I Think yes, according to the OIE list of diseases

Yes, B. melitensis bv3 was recorded twice in wild animals in Egypt. One in rat and one in Fish. You can find all Information about that in that Review ( animal brucellosis in Egypt. Wareth et al 2014

Yes, we have signalled B melitensis bv2, and bv3 from a foci n Alpine ibex in Italy . Also alpine chamois in France has been on occasion reported to be infected. We used also lung tissue extract in spote of bllod sera for serological diagnosis in hunted or found dead wild animal

Yes,

Several cases identified in France in Chamois (Rupicapra rupicapra) with important signs (arthritis, uveitis, orchitis) in the past. These cases disappeared with he eradication of B. melitensis in domestic ruminants in 2003. However an important reservoir of B. melitensis has been identified in 2012 in a well-delimited mountain massif in Alpine ibex (Capra ibex) in southeastern French Alps. Secondary cases were observed in 2 chamois and infection has been transmitted to domestic cattle (one farm). This reservoir was probably created a long time ago when infection was important in local domestic ruminants (cattle, sheep and goats) since the last brucellosis outbreak occurred in the area in 1999. No transmission from this reservoir to domestic or wild species has been observed before 2012. (see attached papers)

I did isolate Brucella melitensis bv. 3 from milk of 24 Alpine Chamoisée goats from Kafr El-Sheikh governorate in the Nile Delta of Egypt. These animals were the remainder of a larger flock (number unknown) imported from France for breeding.  Please find the attached file.

Kamel (1950) isolated 3 cultures of Brucella abortus (mostly biovar 1 ??) from swollen joints of Egyptian Gazelles at the Royal Park in Inshas, Cairo, Egypt.  Dr Hussein Kamel used to work in my lab before I was born.
