Mastitis caused by Klebsiella spp is an emerging issue associated with contaminated environments, often with poor response to therapy. This case report highlights 42 cows with 50 cases of clinical mastitis caused by Klebsiella spp. Eight cases of clinical mastitis were from 4 cows with repeat cases. The mean days-in-milk (DIM) at diagnosis was 135; 38% of cows were within the first 100 DIM. Cows diagnosed with mastitis had a 65% decrease in milk production. Severity scores assigned to each case were 24% mild, 33% moderate, and 43% severe. The majority of cows were either culled (38%) or euthanized (19%) as a result of the mastitis. Many of the cows that developed clinical mastitis had been good producing animals with low somatic cell counts prior to the case. Environmental control and cow hygiene are key to prevention of mastitis.

An outbreak of urolithiasis occurred in a small beef cattle feedlot feeding a total mixed ration containing cracked com, com gluten, gluten balancer, hay and di- atomaceous earth. A1100 lb (500 kg) steer was presented to the Iowa State University Veterinary Diagnostic Laboratory for euthanasia and necropsy. Clinical signs included frequent tenesmus, evidence of abdominal pain, regurgitation and labored breathing. Serum chemistry revealed elevated BUN (160 mg/dl), creatinine (28.9 mg/ dl), creatine kinase (2253IU/L), and an inverted calcium- to-phosphorus ratio of 0.8. At necropsy, complete obstruction of the urethra with calcium phosphate (apatite) calculi was present. Based on the clinical pathology and extensive tissue damage in this animal, the prognosis was poor if surgical treatment had been elected.Analysis of the total mixed ration revealed a calcium-to-phosphorus ratio of 1:1. This case highlights the importance of a prompt diagnosis of urinary calculi in symptomatic animals, and evaluation of the ration for possible mineral imbalances.

region and contains the deepest wells drilled in North America. The region has had a long sedimentary-tectonic history reaching back to the Proterozoic and was the site of an early Paleozoic basin. The present shape of the Anadarko basin, however, was developed in late Paleozoic times as a result of the uplift of the Wichita Mountains. COCORP seismic reflection profiles show at least 8 to 9 km (5 to 5.6 mi) of overthrusting northward, and the Anadarko basin was developed as a result of f lexural bending of the lithosphere due to this shortening. Down-warping of the basin can be observed to extend for over 300 km (185 mi) northward, indicating a high flexural rigidity (Te > 40 km [25 mi]). However, nearer the Wichita front, the basin steep ens rapidly as the post-Mississippian sediments thicken to over 20,000 ft (6,100 m). The shape of the bending is such that it can not be explained by the use of a constant rigidity elastic plate model. We have modeled the post-Mississippian development of the Anadarko basin as the result of flexure of an elastic-plastic plate due to vertical and horizontal loading caused by the Wichita Mountains. Implications of these results for the development of the Anadarko basin and the mechanical properties of continental lithosphere will be discussed. This work attempts to establish the age and chronologic sequence of mid-Cenozoic tectonic events in Trans-Pecos Texas through the use of radiometric dates, and new or revised struc tural, lithostratigraphic, and vertebrate biostratigraphic infor mation. Late Mesozoic to early Cenozoic Laramide faulting, folding, and jointing superimposed on older trends, established the fabric governing younger structures. Late Oligocene events, occurring about 28 to 26 m.yB.R, include right-lateral divergent wrench fauhing, local compression, and the last episodes of silicic intrusion-extrusion.
