A new, symptomless virus was identified in blueberry. The dsRNA genome of the virus, provisionally named Blueberry latent virus (BBLV), codes for two putative proteins, one without any similarities to virus proteins and an RNA-dependent RNA polymerase. More than 35 isolates of the virus from different cultivars and geographic regions were partially or completely sequenced. BBLV, found in more t...

Two methods to induce a symptomless infection of crown rot (Phytophthora cactorum) in stolons of three strawberry (Fragaria×ananassa) cultivars were evaluated. Spraying a 10−4 ml zoospore suspension was the most effective method, producing a mean infection rate of 12%. Meristem cultures were subsequently established from all of the inoculated stolons and tested eight weeks later for the presenc...

A symptomless 58 year old man had an eosinophilic granuloma of the lung that presented as a solitary pulmonary nodule rather than the usual diffuse reticulonodular shadow on the chest radiograph. Only one previous case presenting in this way has been described.

A patient with symptomless Paget's disease of the bone, suddenly developed multiple osteogenic sarcoma. Obstruction to one jugular vein led to increased intracranial tension and a perforation developing in the orbital plate of the frontal bone led to uni-. ocular symptoms and signs. With this, we believe hitherto unrecorded complication, he also exhibited some of the well known'complications of...

Disease severity was recorded 2 weeks after planting when seedlings were still at the primary leaf stage. In all of the rows planted with inoculated seeds, some of the plants were symptomless and others had leaf spots and puckering symptoms characteristic of bacterial brown spot. No difference in type or severity of symptoms was noted in any of the treatments. None of the treatments resulted in...
