Comparative genomics reveals extensive genomic conservation and limited microdiversification among Xenorhabdus bovienii isolates recovered from a single Steinernema feltiae isolation event.
Xenorhabdus bovienii is a symbiotic bacterium associated with entomopathogenic nematodes of the genus Steinernema. Comparative genomic analyses of closely related isolates provide an opportunity to investigate fine-scale diversification, genome plasticity, and the evolutionary processes shaping symbiotic bacterial populations. Here, we analyzed four X. bovienii isolates (XenUTI4.1-XenUTI4.4) recovered from a single Steinernema feltiae isolation event using comparative genomics approaches...
Alien: Isolation 2 keeps the classic horror game's uncompromising approach to raising tension
Alien: Isolation 2 keeps the classic horror game's uncompromising approach to raising tension We played the opening prologue of the horror sequel, and it's still got ways to bring the scares. One of the best horror games of the 2010s was Creative Assembly's Alien: Isolation, but it certainly took some time for audiences to see it in its proper light. Though it initially received mixed reception for its tense encounters and stark difficulty, it's now seen large reappraisal from horror fans...
Clinical isolates of Mycobacterium avium complex reveal an M. intracellulare-associated IL-17/neutrophilic pulmonary immune program in a murine disease model
Mycobacterium avium complex (MAC) is the leading cause of nontuberculous mycobacterial pulmonary disease (NTM-PD) and mainly comprises M. avium (MAV) and M. intracellulare (MI). Host-pathogen interactions may contribute to the heterogeneous clinical course of MAC pulmonary disease (MAC-PD); however, species- or isolate-associated differences in virulence and host immune responses induced by MAC strains remain poorly understood. Here, we established a panel of MAC clinical isolates exhibiting...
Brazil isolates two suspected Ebola cases as Congo outbreak exceeds 1,000 infections
Brazil isolates two suspected Ebola cases as Congo outbreak exceeds 1,000 infections Brazilian health authorities isolated two patients who recently arrived from African countries after they showed symptoms consistent with Ebola, officials said on Friday, although one later tested negative. The move comes as the Democratic Republic of the Congo battles an outbreak that has surpassed 1,000 suspected cases and nearly 250 deaths since May. Two patients who recently arrived in Brazil from...

Alien Isolation 2's first trailer takes the horror to a colony planet
Alien Isolation 2's first trailer takes the horror to a colony planet The abbreviated name, "AI 2," is the scariest thing about it so far. Time works differently in space and on other planets, so the decade-plus that Alien Isolation fans have been waiting for the sequel might have felt like a blink of an eye on a different world. On terra firma, though, it's been a 12-year wait.
Two patients with Ebola-like symptoms in isolation in Brazil
Two patients with Ebola-like symptoms in isolation in Brazil SAO PAOLO: Two patients who recently arrived in Brazil from African countries have been put in isolation after showing symptoms linked to Ebola, officials said, raising concerns about the deadly virus spreading beyond the African continent. A 37-year-old man who recently traveled to the Democratic Republic of Congo (DRC), where the outbreak has been concentrated, "exhibited symptoms such as fever, meeting the definition of a...
Extracellular vesicles from Manila clam (Ruditapes philippinarum): tailored isolation from hemolymph and insights into water-derived vesicles
Extracellular vesicles (EVs) are evolutionarily conserved mediators of intercellular communication released by cells into biological fluids and the extracellular environment. Despite their growing relevance in biomedical and veterinary research, knowledge on EVs in marine bivalves remains limited. The aim of this study was to optimize tailored protocols for EV isolation from the hemolymph of the Manila clam (Ruditapes philippinarum) based on density gradient ultracentrifugation (dgUC) or...
Genomic architecture and adaptive plasticity of Enterococcus lactis strains isolated from extreme Semi-arid environments
The presence of Enterococcus lactis in "resource islands" the remarkable ecological plasticity of a species often associated with host-related environments. Characterizing the genomic mechanisms that facilitate its persistence in extreme edaphic niches is crucial for exploring its biotechnological potential in arid agriculture. This study characterized the genomic architecture, abiotic stress tolerance, and plant growth-promoting (PGP) capabilities of six E. lactis strains isolated from the...
Impairment of bacteriophage activity in blood: a case study revealing constraints in phage isolation and translation
Background Phage therapy is increasingly considered a promising alternative for treating multidrug-resistant (MDR) infections. However, its clinical application remains limited by challenges in isolating effective phages against resistant clinical strains and by the limited ability of in vitro assays to predict performance in real biological environments. While biological matrices are known to influence phage activity, these effects are not well characterised.
