Intracellular localization of Treponema denticola chymotrypsin-like proteinase in chronic periodontitis

Journal of Oral Microbiology, 2014
Treponema denticola is an important periodontal pathogen capable of tissue invasion. Its chymotrypsin-like proteinase (CTLP) can degrade a number of basement membrane components in vitro, thus suggesting a contribution to tissue invasion by the ...

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Syphilis is a re‐emerging global public health concern; recently, its incidence has significantly increased in all demographic groups. However, acute syphilitic posterior placoid chorioretinitis (ASPPC) and syphilitic optic neuropathy in a patient with human immunodeficiency virus (HIV) co‐infection are extremely uncommon.

Unraveling Oral Dysbiosis: Microbial Complexity in Common Oral Diseases

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
The oral microbiome undergoes dynamic establishment from birth, maturing into a resilient ecosystem. Perturbation of this homeostasis—driven by dietary, immunological, and anatomical factors—triggers dysbiosis, which underpins the pathogenesis of major oral diseases, including dental caries, periodontal disease, salivary gland disorders, oral mucosal ...

Borrelia recurrentis employs a novel multifunctional surface protein with anti-complement, anti-opsonic and invasive potential to escape innate immunity

, 2009
Borrelia recurrentis, the etiologic agent of louse-borne relapsing fever in humans, has evolved strategies, including antigenic variation, to evade immune defence, thereby causing severe diseases with high mortality rates.

Full‐Length 16S and 18S rRNA Long‐Read Sequencing Reveals Gut Microbiome Diversity in the European Brown Hare (Lepus europaeus)

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Full‐length 16S and 18S rRNA Oxford Nanopore sequencing of large intestine contents from 30 healthy European brown hares revealed broad gut microbiome diversity. An 80% identity threshold detected substantially greater taxonomic richness than 95%, emphasizing the value of long‐read sequencing in wildlife microbiome research. ABSTRACT The European brown

SPIROCHETAL PULMONARY GANGRENE [PDF]

Archives of Internal Medicine, 1921
Ever since Obermeier, in 1873, reported the presence of microorganisms of the genus spirocheta, or spirilla, in the blood of patients with relapsing fever, many diseases have been found to be caused by varieties of this species. The most important disease due to spirochetal infection is, of course, syphilis, to which etiologic relationship of the ...

THE PRESENCE OF SPIROCHETES IN THE KIDNEY [PDF]

JAMA: The Journal of the American Medical Association, 1918
In May, 1917, at Tokyo, Futaki demonstrated spirochetes in the urine and the renal casts of typhusinfected kidneys, and reported them as the specific causative agent of typhus fever. Two months later, Futaki's report was discussed by Miyashima, Kusama and Koga.
