Investigation and control of mastitis outbreaks caused by Pseudomonas aeruginosa in a sheep flock and a goat herd.

Outbreaks of mastitis in a sheep flock and a goat herd caused by Pseudomonas aeruginosa, and their control are described. The morbidity rates of mastitis in a sheep flock and in a goat herd were 18.7 and 18.

Epidemiological and bacteriological aspects of mastitis associated with yellow-jacket wasps (Vespula germanica) in a dairy cattle herd.

The German wasp, Vespula germanica has been observed to injure teats of dairy cows, causing lesions that are associated with clinical and subclinical mastitis. The presence of skin lesions on the teats, caused by the wasps, was recorded in a dairy cattle herd located in the Samaria foothills during July-October 1999. Wasp-inflicted injuries were found in 43.

Effect of the angle of the screw on the stability of the mandibular sagittal split ramus osteotomy: a study in sheep mandibles.

We compared the biomechanical stability of 60 degrees and 90 degrees angles for insertion of screws for fixation of sagittal split ramus osteotomies (SSROs) in 10 sheep mandibles in vitro. After 5 mm advancements, the osteotomies were fixed with screws 2 mm in diameter inserted with a torque control screwdriver at either 60 degrees or 90 degrees to the long axis of bone, in a matched pair experimental design. All specimens were then loaded in a physiological manner and the load-displacement of the osteotomies was recorded.

Wasps are the cause of an increasing mastitis problem in dairy cattle in Israel.

The German wasp Vespula germanica (Fabr.) (Hymenoptera: Vespidae) has been observed to injure dairy cows teats, causing lesions which can lead to mastitis. The number of dairy herds in Israel reported to be affected in this way has increased from five prior to 1989 to 32 from 1989 to 1993.

Facial rhytidectomy approach for treatment of posterior mandibular fractures.

Surgical access to fractures of the ascending ramus of the mandible is limited when standard techniques are employed. A new method using a facial rhytidectomy technique is described, and seven cases treated by this method are presented. The advantage of this technique includes excellent exposure, predictable and safe dissection, inconspicuous facial scar and minimal postoperative complications.
