As

part

of a

systematic study

of hemostasis in the

pig,

we studied the

properties

of

platelets

in that

species.

After

briefly describing

their basic role in the hemostatic

mechanism,

we examined the volume and

density

distribution of

platelets

in the

pig, comparing

our results with those obtai- ned in man.

A

serological grouping

of 147 7 Escherichia coli strains, isolated from 52 newborn

piglets

and

from 105

piglets

at

weaning

revealed that

3/1

of the strains were

enteropathogenic.

In the new

born

piglet,

the strains isolated were

mainly

oI-j9 Ii 9I, K 8S ac and in the

piglet

at

weaning, by

order of

frequency :

Colistine

excepted,

all strains showed a considerable

lowering

of

scnsitivity

towards all cur-

rently

used antibiotics.

Vaccinations made

peroral

or from

specific

fractions of enterotoxines seem to be

promissing.
