Dear MARMAM readers

We are pleased to announce the publication of a new paper on Brucella in
Antarctic seals.

Title: Brucella antibody seroprevalence in Antarctic seals (Arctocephalus
gazella, Leptonychotes weddellii and Mirounga leonina).

ABSTRACT

Brucellosis is a worldwide infectious zoonotic disease caused by
Gram-negative bacteria of the genus Brucella, and Brucella infections in
marine mammals were first reported in 1994. A serosurvey investigating the
presence of anti-Brucella antibodies in 3 Antarctic pinniped species was
undertaken with a protein A/G indirect enzyme-linked immunosorbent assay
(iELISA) and the Rose Bengal test (RBT). Serum samples from 33 Weddell
seals Leptonychotes weddelli were analysed, and antibodies were detected in
8 individuals (24.2%) with the iELISA and in 21 (65.6%) with the RBT. We
tested 48 southern elephant seal Mirounga leonina sera and detected
antibodies in 2 animals (4.7%) with both the iELISA and the RBT. None of
the 21 Antarctic fur seals Arctocephalus gazella was found positive. This
is the first report of anti-Brucella antibodies in southern elephant seals.
The potential impact of Brucella infection in pinnipeds in Antarctica is
not known, but Brucella spp. are known to cause abortion in terrestrial
species and cetaceans. Our findings suggest that Brucella infection in
pinnipeds is present in the Antarctic, but to date B. pinnipedialis has not
been isolated from any Antarctic pinniped species, leaving the confirmation
of infection pending.
