[PMID: 38921227 DOI: 10.3390/biomimetics9060347] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 05/28/2024] [Accepted: 06/05/2024] [Indexed: 06/27/2024] Open
Abstract
In the biomedical fields of bone regenerative therapy, the immobilization of proteins on the bioceramic particles to maintain their highly ordered structures is significantly important. In this review, we comprehensively discussed the importance of the specific surface layer, which can be called "non-apatitic layer", affecting the immobilization of proteins on particles such as hydroxyapatite and amorphous silica. It was suggested that the water molecules and ions contained in the non-apatitic layer can determine and control the protein immobilization states. In amorphous silica particles, the direct interactions between proteins and silanol groups make it difficult to immobilize the proteins and maintain their highly ordered structures. Thus, the importance of the formation of a surface layer consisting of water molecules and ions (i.e., a non-apatitic layer) on the particle surfaces for immobilizing proteins and maintaining their highly ordered structures was suggested and described. In particular, chlorine-containing amorphous silica particles were also described, which can effectively form the surface layer of protein immobilization carriers. The design of the bio-interactive and bio-compatible surfaces for protein immobilization while maintaining the highly ordered structures will improve cell adhesion and tissue formation, thereby contributing to the construction of social infrastructures to support super-aged society.

Abstract
Norovirus (NoV) is known to be the second nonbacterial enteric pathogen after rotavirus that causes acute gastroenteritis. They can be spread from person to person through fecal-oral routes. Infection can lead to severe diarrhea, causing stomach pain, vomiting, and nausea. Rapid detection of NoV can control huge economic and productive losses. Genotyping various emerging NoV strains is important to compare the severity among different strains. Conventional immunological and molecular methods have evolved and contributed to developing detection techniques. Immunological (enzyme-linked immunosorbent assay) and molecular detection (reverse transcriptase polymerase chain reaction [RT-PCR], RT-quantitative PCR, loop-mediated isothermal amplification, nucleic acid sequence-based alignment, recombinase polymerase amplification) methods have been mainly used. The development of biosensors using aptasensor, affinity peptides, nanoparticles, microfluidics, and so on, are currently the most researched topics. The availability of next-generation sequencing technologies has greatly influenced the diagnosis of NoV. The complementation of advanced technologies is helpful in identification of new variants. In this study, techniques that are useful in detecting NoV are discussed. This review has investigated the availability of recent methods used in the detection, present status, and futuristic plan of action in case of outbreak and pandemic.

Abstract
Human norovirus (HuNoV) is a food-borne pathogen that causes acute gastroenteritis in people of all ages worldwide. However, no approved vaccines and antiviral drugs are available at present. Therefore, the development of accurate and rapid detection technologies is important in controlling the outbreak of HuNoVs. This paper reviewed the research progress on HuNoV detection, including immunological methods, molecular detection and biosensor technology. Immunological methods and molecular detection technologies are still widely used for HuNoV detection. Furthermore, biosensors will become an emerging developmental direction for the rapid detection of HuNoVs because of their high sensitivity, low cost, easy operation and suitability for onsite detection.

Abstract
Noroviruses are the leading cause of acute gastroenteritis in all age groups and constitute a major health and economic burden worldwide. This systematic review and meta-analysis aimed to determine the diagnostic accuracy of immunochromatographic tests (ICTs) for the detection of norovirus in stool specimens, which has not been performed previously. In this systematic review and meta-analysis (registered on PROSPERO, CRD42020186911), we searched Medline/PubMed, Embase, Cochrane Library, and Web of Science for all studies published up to 16 May 2020. The values for sensitivity, specificity, positive likelihood ratio (LR+), negative likelihood ratio (LR-), and diagnostic odds ratio (DOR) of ICTs with 95% confidence interval (CI) were pooled using a bivariate random-effects model. The summary receiver operating characteristic curve and area under the curve were used to summarize overall test accuracy. We included 43 studies describing 7,428 samples. The overall estimates of sensitivity, specificity, LR+, LR-, DOR, and accuracy of ICT for diagnosing norovirus were 0.61 (95% CI, 0.54 to 0.67), 0.97 (95% CI, 0.95 to 0.98), 17.08 (95% CI, 11.15 to 26.18), 0.40 (95% CI, 0.34 to 0.46), 53.9 (95% CI, 31.32 to 92.78), and 0.928, respectively. Significant differences in pooled sensitivities were noted between age groups and in pooled DOR and LR+ between genogroups of included samples. ICT provides low sensitivity but high specificity and accuracy for detecting norovirus. Thus, an ICT for norovirus can be a rapid and convenient way for identifying patients early; however, a negative result cannot rule out norovirus infection and should be confirmed by a reference test.

