Nicolaisen, M, Supronienė S, Nielsen LK, Lazzaro I; S, Henrik N, Justesen AF.  2009.  Real-time PCR for quantification of eleven individual Fusarium species in cereals. Abstract

Contamination of cereals with Fusarium species is one of the major sources of mycotoxins in food and feed. Quantification of biomass of Fusarium species is essential to understand the interactions of individual species in disease development. In this study quantitative real-time PCR assays based on the elongation factor 1 α (EF1α) gene for the 11 Fusarium species F. graminearum, F. culmorum, F. poae, F. langsethiae, F. sporotrichioides, F. equiseti, F. tricinctum, F. avenaceum, F. verticillioides, F. subglutinans and F. proliferatum were developed and tested on 24 wheat and 24 maize field samples. The assays were found to be specific and sensitive. Generally, the results from the quantitative real-time PCR assays corresponded well with mycotoxin data of the field samples

Nielsen, L, Sang-oum W, Cheevadhanarak S, Flegel TW.  2005.  Taura syndrome virus (TSV) in Thailand and its relationship to TSV in China and the Americas. Abstract

The cultivation of exotic Penaeus vannamei in Thailand began on a very limited scale in the late 1990s, but a Thai government ban on the cultivation of P. monodon in freshwater areas in 2000 led many Thai shrimp farmers to shift to cultivation of P. vannamei. Alarmed by the possibility of Taura syndrome virus (TSV) introduction, the Thai Department of Fisheries required that imported stocks of P. vannamei be certified free of TSV by RT-PCR (Reverse Trasciption Polymerase Chain Reaction) testing. During the interval of allowed importation, over 150 000 broodstock shrimp were imported, 67% of these from China and Taiwan. Despite the safeguards, TSV outbreaks occurred and we confirmed the first outbreak by RT-PCR in early 2003. This resulted in a governmental ban on all shrimp broodstock imports from February 2003, but TSV outbreaks have continued, possibly due to original introductions or to the continued illegal importation of stocks. To determine the origin of the TSV in Thailand, the viral coat protein gene VP1 was amplified by RT-PCR from several shrimp specimens found positive for TSV by RT-PCR from January to November 2003. These included 7 samples from P. vannamei disease outbreaks in Thailand, 3 other non-diseased shrimp samples from Thailand and Burma and 6 samples including P. vannamei and P. japonicus from China. Comparison revealed that the Thai, Burmese and Chinese TSV types formed a clade distinct from a clade of TSV types from the Americas.

Flegel, TW, Nielsen L, Thamavit V, Kongtim S, Pasharawipas T.  2004.  Presence of multiple viruses in non-diseased, cultivated shrimp at harvest. Abstract

Histological examinations were carried out with 400 cultivated black tiger shrimp (Penaeus monodon) from 12 commercial rearing ponds from three different areas in Thailand over a period of 3 years. The shrimp were collected at or near harvest time as two arbitrary size groups of 10–20 each from each pond. Aside from size difference, they showed no gross signs of disease and were normally active. Pathognomonic histopathological lesions were found only for hepatopancreatic parvovirus (HPV) or monodon baculovirus (MBV). Although these were relatively frequent, no unusual shrimp mortality had occurred in any of the ponds examined. Severity of these infections was negatively correlated with shrimp size. When grouped together, HPV-infected shrimp gave mean lengths of approximately 6.5 cm that were significantly different from uninfected shrimp at 9 cm length, early in the cultivation cycle while MBV-infected groups of approximately 9 cm length were not readily distinguishable until uninfected shrimp were 10 cm or more, later in cultivation. Thus, HPV infection was correlated with more severe stunting than MBV. In addition to histopathological examination, polymerase chain reaction (PCR) assays for HPV, white spot syndrome virus (WSSV) and infectious hypodermal and hematopoietic necrosis virus (IHHNV) were carried out on one large sample of 240 shrimp from 6 ponds where visible lesions were apparent for MBV only. Surprisingly, 94% of the specimens gave a positive test for at least one of the four viruses. HPV and IHHNV alone or in combination were detected at high prevalence (approximately 60%) despite the absence of visible histological lesions and were confirmed by southern blot hybridization. Although the prevalence of the four viral pathogens was very high, it would normally have gone unnoticed, since normal shrimp are rarely examined for viruses.

Nielsen, L.  1999.  Stepmothers: Why so much stress? A review of the research Abstract

Recent psychological and sociological literature is reviewed in answering two questions: What factors generally affect how much stress women encounter as stepmothers? Why do stepmothers often experience more stress than stepfathers? The answers seem to lie in four areas: (1) our society's attitudes about mothers and motherhood; (2) the mother's and stepmother's personalities, attitudes, and circumstances; (3) the father's attitudes and his relationship with the mother; and (4) the stepchildren's gender and mental health.
