Mastitis and other diseases of the goat's udder.

Udder problems of modern dairy goats are similar to those seen in dairy cows. Anomalies of the goat's udder and teats are common, and many may be hereditary. Skin diseases of the udder include viral infections, mange, sunburn, wounds, and staphylococcal dermatitis. There are numerous known causes of caprine mastitis. These include streptococci, hemolytic and nonhemolytic staphylococci, corynebacteria, and mycoplasmas. Diagnosis of mastitis in goats is often difficult, as the udder secretion may remain grossly normal and somatic cell counts in nonmastitic goats are higher than the recognized normal range for cows. The importance of nonhemolytic staphylococcal cultures remains uncertain. Nonhemolytic staphylococci were isolated at the New York State Mastitis Laboratory from 30% of normal halves and from 22% of halves of udders from goats with assorted clinical problems. Treatment and prophylaxis of caprine mastitis closely parallel the standard technique recommended for bovine mastitis.

[Orf: recontamination 8 months after the original infection. Review of the literature apropos of a case].

Frequent in France among domesticated sheep and goats, contagious pustular dermatitis of the sheep is called Orf when it occurs in man. The authors present a case of recontamination in a woman farmer of the Cher department (Central France), who had been bottle-feeding lambs affected with the zoonosis. This 71-year old woman developed papules, then papulopustules on the ulnar aspect of her hands and wrists (fig. 1). Within a few days, these lesions were 1.5 to 2 cm in diameter and surrounded with a severe inflammatory reaction. Two weeks later, the pustules became encrusted. Electron microscopy of a fragment of lesion demonstrated the virus. Cure was observed after 3 weeks. Eight months later, however, lesions identical with the previous ones appeared on the 4th finger and on the median aspect of the right wrist, corresponding to excoriations caused by nibbling from the lambs. The eruption was accompanied with fever which persisted for one month. In this patient's farm, the disease was present for the first time and affected only 2-month old lambs in the form of numerous papulo-pustules located on the lips and later covered by hard and thick scabs. These lesions were also found on the tongue and palate of some animals (fig. 5), preventing them from taking any food. Vaccination resulted in rapid and dramatic regression of the enzootie. From a more general point of view, the clinical features and epidemiology of the disease are described comparatively in animals and man. The differential diagnosis is dealt with at the end of the article. The literature on the subject is reviewed (151 references).

Rationale for topical antibiotics.

Topical antibiotics are under attack by critics who claim that no proof of efficacy exists and that systemic administration is far more effective. In this paper, we review the existing evidence and conclude that topical antibiotics have a place in the prevention and treatment of superficial skin infections. Our own experimental studies showed that topical antibiotics promptly reduce the density of Staphylococcus aureus in secondarily infected chronic dermatoses, associated with clinical improvement. In addition, topical antibiotics were shown to be highly effective in preventing and suppressing experimental S. aureus infections in human volunteers.

Orf. A case report with histologic, electron microscopic, and immunoperoxidase studies.

Orf is an occupational skin disease acquired through contact with infected animals. In humans, orf is usually a self-limited disease that resolves spontaneously within four to 24 weeks. We report a case with multiple lesions of orf, acquired by contact with a wild sheep. The patient was temporarily immunosuppressed by a concomitant viral hepatitis. We reviewed the histologic and electron microscopic findings. Also, we attempted to stain the Parapoxvirus in the skin of the patient, using the immunoperoxidase technique. The antiserum was obtained from sheep immunized against orf. We used lesional skin from sheep infected with orf as a positive control. The negative results of this technique in the patient's skin indicated that Parapoxvirus infecting wild sheep is antigenically different from that causing the disease in domestic animals.
