Estudio de comunidades bacterianas naturales: diferenciación de las actinobacterias mediante electroforesis en doble gel en gradiente de desnaturalización (DDGGE)

, 2005
El primer objetivo, en esta Tesis, es la optimización de las condiciones a emplear para el estudio de comunidades bacterianas naturales. Esto se conseguirá mejorando los gradientes empleados en los geles en condiciones desnaturalizantes.

Investigation of 222‐nm ultraviolet C irradiation bactericidal effect on the surgical field in a rabbit model

Photochemistry and Photobiology, EarlyView.
In a rabbit surgical field model seeded with polymicrobial flora, a single dose of 222‐nm UV‐C (500 mJ/cm2) markedly reduced bacterial colonies, achieving a bactericidal effect comparable to 254‐nm UV‐C (200 mJ/cm2), while no UV‐C irradiation showed heavy growth. Wound healing did not differ among groups. Microbiota profiling detected SSI‐relevant taxa

Skin Commensal Microbiota Does Not Influence the Clinical Course of Dermatophyte Infection in Persian Cats

Veterinary Dermatology, EarlyView.
Dermatophytes can be isolated from both symptomatic and asymptomatic cats, yet the role of skin commensals in modulating disease expression remains unclear. This study investigates whether microbial skin communities influence the clinical presentation (symptomatic or asymptomatic) of dermatophyte infection in Persian cats.

Clinical Efficacy of Probiotic‐Based Ear Drops Containing Lactobacilli in Canine Erythroceruminous Otitis Externa: An Open Label, Multicentre Study

Veterinary Dermatology, EarlyView.
Background: Otitis externa (OE) represents a common clinical problem in dogs. Allergic dogs exhibit reduced diversity of the otic microbiota, and inflammation‐induced changes in the ear canal microenvironment result in a further decline in microbial biodiversity.

Fast and Sensitive Measurement of Off‐Flavors in Recirculating Aquaculture Systems

Rapid Communications in Mass Spectrometry, Volume 40, Issue 15, 15 August 2026.
ABSTRACT Rationale Geosmin and 2‐methylisoborneol (2‐MIB) are odor‐active compounds responsible for earthy off‐flavors in fish, creating significant quality concerns in recirculating aquaculture systems (RAS). Their extremely low odor thresholds make rapid and highly sensitive detection essential for maintaining product quality and consumer acceptance ...

Vancomycin Protects Against Lung Injury and Promotes Butyrate Metabolism

The FASEB Journal, Volume 40, Issue 13, 15 July 2026.
Transplanting the fecal microbiota of patients with lung injury into mice causes an increase in LPS in the mice's blood, thereby leading to chronic lung injury in the mice. Meanwhile, oral administration of vancomycin can enhance colonic butyrate metabolism and improve lung injury in mice.

Intratumoral Microbiota in Tumor: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 7, July 2026.
Intratumoral bacteria are emerging as active regulators of cancer evolution rather than bystanders. This review outlines how tumor‐resident microbes drive tumor initiation and growth by inducing genomic instability, epigenetic reprogramming, oncogenic signaling, and chronic inflammation, while promoting metastatic spread via invasion, angiogenesis ...
