Uterine leiomyomas in two Vietnamese pot-bellied pigs (Sus scrofa)

Two Vietnamese pot-bellied pigs (Sus scrofa) were euthanatized after they developed abdominal distension. Necropsy of both pigs revealed large myometrial neoplasms and cystic endometrial hyperplasia. Multiple discrete smaller myometrial neoplasms were also observed in one pig; however, distant metastases were not observed in either animal. The tumors were diagnosed as leiomyomas on the basis of histologic examination and immunohistochemistry. This is the first detailed report of uterine leiomyomas in swine, and it is suggested that this diagnosis may become more common as more aging pigs are examined.

The status of Mycobacterium bovis infection in UK wild mammals: a review

Bovine tuberculosis caused by Mycobacterium bovis is a zoonotic infection with a wide range of mammalian hosts. In parts of the UK M. bovis infection in cattle is a persistent problem. The European badger (Meles meles) is implicated in the transmission of M. bovis to cattle, and is widely believed to constitute the most important reservoir of infection in UK wildlife. However, few studies have been carried out on the status of M. bovis infection in other UK mammals. In this review we present information on the incidence and pathology of M. bovis infection in UK wild mammals from both published and previously unpublished sources. Although the evidence does not support the existence of a significant self-maintaining reservoir of infection in any wild mammal other than the badger, there is a clear lack of sufficient data to rule out the involvement of other species. In the light of this and the dynamic nature of epidemiological patterns, further surveillance for M. bovis infection in UK wild mammals, using modern methods of diagnosis, is essential.     

Soil solarization in Greece

Soil solarization (SS) was tested in outdoor conditions in mid Greece by mulching wet soil with transparent polyethylene sheets to examine its effectiveness as a weed control treatment in maize and soybean planted as second season crops. Three or 4 weeks of solarization gave bet-ter weed control than preemergence herbicides and effectively controlled volunteer wheat (Triticum aestivum), Portulaca oleracea, Digitaria sanguinalis, Solanum nigrum, Amaranthus spp. and other weeds. The weed control effects lasted for more than 4 months. In mulched soil the maximum temperature at 7.5 cm depth was generally 7–9°C warmer than in the unmulched soil. Polyethylene thicknesses of 0.015–0.030 mm were equally effective. Plants grown on solarized plots out yielded those on clean weeded hoe treatments. The weed flora present caused maize and soybean losses of 20–48%. These losses would economically justify the use of polyethylene mulches. Solarisation du sol en grece La solarisation du sol (SS) a été testée en conditions extérieures en Grèce centrale, en recouvrant le sol humide avec des feuilles de polyéthylene transparent pour examiner son efficacité comme traitement herbicide sur du ma'is et du soja plantés comme secondes culturesde la saison. Trois ou 4 semaines de solarisation ont donné une meilleure destruction des adventices que des herbicides de pré1evée et ont détruit efficacement les repousses de blé (Triticum aesti-vum), Portulaca oleracea, Digitaria sanguinalis, Solanum nigrum, Amaranthus spp. et d'autres adventices. Les effets herbicides ont duré plus de 4 mois. Dans le sol couvert le maximum de témpérature à 7.5 cm de profondeur a été généale-ment de 7–9°C plus chaud qu'en sol nu. Des épaisseurs de polyéthylene de 0,015–0,030 mm ont é'té pareillement efficaces. Les plantes cul-tivées sur parcelles solarisées produisent autant que celles sur des sols tenus propres par binage. La flore adventice présente a entrainé des pertes de maïs et de soja de 20–48%. Ces pertes justi-fieraient économiquement l'utilisation de films de polyéthylène. Boden-Solarisation in Griechenland In Mittelgriechenland wurde die Solarisation feuchten Bodens, überdeckt mil transparenter Polyethylenfolie, auf ihre Wirksamkeit zur Unk-rautbekämpfung in Mais und Sojabohnen als 2. Kultur der Vegetationsperiode untersucht. Mit 3 oder 4 Wochen Solarisation ließen sich Weizenaufschlag (Triticum aestivum), Portulaca oleracea, Digitaria sanguinalis, Solanum nigrum, Amaranthus spp. und andere Unkräuter besser als mil Vorauflauf-Herbiziden bekämpfen. Die Wirkung hielt > 4 Monate an. Bei der Solarisa-tion lag die Bodentemperature in 7,5 cm Tiefe um 7.9°C höher als bei offenem Boden. Folien von 0,015.0,030 mm Stärke waren gleich wirk-sam. Der Ertrag lag in den solarisierten Parzellen über dem gehackter Parzellen. In den unbehan-delten Parzellen ging der Ertrag um 20.48% zurück, so daß die Solarisation unter Polyethylenfolie ein wirtschaftliches Verfahren ist.     

The effects of ultraviolet-B (UV-B: 290–320 nm) radiation on blister blight disease of tea (Camellia sinensis)

Sunlight is known to reduce the incidence of blister blight disease of tea, caused by Exobasidium vexans . The effects of the ultraviolet-B (UV-B: 290–320 nm) component of solar radiation on the disease and the development of E. vexans were studied in the field in Sri Lanka using UV-screening filter materials held over a commercial crop. Exclusion of UV-B radiation by Polyester, which reduces fluxes in the UV-B region by approximately 75–85%, increased both the number of translucent spots (immature sites of infection) and number of sporulating blisters (mature sites of infection), but it had little or no effect on the sporulation of the pathogen. When basidiospores were artificially inoculated on leaves, and were exposed to full or filtered solar radiation, their survival and germination increased when UV-B wavelengths were removed; significant differences were found 62 h after inoculation. However, UV-B did not affect the extension of germ tubes. This study indicates that the UV-B component of solar radiation plays an important role in the natural regulation of blister blight disease in the field.
