The LIMS has not only reduced the workload on laboratory staff but also minimized downtime, enhancing overall productivity and operational continuity. Fieldale Farms, a family-owned business founded over 50 years ago in Northeast Georgia, has grown into one of the world’s largest independent poultry producers. Despite its growth, the company remains rooted within a 60-mile radius of its ...
To achieve this goal, we have analyzed anonymized data on the immune status of self-referral volunteers that have been determined at local pharmacies through a low-entry-barrier point-of-care analysis approach. The seroprevalence values for immunoglobulin type G antibodies against SARS-CoV-2 antigens obtained by rapid diagnostic testing on peripheral blood from volunteers reflect ...
(A) Thymic stromal lymphopoietin (TSLP), (B) thymus and activation regulated chemokine (TARC) and (C) macrophage-derived chemokine (MDC) were analyzed through real-time PCR. Statistical analyses were performed using the Mann–Whitney U-test for comparison with DFE+PBS mice (N= 7–9 mice per group). ...
Although Vietnamese residents frequently harbor extended-spectrum β-lactamase-producing Escherichia coli (ESBL-E), it is unclear which foods/beverages are risk factors for acquiring these bacteria. The aim of this study was to evaluate the frequency with which edible ice served in restaurants is contaminated with antibiotic-resistant bacteria, and thereby clarify whether this product poses a ...
Seventy-three schools were included in the study and tap water samples were analyzed by conventional PCR for the presence of HAdV, hEV, and GARV genomes. hEV showed the highest detection rate (27.4%), followed by HAdV (23.3%), and GARV (16.4%). ...
Forty-nine water samples from a public building were analyzed by a culture method (BCYE agar) and a specific semi-nested polymerase chain reaction (PCR). ...
The sensitivity of this method was subsequently determined using purified E. histolytica genomic DNA and culture cells as PCR reaction templates. Results indicated that conventional PCR visualized on 1% agarose gel was able to detect as low as 0.02 pg genomic DNA and 5 cells, while real-time PCR could detect 0.01 pg genomic DNA and 2 cells of E. ...
Multiple microbial source tracking methods were applied to investigate spatial variation in faecal pollution sources impacting a 1.7 km freshwater beach on Lake Ontario (Canada). The highest E. coli concentrations measured in the study area were from interstitial sand pore water at Sunnyside Beach, reaching 2.6 × 106 CFU/100 ml. These E. coli concentrations exceeded those in the nearby Humber ...
Tetracycline-resistant bacteria and genes encoding tetracycline resistance are common in anthropogenic environments. We studied how wastewater treatment affects the prevalence and concentration of two genes, tetA and tetB, that encode resistance to tetracycline. Using real-time polymerase chain reaction (PCR) we analysed wastewater samples collected monthly for one year at eight key-sites in a ...
The consumption of lactate and amino acids is very important for microbial development and/or aroma production during cheese ripening. A strain of Yarrowia lipolytica isolated from cheese was grown in a liquid medium containing lactate in the presence of a low (0.1x) or high (2x) concentration of amino acids. Our results show that there was a dramatic increase in the growth of Y. ...
The sigB gene of Corynebacterium glutamicum encodes a group 2 sigma factor of RNA polymerase. Under conditions of oxygen deprivation, the sigB gene is upregulated and cells exhibit high productivity of organic acids as a result of an elevated glucose consumption rate. Using DNA microarray and quantitative reverse transcription-PCR (RT-PCR) analyses, we found that sigB disruption led to reduced ...
To develop an efficient screening method for detection of the transgene in Chinese cabbage (Brassica rapa spp. pekinensis) utilizing Basta spray, optimal conditions for Basta application were examined in this study. Two transgenic Chinese cabbage lines were obtained through Agrobacterium-mediated transformation and used as transgenic positive controls in the Basta screening experiment. ...
A total of 26 strains of Vibrio cholerae, including members of the O1, O139, and non-O1, non-O139 serogroups from both clinical and environmental sources, were examined for the presence of genes encoding cholera toxin (ctxA), zonula occludens toxin (zot), accessory cholera enterotoxin (ace), hemolysin (hlyA), NAG-specific heat-stable toxin (st), toxin-coregulated pilus (tcpA), and outer membrane ...
