Acne vulgaris is a prevalent chronic inflammatory disease of the pilo-sebaceous unit characterized by follicular plugging Williams et al. Underlying factors associated with acne lesions are: 1 increased sebum production; 2 inflammation; 3 altered follicular keratinization; and 4 overgrowth with Propionibacterium acnes.

However, over the years it has been difficult to ascertain which of these four factors initiates, promotes or is merely associated with disease state. In particular, to what extent does P.

The mainstay therapies of inflammatory acne include topical and systemic antibiotics, suggesting a microbial contribution. However, these common therapies often show incomplete response, and recurrence is frequent Leyden, As well, systemic acne treatments sometimes possess untolerated side effects, suggesting that more targeted therapeutics would be beneficial.

But does overgrowth of P. Their rationale for pursuing this species level P. Fitz-Gibbons compared P. Skin microcomedone samples were obtained from the pilosebaceous units pores of the nose with Biore strips. Acne and normal cohort had an average age of Biore strips were placed individually in lysis buffer from which DNA was directly isolated. No difference was observed in the relative abundance of P.

Fitz-Gibbons et al. Of the ten most common strain types, the authors found that 3 were evenly distributed between the two cohorts, 6 were more often found in acne patients and 1 was associated with normal skin.

Isolates from the same strain clustered together in the phylogenetic tree based on the full genome sequence, suggesting that 16S rRNA sequences do reflect the evolutionary history of P. The genomes of acne-enriched strains selectively harbor a plasmid and two chromosomal regions that contain genes possibly involved in virulence, adhesion to epithelial tissues or induction of human immune response.

If not.. What they neglect to say is what virus. In Fields Virology Second Edition, for example, it says on pg. So what is it? Polio was originally referred to as infantile paralysis. Though, the diagnostic label was renamed to aseptic meningitis. Source: Fields Virology. The death rate increases with increasing age. Additional milk-borne outbreaks were recognized after this time, but with the development of a vaccine for poliovirus, no outbreaks were reported in the developed world after the early s.

Goyal, pp. Raw milk predominated as the vehicle among the 10 outbreaks recorded through , the last year in which foodborne poliomyelitis is known to have occurred in the United States or other reporting, developed countries. Cliver, pp And I want you to ask yourself two very important questions: 1. When was milk first pasteurized on a massive scale? For that answer you may have to look into the dairy sciences… 2.

Luc Montagnier, who the article references to support its argument that a particle must be isolated in order to establish causation, has specifically rejected suggestions that purification is necessary when isolating viruses here.
