  • Defined Microbiome Profiles Can Improve Mouse Model Predictability


    It is well documented that the microbiome can impact both the development of disease and the efficacy of therapeutics. The microbiome also is consistently cited as a significant contributor to preclinical study variability and reproducibility, in part due to its effects on a mouse model’s predictability. With a strong incentive to better understand the role […]

  • Landmark paper calls for need to develop the world’s microbiome biobanking infrastructure


    A team of scientists led by CABI’s Dr. Matthew Ryan has outlined a series of challenges and opportunities presented in a necessary review of how microbiomes—biological communities including bacteria, archaea, fungi, algae, protists and viruses—can be ‘banked’ and preserved for generations to come. The researchers, who call for a prioritized list of what should be […]

This is critical to prevent contamination within a gnotobiotic facility. Download this webinar to learn about appropriate validation of supply sterilization and recommended monitoring techniques for germ-free and gnotobiotic isolators. By watching you can learn: Autoclave, […]

    Dr. Cristina Weiner recently presented a webinar featuring a novel approach to germ-free derivations. She discussed the importance of understanding baseline performance and making incremental process improvements as well as how Taconic Biosciences developed and implemented a new facility design which supports improved germ-free derivation success. Q: You stated during the presentation that, on balance, […]

  • Time For Better Microbiome Research


    The microbiome needs no introduction – it has been several years since you could pick up a biomedical research journal and not run into an article on possible connections of human gut bacteria and disease. There were thousands of such papers last year alone. But it’s a very hard field to work in. You can […]

  • Bifidobacterium longum counters the effects of obesity: Partial successful translation from rodent to human


    Abstract Background The human gut microbiota has emerged as a key factor in the development of obesity. Certain probiotic strains have shown anti-obesity effects. The objective of this study was to investigate whether Bifidobacterium longum APC1472 has anti-obesity effects in high-fat diet (HFD)-induced obese mice and whether B. longum APC1472 supplementation reduces body-mass index (BMI) […]

  • Reducing versus Embracing Variation as Strategies for Reproducibility: The Microbiome of Laboratory Mice


    Abstract Irreproducibility is a well-recognized problem in biomedical animal experimentation. Phenotypic variation in animal models is one of the many challenging causes of irreproducibility. How to deal with phenotypic variation in experimental designs is a topic of debate. Both reducing and embracing variation are highlighted as strategies for reproducibility. In this theoretical review, we use […]

  • Acute and long-term effects of antibiotics commonly used in laboratory animal medicine on the fecal microbiota


    Abstract Biomedical research relies on the use of animal models, and the animals used in those models receive medical care, including antibiotics for brief periods of time to treat conditions such as dermatitis, fight wounds, and suspected bacterial pathogens of unknown etiology. As many mouse model phenotypes are sensitive to changes in the gut microbiota, […]

  • Gut microbiome alterations induced by tributyltin exposure are associated with increased body weight, impaired glucose and insulin homeostasis and endocrine disruption in mice


    Abstract Tributyltin (TBT), an organotin compound once widely used in agriculture and industry, has been reported to induce obesity and endocrine disruption. Gut microbiota has a strong connection with the host’s physiology. Nevertheless, the influences of TBT exposure on gut microbiota and whether TBT-influenced gut microbiota is related to TBT-induced toxicity remain unclear. To fill […]

  • Faecal microbiota transplant from aged donor mice affects spatial learning and memory via modulating hippocampal synaptic plasticity- and neurotransmission-related proteins in young recipients


    Abstract Background The gut-brain axis and the intestinal microbiota are emerging as key players in health and disease. Shifts in intestinal microbiota composition affect a variety of systems; however, evidence of their direct impact on cognitive functions is still lacking. We tested whether faecal microbiota transplant (FMT) from aged donor mice into young adult recipients […]

  • The maternal microbiome modulates fetal neurodevelopment in mice


    Abstract ‘Dysbiosis’ of the maternal gut microbiome, in response to challenges such as infection1, altered diet2 and stress3 during pregnancy, has been increasingly associated with abnormalities in brain function and behaviour of the offspring4. However, it is unclear whether the maternal gut microbiome influences neurodevelopment during critical prenatal periods and in the absence of environmental […]

  • The gut microbiota may be a novel pathogenic mechanism in loosening of orthopedic implants in rats


    Abstract Particles released from implants cause inflammatory bone loss, which is a key factor in aseptic loosening, the most common reason for joint replacement failure. With the anticipated increased incidence of total joint replacement in the next decade, implant failure will continue to burden patients. The gut microbiome is increasingly recognized as an important factor […]

  • Obesity Worsens Gulf War Illness Symptom Persistence Pathology by Linking Altered Gut Microbiome Species to Long-Term Gastrointestinal, Hepatic, and Neuronal Inflammation in a Mouse Model


    Abstract Persistence of Gulf War illness (GWI) pathology among deployed veterans is a clinical challenge even after almost three decades. Recent studies show a higher prevalence of obesity and metabolic disturbances among Gulf War veterans primarily due to the existence of post-traumatic stress disorder (PTSD), chronic fatigue, sedentary lifestyle, and consumption of a high-carbohydrate/high-fat diet. […]

  • In vivo antiviral host transcriptional response to SARS-CoV-2 by viral load, sex, and age


    Abstract Despite limited genomic diversity, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has shown a wide range of clinical manifestations in different patient populations. The mechanisms behind these host differences are still unclear. Here, we examined host response gene expression across infection status, viral load, age, and sex among shotgun RNA sequencing profiles of nasopharyngeal […]
