Tick Ecdysteroid Hormone, Global Microbiota/Rickettsia Signaling in the Ovary versus Carcass during Vitellogenesis in Part-Fed (Virgin) American Dog Ticks, Dermacentor variabilis

MICROORGANISMS, 9(6).

By: L. Ponnusamy n, H. Sutton n, R. Mitchell n, D. Sonenshine*, C. Apperson n & R. Roe n

author keywords: Dermacentor variabilis; ecdysteroid; Rickettsia sp; Francisella sp; qPCR; microbiota
TL;DR: Injections of physiological levels of the tick hormone, 20-hydroxyecdysone (20E), into part-fed (virgin) adult females of the American dog tick, Dermacentor variabilis, attached to the host caused a reduction in density of Rickettsia montanensis in the carcass and an increase in the ovaries compared to buffer-injected controls.

2016 journal article

Development and Validation of an Improved PCR Method Using the 23S-5S Intergenic Spacer for Detection of Rickettsiae in Dermacentor variabilis Ticks and Tissue Samples from Humans and Laboratory Animals

JOURNAL OF CLINICAL MICROBIOLOGY, 54(4), 972–979.

By: M. Kakumanu n, L. Ponnusamy n, H. Sutton n, S. Meshnick*, W. Nicholson* & C. Apperson n

MeSH headings : Animals; Animals, Laboratory; DNA Primers / genetics; DNA, Intergenic / chemistry; DNA, Intergenic / genetics; Dermacentor / microbiology; Humans; Nucleic Acid Hybridization; Oligonucleotide Probes / genetics; Polymerase Chain Reaction / methods; RNA, Ribosomal, 23S / genetics; RNA, Ribosomal, 5S; Rickettsiaceae Infections / diagnosis; Rickettsiaceae Infections / microbiology; Rickettsieae / classification; Rickettsieae / genetics; Rickettsieae / isolation & purification; Sensitivity and Specificity
TL;DR: The novel nested PCR assay was sensitive enough to detect one copy of a cloned 23S-5S IGS fragment from “Candidatus Rickettsia amblyommii,” and validated using clinical samples from humans and laboratory animals that were known to be infected with pathogenic species ofRickettsia.

Prevalence of Rickettsiales in ticks removed from the skin of outdoor workers in North Carolina

PARASITES & VECTORS, 7.

By: S. Lee n, M. Kakumanu n, L. Ponnusamy n, M. Vaughn*, S. Funkhouser*, H. Thornton n, S. Meshnick*, C. Apperson n

author keywords: Ticks; Rickettsiales pathogens; Rickettsia; Ehrlichia; Reverse line blot hybridization
MeSH headings : Animals; Arachnid Vectors / microbiology; Base Sequence; DNA, Bacterial / chemistry; DNA, Bacterial / genetics; DNA, Ribosomal / chemistry; DNA, Ribosomal / genetics; Double-Blind Method; Female; Humans; Ixodidae / microbiology; Male; Molecular Sequence Data; North Carolina / epidemiology; Polymerase Chain Reaction; Prevalence; Rickettsia / genetics; Rickettsia / isolation & purification; Rickettsia Infections / epidemiology; Rickettsia Infections / microbiology; Sequence Analysis, DNA; Tick Infestations / epidemiology
TL;DR: It is concluded that in North Carolina, the most common rickettsial exposure is to R. amblyommii carried by A. americanum, and Rickettsiales bacteria, including novel species of Rickettsia, were less frequently detected in A.Americanum. (via Semantic Scholar)
