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 ...

Arf6 is recruited by R. typhi RalF and is required for infection.

, 2015
(A) Ectopically expressed RalFRtFL co-localizes with Arf6 but not Arf5. HeLa cells co-expressing EYFP, EYFP-RalFRtFL or EYFP-RalFRbFL and mRFP-Arf6 (left) or -Arf5 (right) were fixed with 4% para-formaldehyde. Nuclei were stained with DAPI (blue). (Scale

Improved Detection and Sequencing of Rickettsia spp. DNA in South African Wildlife

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Nested gltA PCR detected Rickettsia spp. DNA in 44% of South African wildlife samples previously negative by RLB, revealing spotted fever, typhus and transitional group lineages, novel host records, co‐infection and multi‐organ dissemination in impala, highlighting complex wildlife involvement and zoonotic risk within a One Health framework.

Murine Typhus and Leptospirosis as Causes of Acute Undifferentiated Fever, Indonesia [PDF]

, 2009
To investigate rickettsioses and leptospirosis among urban residents of Semarang, Indonesia, we tested the blood of 137 patients with fever. Evidence of Rickettsia typhi, the agent of murine typhus, was found in 9 patients.

The pipB Gene as Target for Development of Detection Method of Pathogenic Bacteria Salmonella typhi Using Real-time Polymerase Chain Reaction

Hayati Journal of Biosciences
Salmonella typhi is a bacteria that leads to typhoid fever and one of the causes of death due to bacteria infections. In Indonesia, typhoid fever occurs around 1,100 cases per 100,000 population per year, with a mortality rate of 3.1-10.4%.

MΦ hardly respond to R. typhi and are uncapable to kill the bacteria.

, 2016
To analyze a correlation of bacterial uptake and activation status of CD11b+GR1low MΦ /monocytes and CD11b+GR1hi neutrophils in vivo the respective cell population in the spleen and liver of the mice described in Fig 5 was first gated on iNOS+ cells and ...

Stimuli‐Responsive Crosslinked Chitosan/PVP/PEG Hydrogel Networks for Targeted Drug Delivery and Antimicrobial Performance

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT In this study, a unique pH‐sensitive PEG/C/PVA hydrogel based on chitosan (C), polyvinyl propylene (PVP) and polyethylenglycol (PEG) crosslinked with tetraethyl orthosilicate (TEOS) was fabricated. This PEG/C/PVA hydrogel was designed to deliver different drugs with distinct release profiles, including diclofenac sodium and ciprofloxacin, and ...
