Forty-five claw lamed cows with pododermatitis circumscripta, hyperplasia interdigitalis, and dermatitis verrucosa were treated surgically through resection of necrotic tissues, currettage, antibiotics application, and compressive bandage, under retrograde intravenous regional anesthesia of claw. At 7 days postoperation were showed lameness score 0, absense of swelling of extremitis, without fistulation and purulent exudate in wound. Mean duration time of action of local anesthetic drug was 75 minutes and mean operation time for treatment of pododermatitis circumscripta, hyperplasia interdigitalis, and dermatitis verrucosa was 35 minutes, 20 minutes, and 21 minutes, respectively.

Fifteen dogs with superficial pyoderma were investigated clinically. Dermatological signs were mainly consisted of papule (66.6%), pustule (86.6%), epidermal collrarette and patchy (40%), and hyperpigmentation (53.3%). Distribution of skin lesion were consisted of back (35.5%), abdomen (29.0%), axillary (6.4%), leg (3.2%), neck (3.6%) and foot (16.1%), respectively. In pustular cytology PMN cells and cocci were examined. Cephalexin was very effective antibiotics on superficial pyoderma at administration of 30mg/kg bid P.O.for 3 weeks. Hyperadrenocorticism and atopy were diagnosed as a primary cause on pyoderma in 2 dogs.

Staphylococcus aureus is one of most prevalent intramammary pathogens and have characteristics which are not easily eradicated. Recently, to understand the sources and transmission of S aureus, many studies have focused on the subtyping of field isolate. This study was preformed to investigate the distribution pattern and characteristics of the isolates using phenotyping and genotyping. Samples were collected from milk of each udder, cow bodies (perianal region, vagina, tail, udder skin, sole) and environment (floor, liner, milker's hand, water, towel, insect) from 6 herds located in Kyung-gi province. Forty five strains of S aureus were isolated from 3 dairy herds (A, B, C) and were typed by hemolytic pattern, antibiotic resistant pattern, enterotoxin typing and PCR-based DNA fingerprinting. Slime productivity was also compared by each subtype to examine potential infectiousness. Of 45 strains, 41 were isolated from milk samples and 4 were isolated from liners. No strains isolated in the bodies and environment. Forty five strains isolated were classified as 18 subtypes by phenotyping and genotyping. There was common subtype between A and B herd, but the subtype of C herd showed different pattern. Among predominant subtypes, 60% of S aureus strain isolated from A and B herd showed subtype I and 50% of S aureus strain isolated from C herd belong to subtype VI and XII. Neither somatic cell count (SCC) nor slime production was significantly different between predominant and minor subtypes. In summary, the study revealed that liners play more important roles in the mode of transmission than enmironmental sources. Several subtypes can be found in a herd, only a few subtype, however, was largely associated with the majority of infection.
