Treponema Infection Associated With Genital Ulceration in Wild Baboons
The authors describe genital alterations and detailed histologic findings in
baboons naturally infected with Treponema pallidum. The disease causes
moderate to severe genital ulcerations in a population of olive baboons (Papio
hamadryas anubis) at Lake Manyara National Park in Tanzania. In a field survey
in 2007, 63 individuals of all age classes, both sexes, and different grades
of infection were chemically immobilized and sampled. Histology and molecular
biological tests were used to detect and identify the organism responsible: a
strain similar to T pallidum ssp pertenue, the cause of yaws in humans.
Although treponemal infections are not a new phenomenon in nonhuman primates,
the infection described here appears to be strictly associated with the
anogenital region and results in tissue alterations matching those found in
human syphilis infections (caused by T pallidum ssp pallidum), despite the
causative pathogen’s greater genetic similarity to human yaws-causing strains
Urinary tract infection: The role of canine transmissible venereal tumour
The role of transmissible ‘venereal tumours in
the pathogenesis of urinary tract infection in
dogs was investigated in 86 dogs. Fifty-five had
transmissible venereal tumours, and the remaining
31 animals were used as controls. A thorough
clinical examination of the external genitalia was
carried out in each case. In the dogs with transmissible
venereal tumours, the sites of attachment
were recorded. Urine samples were taken
by cystocentesis and the external genitalia
swabbed; the samples were cultured for bacteria
using standard methods. Tumours were found on
the prepuce and other parts of the penis in male
dogs; in bitches they were found in the vagina,
vestibule or the vestibulovaginal junction. Dogs
with transmissible venereal tumours were found
to be at a high risk of having bacteriuria (odds
ratio [OR] = 7.04). Obliteration of the urethral orifice
by the tumour, possibly leading to urine
retention, was thought to be the main reason for
the high incidence of urinary tract infection
among dogs with transmissible venereal tumours.
Long-standing cases of transmissible venereal
neoplasia had a higher chance of becoming bacteriuric
compared with recent cases (OR=29.60).
This study indicates that transmissible venereal
tumour may he a predisposing factor for the
development of urinary tract infection

Serum protein electrophoresis:potential test for use in geriatric companion animal health programmes
Farmer forums for improved food security: Experiences from TARP II SUA Project
Journal of Continuing Education and Extension, 2005; 2(1):18-30Farmer forums under the TARP II SUA, project in Tanzania have demonstrated
fruitful partnership between farmers, researchers and extension agents in
communicating and disseminating innovations and technologies to a wider
audience. Five forums have been held in each of the zones implementing the project.
Some of the themes covered under the five forums include: identification of problems
faced by smallholder farmers, marketing problems for agricultural produce, local
chicken: production and demand, technology adoption from farmers ' perception and
conflicts between crop producers and livestock keepers. During these forums,
participating stakeholders identified and prioritized key issues and problems,
proposed solutions and agreed on respective stakeholders' responsibilities. This
paper provides an overview on the conduct, perceptions, outputs and the challenge ahead
regarding this approach for the development offarmers
