DNA vaccines for bacterial infections

Immunology & Cell Biology, 1997
DNA vaccines are an exciting development in vaccine technology which may have a special role in preventing viral infections and as ‘theracines’ for cancer. Their use in preventing bacterial infections has, by comparison, been less well documented.

The teneurin C-terminal domain possesses nuclease activity and is apoptogenic. [PDF]

, 2018
Teneurins are type 2 transmembrane proteins expressed by developing neurons during periods of synaptogenesis and apoptosis. Neurons expressing teneurin-1 synapse with other teneurin-1-expressing neurons, and neurons expressing teneurin-2 synapse with ...

Wolbachia and DNA barcoding insects: patterns, potential and problems [PDF]

, 2012
Wolbachia is a genus of bacterial endosymbionts that impacts the breeding systems of their hosts. Wolbachia can confuse the patterns of mitochondrial variation, including DNA barcodes, because it influences the pathways through which mitochondria are ...

Comparison of Bacterial DNA Profiles in Mid-Trimester Amniotic Fluid Samples From Preterm and Term Deliveries

Frontiers in Microbiology, 2020
Infection and inflammation are well recognized causes of spontaneous preterm delivery (PTD) (<37 gestational weeks) and adverse infant outcomes. To date, there has been very little investigation into bacterial communities in amniotic fluid using next ...

Detection of airborne Campylobacter with three bioaerosol samplers for alarming bacteria transmission in broilers. [PDF]

, 2011
In an airborne transmission experiment, Campylobacter in the air was sampled by three types of bioaerosol samplers (all-glass impinger AGI-30, Andersen six-stage impactor, and OMNI-3000) in four broiler rooms.
