Epidemiological Characteristics of Field Tick-Borne Pathogens in Gwang-ju Metropolitan Area, South Korea, from 2014 to 2018 [PDF]

Osong Public Health and Research Perspectives, 2020
Objectives The importance of tick-borne diseases is increasing because of climate change, with a lack of long-term studies on tick-borne pathogens in South Korea.

No Mate, No Problem: Molecular Mechanisms Involved in Parthenogenesis in the Cosmopolitan Earthworm Aporrectodea trapezoides (Annelida, Clitellata)

Molecular Ecology, EarlyView.
ABSTRACT Approximately, 40% of earthworm species can reproduce by parthenogenesis. This is the case for the cosmopolitan species, Aporrectodea trapezoides, although sexual forms have been described sporadically. We analyse the genotypes and microbiomes of 30 individuals from four localities where both forms appear in order to understand the ...

Diversity of Rickettsia species in collected ticks from Southeast Iran

BMC Veterinary Research
Rickettsia occurs worldwide and rickettsiosis is recognized as an emerging infection in several parts of the world. Ticks are reservoir hosts for pathogenic Rickettsia species in humans and domestic animals.

Phylogenies of atpD and recA support the small subunit rRNA-based classification of rhizobia [PDF]

, 2001
The current classification of the rhizobia (root-nodule symbionts) assigns them to six genera. It is strongly influenced by the small subunit (16S, SSU) rRNA molecular phylogeny, but such single-gene phylogenies may not reflect the evolution of the ...

Luminal Phospholipase D Attacks Bacterial Membranes in Dictyostelium discoideum Phagosomes

Molecular Microbiology, EarlyView.
This study shows that PldX, a luminal Phospholipase D, is necessary for the efficient destruction of ingested Klebsiella pneumoniae bacteria in Dictyostelium discoideum phagosomes. PldX and the AlyL lysozyme together attack the bacterial membrane and permeabilize it. To date, the molecular substrate of PldX remains to be determined. ABSTRACT Phagocytic

Advances in Rickettsia Pathogenicity

Annals of the New York Academy of Sciences, 2009
One century after the first description of rickettsiae as human pathogens, the rickettsiosis remained poorly understood diseases. These microorganisms are indeed characterized by a strictly intracellular location which has, for long, prohibited their detailed study.

DIRECT FLUOROCHROMING OF RICKETTSIAE [PDF]

Journal of Histochemistry & Cytochemistry, 1964
Several fluorochromes were used to stains directly R. mooseri in smears and tissues. The effects of fixatives, hydrogen ion concentration, time in stain and concentration of stain were studied also. Interference by background fluoresence was minimized by a preliminary staining of fixed preparations with an alcian blue, periodic acid-Schiff sequence ...

tRNA signatures reveal polyphyletic origins of streamlined SAR11 genomes among the alphaproteobacteria [PDF]

, 2013
Phylogenomic analyses are subject to bias from compositional convergence and noise from horizontal gene transfer (HGT). Compositional convergence is a likely cause of controversy regarding phylogeny of the SAR11 group of Alphaproteobacteria that have ...

Spatial and temporal analyses of Dermacentor variabilis (Say) (Acari: Ixodidae) in central and eastern Canada

Medical and Veterinary Entomology, EarlyView.
One thousand one hundred ninety‐eight adult Dermacentor variabilis (Say), a species of veterinary and human medical importance, were collected from companion animals in central and eastern Canada. Peaks in adult D. variabilis submissions occurred in May and June across the provinces. Most submissions of adult D.
