The reasons for shed spread are mundane.
Based on shedding, systemic spread, and histopathology, the live-attenuated S. typhimurium strain CVD 1921 appears to be safe and well-tolerated in the nonhuman primate model, including chronically SIV-infected rhesus macaques.
Most strains of AIV are designated low pathogenic (LP) and cause minimal illness in chickens, as well as in wild waterfowl and shorebirds, but infection results in high levels of virus shedding, efficient spread among susceptible hosts, and perpetuation of the agent.
In contrast, spatiotemporal analysis indicates that absence of shedding impairs spread of prion pathology.
24 While most antibiotics encourage MRSA shedding and spread between patients, exposure to these particular antibiotic classes are more likely to be associated with increasing MRSA acquisition rates.
But for nearly a decade, Mr. de Vaul has been housing dozens of homeless men and women in a farmhouse and a collection of tents, trailers and sheds spread around his 72-acre ranch here on the outskirts of this city in central California.
Doubles from £140 B&B, 01397 722235, glenfinnanhouse.com What started out in the 1970s as a coffee shop and exhibition space in a boat shed, has spread along a row of cottages and now comprises a restaurant, bookshop, cafe-bar (and performance) area with bedrooms upstairs.
There was limited viral shed and spread following these acute infections.
In response to this action, amid rumors that blood had been shed, alarm spread through the countryside as far as Connecticut and beyond, and American Patriots sprang into action, fearing that war was at hand.
In terms of viral evolution, the CPV ancestor had only to gain the ability to infect the gut in order to be shed and spread in the dog population (26 ).
