Two horses were diagnosed as having Mycobacterium ulcerans infections. The first was a 21-year-old Quarterhorse-cross mare living in Mallacoota (a coastal town near the border of New South Wales and Victoria, Australia) that presented with lichenification, hair-loss and oedema on a fetlock, which subsequently ulcerated, as well as a non-healing ulcer on the wither. The second horse was a 32 year-old Standardbred gelding from Nicholson, near Bairnsdale, Victoria, that had an ulcerated lesion on its caudal thigh. Histologically, there were characteristic changes seen with M. ulcerans infections in other species, including extensive necrosis without associated granulomatous inflammation. The organisms were seen in Ziehl-Neelsen-stained smears or sections of the lesions from both horses and were isolated in culture from the first horse. A definitive diagnosis was provided by real-time polymerase chain reaction targeting the M. ulcerans-specific insertion sequence, IS2404. Delayed identification of the infectious agent in the first case led to the use of suboptimal antimicrobial therapy, resulting in failure to control the infection and the horse was subsequently euthanased. The second horse was successfully treated following surgical debulking of the centre of the lesion and one session of aggressive cryosurgery. Mycobacterium ulcerans should be considered in the differential diagnosis of unexplained lichenification with oedematous and ulcerated skin lesions in horses living in regions where this organism is endemic. 相似文献

Isolation of 2,6-dibromophenol from the marine hemichordate, Balanoglossus biminiensis 总被引:1,自引:0,他引:1
2,6-Dibromophenol has been isolated from a luminous marine enteropneust, Balanoglossus biminiensis, found on intertidal beach areas at Sapelo Island, Georgia. This compound, responsible for the characteristic "iodoform-like" odor of these animals, is present in relatively large amounts; the estimated quantity per organism is 10 to 15 milligrams. Identity of the isolated substance as 2,6 dibromophenol is based on analyses of ultraviolet, infrared, and nuclear magnetic resonance spectra, mass spectrometry analysis, and on melting-point data. 相似文献

A review of the smallholder dairy production in Malawi was conducted using livestock annual reports and other literature that
was supplemented with primary data from a baseline survey conducted in December 2009. Smallholder dairy farming in Malawi
operates with support from institutions that facilitate access to initial stock and dairy production technologies. Most farmers
(94%) keep the animals in pens where feed is provided throughout the year. Results indicated unsatisfactory feeding, housing
and health management practices, which negatively impact cow fertility. Dairy population trends suggest low replacement rates,
which could be associated to low cow fertility and inadequate management skills. There are challenges related to access to
breeding and health services, which further contribute to low productivity. Low fertility is evidenced by low calving rates
(22–61%) and long calving interval (405–549 days). Existence of programmes on farmer capacity building provides an opportunity
for improved management skills and cow productivity. It is concluded that dairy cow management and fertility have challenges
and opportunities that are influenced by the extent to which farmers have access to important services such as extension,
health, breeding and finance. 相似文献

SUMMARY This report summarises the range of Salmonella serovars and phage types found in humans in Australia during the years 1987 to 1992 inclusive, and compares them with serovars from food animals and raw meats for the same period. It also compares the major serovars found from different animal sources with their frequency from humans. The common serovars from animal feeds are compared with their frequency from animals. 相似文献

The effects of translucent polyethylene sheeting as a thermal covering to eradicate Pueraria montana (kudzu) were investigated at Clemson, South Carolina on a clay loam. In 2005, the highest reduction of live root crowns was observed where P. montana was covered for the entire growing season (May–October) with a reduction of 42% of live root crowns compared with the control plots. Where P. montana was covered for alternate weeks throughout the growing season live root crowns were reduced by 35%. Covering P. montana for one week and then uncovering for four weeks repeatedly through the season killed 24% of root crowns. In 2006, the second year of treatment to the same plots, the three solarization treatments had similar efficacy of about 97%. The use of polyethylene sheeting appears not to be cost‐effective for general control of large P. montana infestations, but may be useful for small patches. 相似文献
