Calf scour

Calf scour is caused by Escheria coli. There are lots of serovars of the bacteria. K99+ is one of the important serotype causing calf scour. Improper feeding, high fat containing diet, colostrum deprivation, overcrowding, improper housing, bad hygiene and weather, physical and nutritional stress and status of the dam are some of the predisposing factors. Enterotoxic effect: enterotoxin action, Enterotoxaemic effect: toxin absorbed by intestine and acts elsewhere, Septicemiac form:  extra intestinal location of the toxin.

Streptococcus infection

Strangles is also known as “adenitis equorum” and “distemper”. It is an upper respiratory tract infection accompanied by purulent adenitis of horses caused by Streptococcus equi. An obligate parasite of horses which rarely affect other animal. Most common in young horses.
Purpura Haemorrhagica is characterized by red spots on skin and mucous membranes (such as the gums) caused by bleeding from the small blood vessels under the skin, along with swelling (oedema) of the limbs and around the head. It occurs sporadically and is more common in younger animals. It is often fatal.
Streptococcal mastitis is caused by Streptococcus agalactiae, S. dysagalactiae, and uberis main pathogen in streptococcal mastitis. It is contagious disease of cattle. Obligate parasite of bovine mammary gland. Transmitted from cow to cow by means of milker’s hands or contaminated milking equipment.
Cervical lymphadenitis of pigs is also known as swine strangles and jowl abscess occur in the lymphnodes of pigs. Caused by Streptococcus porcinus. Haemetogenous spread occurs causing abscess in other parts of body or streptococcal endocarditis or meningitis.
Streptococcal meningitis in pigs is a specific infection of young pigs caused by Streptococcus suis. Infection may be subclinical or result in pharyngitis and cervical lymphadenitis. Septicaemia may develop with localization of the organism in the meninges and joints. This lead to fibrinopurulent meningitis and polyarthritis.

Haemorrhagic septicemia

Haemorrhagic septicemia is also known as, “Septicemic pasteurellosis” and “Barbone”. Acute infection of cattle, buffalloes, sheep and goats. It is caused by Pasteurella multocida serotype B and occasionally D and E. The disease mainly occur during the rainy season and causing morbidity and mortality between 50-100%.
In experimental infections with lethal doses, cattle or buffalo develop clinical signs within a few hours and die within 18 to 30 hours. In natural infections, the incubation period is usually 1–3 days but some animals can carry the organism for varying periods without symptoms.

Clostridial Diseases

Black’s disease is essentially an intoxication caused by Clostridium chauvoeiand Clostridium novyi produced by exotoxins, and its development requires a combination of circumstances. Occurs in sheep and cattle (1-2 year), rare in pigs with fluke infestation.
Malignant edema is acute noncontagious disease cause by Clostridium Septicum characterized by severe intoxication, fever, inflammatory edema and subcutaneous swelling in the infected muscles become deep red (dark) and bloody gelatinous fluid accumulation in the body cavities, not noted with Clostridium chauvoei In sheep, in which the disease is named Braxy, Clostridium septicum invades the mucosa and submucosa of the abomasum, by eating frozen food where it multiplies, producing toxin that leads to sudden death.
Bacillary haemoglobinuria is an acute, contagious, toxaemic disease caused by Clostridiumhaemolyticum (Clostridium novyi type D). It affects primarily cattle but has also been found in sheep and rarely in dogs.

Black quarter

Black quarter is an acute infectious disease of cattle and sheep manifested by severe inflammation of the muscle with high mortality. It is caused by Clostridium chauvoei. The organisms of blackleg are most commonly found in the soil and intestinal tract of cattle, sheep, and other ruminants. In sheep the agent is transmitted through wounds at shearing, docking and castration and during lambing in ewes.
