New insights into the pathogenesis and transmission of : systemic infection in two bottlenose dolphins ().

spp. are zoonotic pathogens that can affect both terrestrial and marine mammals. has been identified in various cetacean species, but only one sequence type (ST27) has been reported in humans.

A Brucella melitensis H38ΔwbkF rough mutant protects against Brucella ovis in rams.

Brucella melitensis and Brucella ovis are gram-negative pathogens of sheep that cause severe economic losses and, although B. ovis is non-zoonotic, B. melitensis is the main cause of human brucellosis.

Weaned piglets: another factor to be considered for the control of Salmonella infection in breeding pig farms.

Field studies on Salmonella infection in suckling piglets are scarce due to the intrinsic difficulties of collecting proper samples (i.e. tonsils or mesenteric lymph nodes), and most of them rely on the analysis of rectal swabs that limit their accuracy.

Phylogeography and epidemiology of Brucella suis biovar 2 in wildlife and domestic swine.

Swine brucellosis due to Brucella suis biovar 2 (bv2) is enzootic in wild boar and hare in continental Europe and may cause major economic losses to the pig industry, mainly in free-ranged pig farms. The high nucleotide identity found among the B. suis biovar 2 isolates has long hindered the full understanding of the epidemiology and the phylogeography of the disease.

Characterization of Salmonella enterica Serovar Typhimurium Isolates from Pigs and Pig Environment-Related Sources and Evidence of New Circulating Monophasic Strains in Spain.

A total of 117 Salmonella enterica serovar Typhimurium and 59 monophasic Salmonella Typhimurium (S. enterica serovar 4,[5],12:i:-) strains isolated between 2008 and 2012 from pig, wild bird, rodent, and farm environment samples from the northeast of Spain were characterized by phage typing, antibiotic susceptibility testing, and multiple-locus variable-number tandem repeat analysis in order to evaluate their phenotypic and genetic relatedness. In Salmonella 4,[5],12:i:-, the most prevalent phage types were U311 (40.

Role of wild bird and rodents in the epidemiology of subclinical salmonellosis in finishing pigs.

Wild birds and rodents may play an important role in the dynamics of subclinical pig salmonellosis, either as the introducers of the bacteria into the farm or as receptors of an infection already established in the farm. We tried to gain further insight into the epidemiology of this infection by studying the phenotypic (i.e.
