Transcript of Organ:- Chest cavity Lesions:-
Organ:- LungLesions:-Most of the pleural surface covered by abundant fibrin and fibrous tissue
DD:- CBPP
Organ:- Chest cavityLesions:-Large sheets of fibrin cover the costal and diaphragmatic pleura, and form pockets containing straw-colored fluidDD:- CBPP
Organ:- Costal ribsLesions:-There was a thick plaque (adhesion) of fibrous tissue on the costal pleura.DD:- CBPP
Organ:- LungLesions:-Interlobular septa are markedly thickened by fibrous tissue, and also contain small depressions (air pockets = emphysema). Lobules are reddened and wet (congestion and edema)DD:- CBPP
Organ:- Heart Lesions:-The pericardial sac contains abundant turbid fluid DD:- CBPP
Organ:- Bovine carpus
Lesions:-
There was abundant
fibrin within the
synovial space and
on the synovium,
and articular
cartilages contain a
few small erosions.
DD:- CBPP
Organ:- Lung
Lesions:-
Presence of
Fibrinous
exudates in the
pleura.
DD:- CCPP
Organ:- Carpal joint
Lesions:- Haemorrhage on
the synovial membrane
with periarticular edema
in the carpal joint.
DD:- Contagious agalactia
Case History
This cow was suddenly
found dead with:
1. Unclotted bloody
discharge from all
body orifices,.
2. Incomplete rigor
mortis.
3. Rapid distension of
the carcass with
gases.DD:- Peracute anthrax
Case History
This zebra was found
dead (after 3 days of
suffering from a rapid
disease onset) with:
1. Unclotted bloody
discharge from all
body orifices.
2. Incomplete rigor
mortis.DD:-Acute
anthrax
HorseLesions:- Presence of cutaneous nodules (white) on the hind legs.DD:- Glanders
Organ:- LungLesions:- Presence of firm, rounded miliary
nodules on the lung paranchyma.DD:- Glnaders
Organ:- Equine
head
Lesions:-
Mucopurulent
discharge came
out from both
nostriles
DD:- Strangles.
Organ:- Head of equine
Lesions:-Hot painful abscesses of the lymph nodes of the throat. DD:- Strangles
(Distemper).
Organ:- Equine head
Lesions:- Sub-maxillary lymph nodes appear enlarged with present ofyellowish creamy Pus.DD:- Strangles
Organ:- LungLesions:-
Multiple pyo-
granulomas are found
in the lungs.
DD:- Rhodococcus equi
infection
Organ:- Kidney of foal Lesions:- (A): The indistinct white foci in the cortex of the kidney are areas of acute infection and contain the bacterium.(B): Infiltration of nuetrophils within glomeruli and tubules and obliterated glomeruli by presence of basaphilic structure ( bacterial colonies). DD:- Septicemia due to Actinobacillus equuli.
Case history:-An affected horse moves with a stiff-legged gait, often with the tail held out stiffly and the ears pricked. As the disease progresses the muscles become very rigid and stiff that the horse may fall and not be able to get up again.
DD:- Tetanus
Organ:- Eye of foal
Lesions:-
The prominence of the
foal's third eyelid.
DD:- Tetanus
Organ:- Small intestine of pig
Lesions:- The mucosa was congested and covered by a large yellowish-brown casts of fibrino-necrotic exudate (diphtheritic pseudomembrane).DD:- Salmonellosis
Case history:- A 48-year-
old man presents with
draining sinus tracts on
his elbow (arrows). The
drainage resembles small
grains of sand.
DD:- Botryomycosis
OrganSkin biopsy obtained from human with hard fibrous nodules on his arm.
Lesions:-1- Basophilic concretion surrounded
by an eosinophilic rim is seen 2- The concretion consists centrally of
basophilic granular material (bacterial colonies) and peripherally of a homogenous eosinophilic material oriented in radiating club-shaped bodies (rosettes-shaped) about the bacterial colonies.
DD:- Botryomycosis
