“…For molecular identification, PCR was used to amplify the Internal Transcribed Spacer (ITS) rDNA region (White, Bruns, Lee, & Taylor, 1990). The PCR and fragment purification and sequencing were performed according to Canel, Wagner, Stenglein, and Ludemann (2013). Similarities of the fragment with previously published sequence data were examined with BLASTn (Altschul, Gish, Miller, Myers, & Lipman, 1990) in GenBank (NCBI, http://www.ncbi.nlm.nih.gov/BLAST/).…”

We demonstrate the effectiveness of three inoculation methods (foliar spray, seed immersion and root immersion) in establishing fungal the entomopathogen Beauveria bassiana as an endophyte in tobacco, corn, wheat and soybean. Colonisation of leaves by B. bassiana was assessed 7, 14, 21 and 28 days postinoculation. There were significant differences (p < 0.001) in endophytic colonisation among the different inoculation techniques.

“…Section Circumdati, such as A. westerdijkiae, A. steynii, or A. ochraceus, can produce ochratoxins, which are nephrotoxic and carcinogenic (International Agency for Research on Cancer [IARC], 1993;Hussein and Brasel, 2001;Frisvad et al, 2004). Although these fungi have been of concern as a foodborne pathogen (Duarte et al, 2010;Canel et al, 2013), they are rarely a cause for concern as an airborne pathogen. The qualitative and quantitative frequencies of Aspergillus ochraceus were previously found to be 5.0% and 0.9% in water-damaged buildings in Denmark (Andersen et al, 2011).…”

The results suggest that residents' health could be at risk owing to the high levels of airborne fungi and toxic fungi Aspergillus section Circumdati. Therefore, monitoring and decontamination/disinfection of fungi are strongly recommended before residents are allowed to return permanently to their homes. In addition, returning to home with a certain frequency and adequate ventilation are necessary during similar situations, e.g., when residents cannot stay in their homes for a long period, because fungal levels in houses in the Fukushima Daiichi Nuclear Power Plant evacuation zone were inversely correlated with the frequency with which residents returned to visit their houses.

“…In the present study, A. westerdijkiae was detected in one 20-month ripened pork leg sample. Other types of cured meat products seem to be more affected by this fungus, as Iacumin et al (2011) and Canel et al (2013) reported that up to 34% and 93%, respectively, of Italian sausage casings were contaminated with A. ochraceus/ A. westerdijkiae. More recently, Merla et al (2018) also reported the identification of three A. westerdijkiae isolates in Italian traditional salami samples.…”

Mycobiota and mycotoxins in Portuguese pork, goat and sheep dry-cured hams

The objectives of the present work were to survey, for the first time, the contamination of Portuguese fresh and dry-cured meat products with ochratoxin A (OTA) and aflatoxin B 1 (AFB 1), and to determine the fungi potentially responsible for this contamination. A total of 128 samples including pork fresh legs, dry-cured legs and shoulders, as well as goat and sheep dry-cured legs were analysed. Mycological analysis of these samples yielded a total of 630 fungal isolates. Penicillium sp. was the dominant fungal genus in all products (66% of all isolates). Penicillium nordicum and Aspergillus westerdijkiae were only rarely isolated from pork ham samples. In fresh pork meat, 40% of the samples were contaminated with OTA at levels below 1 μg/kg. In pork dry-cured legs with 20 to 25 months of ripening, 43% of the samples showed detectable contamination, while 18% of the shoulder hams were contaminated. OTA was not detected in any of the goat and sheep samples. OTA contamination does not seem to be a risk in small-piece and short-ripe products like goat and sheep legs, but affects longer ripe products like pork legs and shoulders. Although aflatoxigenic fungi were identified, AFB 1 was not detected in any sample, and it should not be considered a risk in dry-cured hams.
