Is fresh-waterHydra vulgaris attenuata a spirochaetales' reservoir host?

Experientia, 1969
Osservazioni al M.E. di esemplari diHydra vulgaris attenuata hanno messo in evidenza la presenza di spirochetali nello strato mesogleale. Si fa l'ipotesi che le spirochete siano inquiline di questi polipi d'acqua dolce. Le idre potrebbero forse anche rappresentare un serbatoio di spirochete patogene per altri animali.

Phosphofructokinase activities within the order Spirochaetales and the characterisation of the pyrophosphate-dependent phosphofructokinase from Spirochaeta thermophila

Archives of Microbiology, 1999
The subtype of phosphofructokinase activity, either ATP-, ADP- or pyrophosphate-dependent, present in members of three genera from the Spirochaetales was investigated. The individual species/strains examined included Spirochaeta alkalica, S. asiatica, S. halophila, S. isovalerica, S. litoralis, S. zuelzerae, S. thermophila, two thermophilic spirochetes,

Ticks (Acari: Ixodidae) and Spirochetes (Spirochaetaceae: Spirochaetales) Recovered from Birds on a Georgia Barrier Island

Journal of Medical Entomology, 2001
From September 1997 through July 1999, 300 individuals and 46 species of birds were mist-netted and screened for ticks and spirochetes on St. Catherine's Island, Liberty County, GA. Seventy-six (25%) of the birds were parasitized by a meal intensity of 4.6 ticks.

Adhesion to and Invasion of Cultured Tick (Acarina: Ixodidae) Cells by Borrelia burgdorferi (Spirochaetales: Spirochaetaceae) and Maintenance of Infectivity

Journal of Medical Entomology, 1993
Lyme disease spirochetes, Borrelia burgdorferi, interact with cultured tick cells in ways similar to those reported to occur in the vector Ixodes dammini Spielman, Clifford, Piesman & Corwin. Spirochete adhesion and penetration were examined using a cell line from embryos of Rhipicephalus appendiculatus Neumann that morphologically resembles tick gut ...

16S rDNA Analysis of Spirochaeta thermophila: Its Phylogenetic Position and Implications for the Systematics of the Order Spirochaetales

Systematic and Applied Microbiology, 1992
The 16S rRNA gene of Spirochaeta thermophila DSM 6578 was amplifed by the polymerase chain reaction and analysis of a 1333 nucleotide long stretch performed. The sequence was aligned to the homologous region of 13 representatives from six spirochete genera, and the phylogenetic position of S. thermophila determined.

Prevalence ofBorrelia burgdorferi(Spirochaetales: Spirochaetaceae) inIxodes scapularis(Acari: Ixodidae) Adults in New Jersey, 2000–2001

Journal of Medical Entomology, 2003
Using polymerase chain reaction, we analyzed 529 Ixodes scapularis Say adults collected from 16 of New Jersey's 21 counties for the presence of Borrelia burgdorferi, the etiological agent of Lyme disease. Overall, 261 (49.3%) were positive. B. burgdorferi was detected in ticks obtained from each county and from 53 of the 58 (93.1%) municipalities ...

Attempted Transmission of Borrelia burgdorferi (Spirochaetales: Spirochaetaceae) (Jdi Strain) by Ixodes scapularis (Acari: Ixodidae), Dermacentor variabilis, and Amblyomma americanum

Journal of Medical Entomology, 1992
Laboratory-reared Ixodes scapularis Say, Amblyomma americanum (L.), and Dermacentor variabilis (Say) were fed on New Zealand white rabbits experimentally infected with Borrelia burgdorferi (JDI strain). At repletion, spirochetes could be detected by dark-field microscopy only in I. scapularis. Acquisition rates were 18 and 21%.

Presence ofBorrelia turdiandBorrelia valaisiana(Spirochaetales: Spirochaetaceae) in Ticks Removed From Birds in the North of Spain, 2009–2011

Journal of Medical Entomology, 2016
The genus Borrelia includes species responsible for severe human diseases such as Lyme disease. Birds are involved in their epidemiology as dispersers of infected ticks (Ixodida: Ixodidae) and as reservoirs or amplifiers of the bacterium. Herein, the presence of Borrelia burgdorferi sensu lato (s.l.) Johnson, Schmid, Hyde, Steigerwalt & Brenner in 336 ...
