To assess the growth of the fetus and to see
which way it is lying in the uterus.
To detect diabetes or pre-eclampsia.
To detect developing pre-eclampsia.
Blood tests (at
some visits only)
To lookfor anaemia and, in combination
with ultrasound scanning, to assess the risk
of fetal abnormalities such as neural tube
defects or Down’s syndrome. A test to
screen for diabetes mellitus in the mother

The woman is also advised on general

Anthracosis is a lung
disease caused by inhalation of large
amounts of coal dust over many years.
A serious bacterial infection of livestock
that occasionally spreads to humans.
The most common form of the infec-
tion in humans is cutaneous anthrax,
which affects the skin. Another form,
pulmonary anthrax, affects the lungs
and is potentially fatal.
Anthrax is caused by BACILLUS ANTHEACIS.
This bacterium produces spores that can
remain dormant for years in soil and
animal products and are capable of
Animals become infected by grazing
on contaminated land. Infection can
occur in humans via a scratch or a sore
if materials from infected animals are
handled. Pulmonary anthrax occurs as a
result of inhaling spores from infected
SYMPTOMS AND TREATMENT
In cutaneous anthrax, a raised, itchy,
area develops at the site of entry of the
spores, progressing to a large blister and
finally a black scab, with swelling of the
surrounding tissues. Cutaneous anthrax
is treatable in its early stages with
Without treatment, infection
may spread to lymph nodes and the
bloodstream and may be fatal.
