strangles can be passed on through touching a horse with it and then touching another.Horse with strangles should be isolated.They will have thick snotty noses,will struggle to eat,and then develop abcesses under the chin area which are not pleasant to deal with!!These need to be hot fomented to bring out the pus.One person should deal with these horses and any clothes,body,brushes rugs buckets ect should bekept seperated and be disenfected asap.
many horses are treated with antibiotics but this can cause bastard strangles (excuse the rude word but this is the name) which causes abbcesses to form inside the horse and can be life threatening.
there is a newsletter on the bhs updates page www.bhs.org.uk
but currently bhssite is proving difficult to log on to - keeps asking for a network password.
hope this helps
