Q

Most effective treatment for leptospira infection in growing pigs

A

Long term use of tetracyclines. Vaccinations are usually only used in the breeding herd where bacterins, containing the appropriate serovar, can reduce the prevalence of infection and leptospirosis-induced abortions. Depopulation or euthanasia is not necessary as in growing pigs the clinical signs are not life threatening (leptospirosis-induced abortions is not a concern). Fluoroquinolone antibiotics are not useful against leptospirosis. Besides tetracycline antibiotics, other effective antibiotics include tylosin, erythromycin, and penicillins.

Q

Synovial gout or articular gout cause and treatment

A

The disease occurs when uric acid crystallizes in the synovium and causes lameness. Allopurinol is used to decrease uric acid formation. The underlying pathophysiology is not completely understood, but renal disease is found in many affected birds; treatment generally consists of a low-protein diet, allopurinol, and addressing underlying renal disease.

Q

Carcinoma

A

These tumors come from epithelial cells including cells of glandular tissues such as salivary glands, mammary glands, and cells lining most tissues including squamous cells or transitional cells. The cytologic appearance is that of COHESIVE CLUSTERS of cells. Here, you can see some of the tight cellular junctions in the cluster which is typical. Cells are often polygonal in shape.

82
Gangrenous mastitis is caused by which two organisms?
Mannheimia spp. and Staphylococcus aureus. Occurs sporadically during the first 3 months of lactation. It is generally associated with poor milk supply related to ewe undernutrition and over vigorous suckling by the lambs. Despite antibiotic and supportive therapy, the prognosis is grave, and gangrenous udder tissue eventually sloughs leaving a large granulating surface with superficial bacterial infection. The granulation tissue continues to proliferate over the coming months. These ewes are unsuitable for breeding stock. The infected granulation tissue and resultant drainage lymph node enlargement would result in carcass condemnation (and raise genuine welfare concerns). The fleece is very poor because growth has occurred during this period of illness. The ewe should be euthanized for welfare reasons at first presentation. Control measures include ensuring ewes are well fed. Concentrates should be supplied to ewes and lambs when pasture is poor. No ewe should be expected to rear triplets. Teat lesions should be identified and treated with topical antibiotics.

Thoroughpin (equine)
Effusion of the tarsal shealth (shealth of the deep digital flexor)
97
Haemoproteus
Diagnosis of Haemoproteus infection is made by microscopic examination of a peripheral blood smear. Haemoproteus gametocytes partially encircle the nucleus of erythrocytes forming a "halter-shaped" appearance. Haemoproteus gametocytes often occupy over one-half of the erythrocyte cytoplasm with little displacement of the host cell nucleus as seen here. The haemoproteus life cycle involves a blood sucking insect for transmission (mosquitos, lice, and culicoides). The infection often does not cause clinical signs but may cause an enlarged gizzard, spleen, liver, or kidney. Treatment of choice is the antimalarial drug, chloroquine.
