Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

Ecography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

The Tad pilus apparatus of Candidatus Liberibacter asiaticus and its regulation by VisNR.

Molecular Plant-Microbe Interactions, 2019
Huanglongbing (HLB) is one of the most destructive diseases affecting citrus plants. Candidatus Liberibacter asiaticus (CLas), an uncultivated α-proteobacteria, is the most widely spread causal agent of HLB and transmitted by the Asian citrus psyllid ...

Crossed cerebellar diaschisis in status epilepticus: A systematic review of the literature

Epileptic Disorders, EarlyView.
Abstract Objective Crossed cerebellar diaschisis is a neuroimaging phenomenon observed in various neurological conditions, including status epilepticus. This systematic review aims to summarize the clinical and radiological characteristics of patients developing crossed cerebellar diaschisis following status epilepticus and to discuss potential ...

Identification and Characterization of Type IV Pili as the Cellular Receptor of Broad Host Range Stenotrophomonas maltophilia Bacteriophages DLP1 and DLP2

Viruses, 2018
Bacteriophages DLP1 and DLP2 are capable of infecting both Stenotrophomonas maltophilia and Pseudomonas aeruginosa strains, two highly antibiotic resistant bacterial pathogens, which is unusual for phages that typically exhibit extremely limited host ...

Role and regulation of the Flp/Tad pilus in the virulence of Pectobacterium atrosepticum SCRI1043 and Pectobacterium wasabiae SCC3193. [PDF]

PLoS ONE, 2013
In this study, we characterized a putative Flp/Tad pilus-encoding gene cluster, and we examined its regulation at the transcriptional level and its role in the virulence of potato pathogenic enterobacteria of the genus Pectobacterium.

The Remarkable Biomechanical Properties of the Type 1 Chaperone-Usher Pilus: A Structural and Molecular Perspective

Microbiology spectrum, 2019
Chaperone-usher (CU) pili are long, supramolecular protein fibers tethered to the surface of numerous bacterial pathogens. These virulence factors function primarily in bacterial adhesion to host tissues, but they also mediate biofilm formation.

A Novel Fetal Intracranial Measurement Contributing to the Differential Diagnosis of Fetal Microcephaly

Journal of Ultrasound in Medicine, EarlyView.
Objectives To evaluate the value of the thickness of the frontal lobe (TFL) and foramen magnum‐to‐cranium distance (FCD) for predicting poor neurodevelopmental outcomes in fetuses with a small head circumference (HC). Methods This retrospective observational study included 39 fetuses with HC < −2 standard deviations (SD) and 592 prospectively collected

Conjugative DNA transfer is enhanced by plasmid R1 partitioning proteins

Frontiers in Molecular Biosciences, 2016
Bacterial conjugation is a form of type IV secretion used to transport protein and DNA directly to recipient bacteria. The process is cell contact-dependent, yet the mechanisms enabling extracellular events to trigger plasmid transfer to begin inside the

Expression and functional characterization of the Agrobacterium VirB2 amino acid substitution variants in T-pilus biogenesis, virulence, and transient transformation efficiency. [PDF]

PLoS ONE, 2014
Agrobacterium tumefaciens is a phytopathogenic bacterium that causes crown gall disease by transferring transferred DNA (T-DNA) into the plant genome. The translocation process is mediated by the type IV secretion system (T4SS) consisting of the VirD4 ...
