Epidemiological and serological profiles of ocular toxoplasmosis in the municipality of Natal, northeastern Brazil.
[congenital toxoplasmosis]
Toxoplasma
gondii
is
the
main
culprit
in
most
cases
of
infectious
uveitis
,
in
both
acute
and
recurrent
cases
of
congenital
toxoplasmosis
and
acquired
infections
.
The
ocular
toxoplasmosis
was
evaluated
in
patients
at
the
the
reference
unit
in
ophthalmology
,
in
Rio
Grande
do
Norte
State
,
determining
the
risk
factors
,
and
the
epidemic
,
serological
and
clinical
profiles
.
The
production
of
IgM
and
IgG
antibodies
to
T
.
gondii
was
evaluated
by
microparticle
enzyme
immunoassay
(
MEIA
)
.
The
same
patients
diagnosed
with
fundoscopic
alterations
have
been
subjected
to
the
fundus
photography
procedure
.
Of
the
116
patients
with
positive
serology
,
66
patients
had
bilateral
ocular
damage
and
38
patients
showed
a
higher
frequency
of
lesions
of
type
I
.
The
epidemiological
investigation
showed
that
direct
contact
with
cats
,
the
consumption
of
raw
or
undercooked
meat
and
direct
contact
with
soil
are
factors
not
related
to
ocular
toxoplasmosis
development
.
The
characterization
of
the
sample
was
significant
for
patients
aged
31
-
40
years
.
Ocular
toxoplasmosis
is
widely
distributed
in
Natal
and
other
cities
in
Rio
Grande
do
Norte
state
,
with
special
relevance
for
bilateral
lesions
in
56
.
9
%
of
the
patients
assessed
,
the
most
frequent
being
type
I
with
intraocular
disposition
in
the
macula
.
