Infection by Brucella melitensis or Brucella papionis modifies essential physiological functions of human trophoblasts.

Brucellosis is a zoonosis caused by bacteria of the Brucella genus. In ruminants, brucellosis causes abortion, followed by chronic infection and secretion of bacteria in milk. In humans, it usually presents as flu-like symptoms, with serious complications if untreated.

A spp. Isolate from a Pac-Man Frog () Reveals Characteristics Departing from Classical Brucellae.

are highly infectious bacterial pathogens responsible for brucellosis, a frequent worldwide zoonosis. The genus has recently expanded from 6 to 11 species, all of which were associated with mammals; The natural host range recently expanded to amphibians after some reports of atypical strains from frogs. Here we describe the first in depth phenotypic and genetic characterization of a strains isolated from a frog.
