loss and nutrient release either in partnership with symbiotic microbes or using endogenous cellulases (Ashton et al., 2019; Eggleton & Tayasu, 2001; Griffiths et al., 2019). Earthworms, beetles, isopods and millipedes can produce extracellular cellulases in partnership with gut symbionts (de Jonge et al., 2023; Ni'matuzahroh et al., 2022; Pauchet et al., 2010). In addition, and apart from gut symbionts, some termite groups are also capable of producing endogenous cellulases to digest dead organic matter through invertebrate‐enzymatic decomposition without the support of microbes (Griffiths, Ashton, et al., 2021; Pauchet et al., 2010).…”

Forest litter decomposition is an essential component of global carbon and nutrient turnover. Invertebrates play important roles in litter decomposition, but the regional pattern of their effects is poorly understood. We examined 476 case studies across 93 sites and performed a meta‐analysis to estimate regional effects of invertebrates on forest litter decomposition. We then assessed how invertebrate diversity, climate and soil pH drive regional variations in invertebrate‐mediated decomposition. We found that (1) invertebrate contributions to litter decomposition are 1.4 times higher in tropical and subtropical forests than in forests elsewhere, with an overall contribution of 31% to global forest litter decomposition; and (2) termite diversity, together with warm, humid and acidic environments in the tropics and subtropics are positively associated with forest litter decomposition by invertebrates. Our results demonstrate the significant difference in invertebrate effects on mediating forest litter decomposition among regions. We demonstrate, also, the significance of termites in driving litter mass loss in the tropics and subtropics. These results are particularly pertinent in the tropics and subtropics where climate change and human disturbance threaten invertebrate biodiversity and the ecosystem services it provides.
