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

(Distemper).

Organ:- Equine head

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.

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
