Romania, L. Tudor
Slaughter Horse
Ante mortem
Anthrax (Febris carbunculosa, infect.
Disease through meat)
Fever, faster breathing, "heart whacking"
mucosal congestion, muscle tremor.
Lameness is often noted no obvious cause.
Localized swelling are found in the ventral
region of the abdomen and thorax, neck
times, along the jugular veins and thoracic
cavity, the limbs, as well as the perianal
region.
Post mortem
Connective tissue edema;
Renal box associated with accumulation of
significant amounts of reddish exudates in
the abdominal cavity.
Edema pasty, soft, yellowish or reddish.
Spleen may be normal or, often, is the seat
of outbreaks prominent red - purple
appearance infarctiform (carbuncles). In
rare cases, the spleen may be enlarged,
soft, red - blackish, semi fluid the section.
Abdominal/chest lymph nodes enlarged and
red - black.
Major organs (liver, kidney, heart) are
congested and dystrophic and lungs
congested and edematous.
Blood clots and has no red - blackish
Leptospiroses (Leptospiroses)
Liver, jaundice generalized lesions
Glanders (Malleus)
Nasal discharge usually unilateral, initial
mucosal then lactescent slightly yellowish
and sometimes purulent;
Ulcerative nodules;
presence of previous respiratory tract and
skin (chancre glanders) and inflammation
of submaxillary lymphnodes and lymph
vessels in the affected region
Skin lesions (abscesses and ulcers
associated with swollen glands and
inflammation of the lymphatic vessels, the
path which glanders ulcers occur in various
stages of training and covered with a
2
yellowish liquid called "oil farcine")
nodular laryngotracheitis and colitis (ulcers
crateriform aspect, the form of withdrawal
stars of mucosal scars);
Lungs lesions that externalize or by nodular
form (isolated or compact granulomas that
may undergo the phenomenon of "melting"
purulent and its deleted content bronchial
lumen, creating caves) or by lobular foci of
exudative bronchopneumonia.
Metastatic liver (lumps in different
developmental stages),
Spleen (nodules and ulcers which open into
the abdominal cavity, causing purulent
peritonitis),
Salmonellosis
Enteric septicemia - frank salmonellosis or
abortion.
Clinical septicemic salmonellosis can evolve
into hyperacute, acute septicemic or into
prevalence and subacute or chronic
digestive disorders with general symptoms
poorly
expressed
but
localized
inflammatory processes necroticopurulente
(arthritis, tenosynovitis, abscess, etc.).
Tetanus
Skeletal muscle contractions. These start
normally, the muscles of the head and
rapidly goes into other body regions. Can
be found highlighting the third eyelid (the
first clinical symptom equine), impaired
swallowing, saliva leaking in corners,
trismus, stiff ears, nostrils " the trumpet",
"sardonic laughter" curved neck ortotonus,
opistotonus , emprostotonus, belly sucking,
flank rope obvious, rigid limbs removed
("buck"),
walking
"like
needles"
hyperexcitability to external factors (light,
noise touch, drafts), rapid and violent
contraction of a muscle or group of muscles
throughout that acquires hardness of the
wood ("tetanus crisis"), cyanotic mucous
membranes, sweating, colic, cessation of
rumination, flatulence .
High temperature (during the first 3-4
hours after death can reach 42-45 ° C), so
that the meat is very slow cooling, and
early muscle rigidity and high installed.
Decubitus wounds, while the tetanigene
are sometimes very small, insignificant or
being healing.
The areas are degenerative muscle rupture
and haemorrhage fascicular (giving meat
congestive aspect) in heart, liver and
kidneys - dystrophic lesions, hemorrhages
on serous and heart, intestinal bleeding,
and lungs - congestion, edema or
pneumonia bodies foreigners. In the CNS,
especially in the spinal cord are found
hyperemia,
hemorrhage
and
serous
infiltration of the meninges