Determining effectiveness of rotavirus vaccine by immunochromatography and reverse transcriptase polymerase chain reaction: A comparison. Vaccine 2019; 37:5886-5890.

Abstract
INTRODUCTION Because of the large animal reservoirs and reassortment capacity of rotaviruses (RVs) that pose the possibilities of waning the effectiveness of RV-vaccines, it remains essential to monitor vaccine effectiveness (VE) regularly. Although reverse transcription polymerase chain reaction (RT-PCR) remains sensitive for RV detection, physicians, especially in Japan, frequently use immunochromatography (IC)-based kits for RV diagnosis. Recently, IC is being used to calculate VE also. Herein, we investigated the validity of VEs determined by IC compared to that by RT-PCR during an outbreak in Shizuoka Prefecture, Japan. METHODS RVs in the stool or rectal swabs from children with acute gastroenteritis (AGE) were tested first by IC in the clinic and then by RT-PCR in the laboratory. A test-negative study design was used to examine VE. RESULTS Although the specificity of IC assay revealed 100%, its sensitivity remained weaker (67%) than that of RT-PCR that increased up to 88% depending on disease severity. VE assessed by IC remained stronger than that by RT-PCR: 79% (95% CI: 39-93%) by IC, and 58% (95% CI: -20% to 90%) by RT-PCR. However, VEs by IC and RT-PCR appeared almost similar in higher disease severity: 81.5% (95% CI: 40-94%) by IC and 72% (95% CI: 7-92%) by RT-PCR at severity ≥7, while 97.5% (95% CI: 77-99.7%) by IC and 92% (95% CI: 58-98%) by RT-PCR at severity ≥11. We showed that RV-vaccinated children had 80% [OR = 0.192 (95% CI: 0.052-0.709) less chance to be detected by IC. CONCLUSION Although the sensitivity and specificity of IC differ by brand type, generally, IC is not as sensitive as RT-PCR. Despite the VEs remain higher by IC, it looks comparable with that of RT-PCR in severe cases implying that VEs evaluated by IC against severe illness remain useful for VE-monitoring.

Abstract
Worldwide, norovirus is one of the most associated causes of acute gastroenteritis, which leads to nearly 50 000 child deaths every year in developing countries. Therefore, there is great demand to develop a rapid, low-cost, and accurate detection assay for the foodborne norovirus infection to reduce mortality caused by norovirus. Considering the importance of norovirus, we have demonstrated a highly sensitive and specific colorimetric detection method for analysis of human norovirus genogroups I and II (HuNoV GI and GII) in oyster samples. This is the first report to employ colorimetric HRPzyme-integrated polymerase chain reaction (PCR) for direct norovirus detection from the real shellfish samples. We found that the HRPzyme-integrated PCR method is more sensitive than the gel electrophoresis approach and could detect the HuNoV GI and GII genome up to 1 copy/mL. The specificity of the proposed method was successfully demonstrated for HuNoV GI and GII. Further, we performed testing HuNoVs in the spiked oyster samples, and the HRPzyme-integrated PCR method proved to be an ultrasensitive and selective method for detecting HuNoVs in the real samples. By integration of the proposed method with the portable PCR machine, it would be more reliable to improve food safety by detecting HuNoVs in the different types of shellfish, such as oyster and mussel, at the production field.

Abstract
An external force-assisted near-field illumination biosensor (EFA-NI biosensor) detects a target substance that is propelled through an evanescent field by an external force. The target substance is sandwiched between an antibody coupled to a magnetic bead and an antibody coupled to a polystyrene bead. The external force is supplied by a magnetic field. The magnetic bead propels the target substance and the polystyrene bead emits an optical signal. The detection protocol includes only two steps; mixing the sample solution with a detection reagent containing the antibody-coated beads and injecting the sample mixture into a liquid cell. Because the system detects the motion of the beads, the sensor allows detection of trace amounts of target substances without a washing step. The detection capability of the sensor was demonstrated by the detection of norovirus virus-like particles at a concentration of ~40 particles per 100 μl in contaminated water.

Abstract
Norovirus is an important cause of gastroenteritis outbreaks globally and the most prevalent cause of sporadic gastroenteritis in many regions. Rapid and accurate identification of causative viral agents is critical for outbreak investigation, disease surveillance, and management. Because norovirus is not cultivable and has a highly diversified and variable genome, it is difficult to develop diagnostic assays. Detection methods have evolved from electron microscopy to conventional end-point reverse transcription polymerase chain reaction (RT-PCR), immunoassay, real-time RT-PCR, other molecular technologies, and nanotechnology array-based assays. The status and features of various testing methods are summarized in this review.

