Bacteria were also closely associated with fresh isolates of S. nodorum obtained from artificially and naturally infected field material. Although a range of bacteria was isolated, only one type of bacterium was found to be associated with each isolate of S. nodorum. In co-inoculation studies with pycnidiospores of the fungus on detached leaves, some of the bacterial isolates significantly increased the pathogenicity of the fungus, particularly Xanthomonas maltophilia, Sphingobacterium multivorum, Enterobacter agglomerans and Erwinia amylovora. Evidence is presented indicating that one of the ways that the ' helper bacteria ' may assist in the establishment of infections is by the production of lipases that were not detected in germinating fungal spores.

The objective of this study was to determine the relationship of anti-Müllerian hormone (AMH) to ova production in various breeds of cattle in an embryo transfer program. Various factors that were evaluated included breed type, age, weight, body condition and flush history as to their influence on total ova recovery. The superovulation regimen called for CIDR (Controlled Internal Drug Release) insertion and a 2 cc injection of Combo (25 mg progesterone and 1.25 mg of estradiol per mL (2 cc IM injection)) on day 0. Day 4, FSH treatments were initiated in both AM and PM with decreasing amounts over the next four days. Day 6, along with FSH, prostaglandin was given in the AM and PM. On Day 7, a final FSH injection and CIDR removal were done in the AM. This resulted in estrus and AI on day 8 and collection of ova on day 15. Results were drawn from analyzing 369 animals;
