Cryptosporidium spp. were detected in 25 of 56 pig slurry samples from 33 Irish farms by PCR and DNA sequencing. The organisms detected included C. suis, Cryptosporidium pig genotype II, and C. muris. We concluded that Cryptosporidium oocysts can persist in treated slurry and potentially contaminate surface water through improper discharge or uncontrolled(More)
Antibiotic resistance, particularly with the fluoroquinolones and macrolide antibiotics, has now emerged globally with thermophilic campylobacters, including Campylobacter jejuni and C. coli, giving rise to concerns about how these organisms have acquired such resistance characteristics, as well as consequences for human and animal treatment. This review(More)
A small study was undertaken to examine the microbiological characteristics of spent mushroom compost (SMC), which is the major waste by-product of the mushroom industry and which is regularly disposed off by application to agricultural land. The primary aim of this study was to examine SMC for the presence of faecal bacterial pathogens, including(More)
Spent mushroom compost (SMC) is a major waste of the mushroom industry with low economic value. SMC arises after mushroom production in phase II compost (pIIC), predominantly comprising straw and chicken litter as principal raw ingredients. The majority of SMC waste is disposed off by application to agricultural land. It is an attractive proposition for(More)
AIMS To examine the prevalence and diversity of bacterial faecal pathogens in unseparated slurry, separated solids and liquid fractions from a commercial pig farm. METHODS A total of 43 stored slurry specimens originating from a fattening house over the period February-April 2002 were analysed, consisting of unseparated (n = 14) slurry, separated solids(More)
Sir, Thermophilic campylobacters, particularly Campylobacter jejuni, Campylobacter coli and Campylobacter lari, continue to remain the most common cause of acute bacterial enteritis in Northern Ireland, with ,743 laboratory reports per annum (equating to circa 44 cases per 100 000 population) and where the trend has been decreasing since 2000 (Figure 1).(More)
In Ireland, conversion of biodegradable farm wastes such as pig manure spent mushroom compost and poultry litter wastes to pelletised fertilisers is a desirable option for farmers. In this paper, results obtained from the composting of pig waste solids (20% w/w) blended with other locally available biodegradable wastes comprising poultry litter (26% w/w),(More)
Polymerase chain reaction amplification of the universal 16S ribosomal RNA (rRNA) gene was performed on a collection of 38 bacterial isolates, originating from air sampled immediately adjacent to the agricultural spreading of bovine slurry. A total of 16 bacterial genera were identified including both Gram-positive and Gram-negative genera. Gram-positive(More)
Globally, Cryptosporidium infection continues to be a significant health problem where it is recognized as an important cause of diarrhoea in both immunocompromised and immunocompetent people. In developing countries persistent diarrhoea is the leading cause of death in children younger than five years of age, where it accounts for 30 to 50 percent of those(More)
Mushroom worker's lung (MWL) is a hypersensitivity pneumonitis or allergic alveolitis caused by a type III IgG-mediated immunopathogenic inflammatory reaction in the host due to the inhalation of several thermophilic organisms, including Thermoactinomyces spp. It is difficult to distinguish phenotypically the eight species of this genus; therefore, this(More)