Abstract
Human norovirus is a major cause of both sporadic cases and outbreaks of gastroenteritis and comprises two main genogroups (GI and GII) which, in turn, comprise a variety of genotypes. The current study examined the efficacy of the Bioline SD kit using fecal material from Australian gastroenteritis incidents. At best, the SD kit had a sensitivity of 62%. Freezing and thawing specimens before testing significantly improved sensitivity. The SD kit had a specificity of 98.6%. Genotype analysis (Open Reading Frame 2) indicated the SD kit could detect a range of genotypes and genotype variants including GI.1, GI.3, GI.4, GII.1, GII.3, GII.4 (unclassified), GII.4 (2006b), GII.4 (2009), GII.4 (2012) and GII.6 but the kit failed to detect GI.2 and GII.2 norovirus. The kit did not cross-react with a number of common fecal viruses including astrovirus, sapovirus, rotavirus or adenovirus. The kit was very easy to use and would be valuable in point-of-care testing.

Abstract
Noroviruses (NoVs) are a major cause of gastroenteritis worldwide in humans and animals and are known as very infectious viral agents. They are spread through feces and vomit via several transmission routes involving person-to-person contact, food, and water. Investigation of these transmission routes requires sensitive methods for detection of NoVs. As NoVs cannot be cultivated to date, detection of these viruses relies on the use of molecular methods such as (real-time) reverse transcriptase polymerase chain reaction (RT-PCR). Regardless of the matrix, detection of NoVs generally requires three subsequent steps: a virus extraction step, RNA purification, and molecular detection of the purified RNA, occasionally followed by molecular genotyping. The current review mainly focused on the molecular detection and genotyping of NoVs. The most conserved region in the genome of human infective NoVs is the ORF1/ORF2 junction and has been used as a preferred target region for molecular detection of NoVs by methods such as (real-time) RT-PCR, NASBA, and LAMP. In case of animal NoVs, broad range molecular assays have most frequently been applied for molecular detection. Regarding genotyping of NoVs, five regions situated in the polymerase and capsid genes have been used for conventional RT-PCR amplification and sequencing. As the expected levels of NoVs on food and in water are very low and inhibition of molecular methods can occur in these matrices, quality control including adequate positive and negative controls is an essential part of NoV detection. Although the development of molecular methods for NoV detection has certainly aided in the understanding of NoV transmission, it has also led to new problems such as the question whether low levels of human NoV detected on fresh produce and shellfish could pose a threat to public health.

Abstract
BACKGROUND The rapid detection of noroviruses is essential to implement measures to reduce the rapid spread of gastroenteritis infections they cause, notably in institutions. OBJECTIVES To evaluate 4 rapid immunochromatographic tests: RIDA(®)QUICK Norovirus, ImmunoCardSTAT!(®) Norovirus, NOROTOP(®) and SD BIOLINE NOROVIRUS by determining their sensitivity and specificity on a large panel of samples representing 11 genotypes of norovirus genogroup I and 14 of genogroup II, and their cross-reactivity with other enteric viruses. STUDY DESIGN Thawed stool samples containing norovirus genogroup I or II or other enteric viruses, and negative samples, were tested by the 4 assays and compared to the reference standard RT-PCR. Fresh stool samples were also tested by RIDA(®)QUICK. RESULTS The sensitivity of RIDA(®)QUICK, ImmunoCardSTAT!(®), NOROTOP(®) and SD BIOLINE for the detection of norovirus genogroup I on thawed samples was 17%, 26%, 52% and 23%, respectively. For genogroup II, the sensitivity was 64%, 39%, 50% and 54%, respectively. For GII.4, the main circulating genotype, the sensitivity was 78%, 59%, 61% and 67%, respectively. For all tests, the specificity was 100% and no cross-reactivity with other enteric viruses was observed. The sensitivity of RIDA(®)QUICK on fresh stool samples positive for GII.4 was 71%. CONCLUSIONS Knowing that most gastroenteritis cases are due to GII.4, the immunochromatographic tests may be useful for preliminary screening, notably in outbreaks. However, negative samples need to be tested using RT-PCR methods.

Abstract
The analytical and clinical performance of a new rapid immunochromatography test, the SD Bioline Norovirus test, was evaluated for the detection of human norovirus in fecal specimens. The analytical performance studies were performed for detection limit, reproducibility, cross-reactivity, and interference. For comparison, 92 norovirus-positive stool samples and 126 norovirus-negative samples for which the results were confirmed by 2 different real-time PCR kits were used. The rapid immunochromatography test detected the equivalent of 4.48×10(6) copies/mL of the norovirus genome in stool samples. On performing the repeatability/reproducibility test, samples above this concentration all provided positive results (100%) and 97.8% of the samples slightly below this concentration (2.45×10(6) copies/mL) provided negative results. No cross-reactivity or interference was detected. Positive percent agreement (sensitivity), negative percent agreement (specificity), and overall percent agreement of the rapid immunochromatography test compared with testing by real-time PCR were 90.2%, 100%, and 95.9%, respectively. In addition, the rapid immunochromatography test was completed within 20 min. The SD Bioline Norovirus test was, therefore, easier and more rapid to perform and showed excellent reproducibility, no cross-reactivity, no interference, and high agreement compared with real-time PCR. Thus, this test is useful for rapid screening to identity norovirus infection.

