Bulldog Health:Pathogen evolution and disease emergence in carnivores.
Emerging infectious diseases constitute some of the most pressing problems for both human and domestic animal health, and biodiversity conservation. Currently it is not clear whether the removal of past constraints on geographical distribution and transmission possibilities for pathogens alone are sufficient to give rise to novel host-pathogen combinations, or whether pathogen evolution is also generally required for establishment in novel hosts. Canine distemper virus (CDV) is a morbillivirus that is prevalent in the world dog population and poses an important conservation threat to a diverse range of carnivores. We performed an extensive phylogenetic and molecular evolution analysis on complete sequences of all CDV genes to assess the role of selection and recombination in shaping viral genetic diversity and driving the emergence of CDV in non-dog hosts. We tested the specific hypothesis that molecular adaptation at known receptor-binding sites of the haemagglutinin gene is associated with independent instances of the spread of CDV to novel non-dog hosts in the wild. This hypothesis was upheld, providing compelling evidence that repeated evolution at known functional sites (in this case residues 530 and 549 of the haemagglutinin molecule) is associated with multiple independent occurrences of disease emergence in a range of novel host species.

The Original Bulldog Club ->> The Bulldog Club of Milan ->>To promote and encourage the Breeding of Pure Bulldogs in all of the World, but more especially In the provinces of England, to Ireland, and in Scotland, in Italy, in Lombardy and in Milan.
Honorary President, Ever and Forever, Mrs. D.N. and Mr. Les Thorpe. Bulldog Club, creato per celebrare la incredibile nascita proprio a Milano, per merito esclusivo di Tuffnuts Bulldogs, in collaborazione con il The Bulldog International Research Center e con Ocobo Show Bulldogs, di quelli che, secondo i più profondi studi mondialmente dimostrabili, risulterebbero essere i più diretti discendenti e, quindi, i legittimi eredi di Rosa, il capostipite della Razza Bulldog, con genealogia integralmente inglese, Lincolnshire, Tuffnuts Ocobo. Il Club si è formato, infatti, nel Dicembre 2004 alla nascita di Tuffnuts Snow Angel Tuffnuts, dedicata al Maggiore L.A. Jackson ed a Dr. Les Cotton, il secondo Original Pure Breed Bulldog, nato a Milano ed in Italia dopo Tully, nato nel 2000, sempre nell ' Allevamento Tuffnuts Snow Angel. Per supportare la razza e tutti coloro che possiedono un Bulldog Inglese. Cucciolate disponibli, affidamento bulldogs, problemi di salute, riproduttori disponibili, etc..Il primo Club che si pone l'obiettivo di selezionare ed allevare anche il Bulldog Originale di Razza Pura, come era fino all' inizio del 20° secolo, con una genealogia completamente inglese, discendente dai più famosi Campioni della Storia.
