Furthermore, considering the higher proportion of toxigenic versus non-toxigenic C. ulcerans compared with C. diphtheriae, we found that seven out of nine analyzed C. ulcerans isolates carried a putative PAI which is completely different to the known prophages encoding DT.
Additionally, we identified a novel, putative PAI which could potentially be subjected to horizontal gene transfer and thereby explain the high fraction of toxigenic C. ulcerans.
The esp gene is located on a large pathogenicity island (PAI), which is between 64 and 104 kb in size.
I saw a red neon sign reading Pe Pai, which I assumed to be a Chinese transliteration.
E. faecalis strain UW3114 harbouring a variant of the E. faecalis PAI which contains the esp gene, and an erythromycin resistance plasmid (pLG2), was used as donor.
A further improvement can be achieved by the use of a Ge pre-amorphization implant (PAI), which also removes the stable extended defects observed after high-dose B implantations.
H. pylori encodes several virulence factors, the most well-described being the cag pathogenicity island (PAI), which encodes a type IV secretion system and the effector protein CagA, and the vacuolating cytotoxin VacA, which induces morphogenic changes of the host cell [3] [5].
The MAAS consists of items all focusing upon feelings, attitudes and behaviors towards the fetus, in contrast to scales such as the MFAS and PAI, which contain a number of items related to the pregnancy state and motherhood role.
Disease associated H. pylori strains have been divided into two types, type I being those that carry the cag pathogenicity island [ 8] (cag PAI), which has a foreign species origin, and are associated with more severe disease.
Photoacoustic imaging (PAI), which is a novel hybrid imaging modality owning high optical absorption contrast and good ultrasonic resolution, has been shown as a promising tool for vascular imaging by means of laser-induced ultrasound [ 11, 12]: In PAI, a short pulsed laser source is used to excite a biological sample (e.g., tendon).
Virulent strains of the bacterium contain a genetic element called the CagA pathogenicity island (CagA PAI), which encodes components of a Type IV secretion system and the virulence factor, CagA [5].
