Possible degradation in the effectiveness of antibiotics in the treatment of human diseases

There are a few infections that can be passed on from cats + dog to
people. Dog + cat bites are notorious for producing wounds with
Pasteurella sp. Its something like 50% of wounds from a dog bite + 75%
of wounds from a cat bite will be infected with Pasteurella sp. There
was an article in a fairly recent copy of the New England Journal of
Medicine that did a survey on animal bites. (They discounted a tiger
bite for some reason!!)

As for Toxoplasma .. a large percentage of cat owners will have
antibodies to Toxoplasma. They will have become infected at some stage -
usually related to litter trays - and will only feel as if they have a
slight cold. They wont realise that they have been infected. (I have 2
cats + have antibodies to it! lol) One of the main problems with
Toxoplasma... as well as a danger to the foetus in pregnant women... is
the risk to AIDS patients.

If the +ve serology is found early enough in HIV patients - they can be
treated with Septrin. Toxoplasma can cause brain abscesses and 20% of
Toxoplasma brain abscesses have negative serology. 

So.... guess who's just been on a course!!!!

Anne :o)

Ok - I'm going to try + send this posting just once!!! Wish me luck!