Abstract
Rapid and accurate detection of norovirus is essential for the prevention and control of norovirus outbreaks. This study compared the effectiveness of a new immunochromatographic assay kit (SD BIOLINE Norovirus; Standard Diagnostics, Korea) and real-time reverse transcription-PCR (RT-PCR) for detecting norovirus in fecal specimens. Compared with real-time RT-PCR, the new assay had sensitivity, specificity, positive predictive value, and negative predictive value of 76.5% (52/68), 99.7% (342/343), 98.1% (52/53), and 95.5% (342/358), respectively. The sensitivity of the assay was 81.8% (18/22) for GII.3 and 75.7% (28/37) for GII.4. None of the 38 enteric virus-positive specimens (3 for astrovirus, 5 for enteric adenovirus, and 30 for rotavirus) tested positive in the cross-reactivity test performed by using this assay. The new immunochromatographic assay may be a useful screening tool for the rapid detection of norovirus in sporadic and outbreak cases; however, negative results may require confirmatory assays of greater sensitivity.

Abstract
Noroviruses (NoVs) are major agents of gastroenteritis outbreaks and hospitalization worldwide. This study evaluated the sensitivity and specificity of the commercially available third-generation RIDASCREEN® Norovirus Enzyme Immunoassay (EIA) kit in comparison to the reverse transcription-polymerase chain reaction (RT-PCR) to detect NoVs in hospitalized children with gastroenteritis. An agreement of 88% (81/92) was observed when comparing EIA with RT-PCR. A sensitivity of 92% and a specificity of 83.3% were demonstrated. Eleven samples were positive by 1 method only (4 RT-PCR/7 EIA). Fourteen samples were sequenced and all classified as NoV genogroup GII-4. The 7 positive only by EIA were also evaluated by electron microscopy, and in 3 (42.9%) samples viral particles with a suggestive morphology of NoVs were visualized. These same samples were tested by seminested-RT-PCR with a positivity of 85.7%. The results obtained in this study demonstrated a significant improvement in the sensitivity and specificity of this updated assay.

Abstract
In this study, the sensitivity and specificity of three immunochromatography (IC) test kits for rapid detection of group A rotavirus were compared and evaluated with stool samples collected from children, who suffered from acute gastroenteritis during February to June, 2009 in Japan. A total of 86 stool samples were tested and compared with a reference RT-PCR method. The sensitivity among IP-Rota V, Dipstick Eiken ROTA and ROTA-ADENO test kits were 97.2, 95.8 and 88.7%, while the specificity were 100, 93.3 and 100%, respectively. It was demonstrated that the IC kits evaluated in this study could be used as an alternative method for the rapid screening of group A rotavirus in fecal specimens, especially during acute gastroenteritis outbreak season.

Abstract
Norovirus (NoV) is a causative agent of gastroenteritis in children and adults worldwide. Although reverse transcription-polymerase chain reaction (RT-PCR) has been accepted as the standard method for diagnosis of NoV infection, it requires well-trained personnel and sophisticated equipments. Performance of a commercial immunochromatography (IC) test for rapid detection of NoV was evaluated with fecal specimens collected from children admitted to a hospital with acute gastroenteritis during 2005-2007 in Chiang Mai, Thailand. A total of 463 fecal specimens were tested for the presence of NoV by a commercial immunochromatography kit (IP-NoV) and by RT-PCR. Sensitivity, specificity, and agreement of immunochromatography as compared to RT-PCR were 74.2%, 99.5%, and 96.1%, respectively. Based on the NoV genotypes determined by phylogenetic analysis, immunochromatography detected NoV GII/3, GII/4, GII/6, GII/13, GII/15, and GII/16 genotypes. The findings indicate that the immunochromatography kit could be used for a direct detection of NoV GII in clinical specimens and covering a wide range of NoV genotypes circulating in Thailand.

Abstract
Norovirus (NoV) is the leading cause of acute gastroenteritis worldwide. Currently, reverse transcription polymerase chain reaction (RT-PCR) is used commonly to detect NoVs in both clinical and environmental samples. However, RT-PCR requires expensive equipment and cannot be performed on site. In this study, a latex agglutination test (LAT) using antibody-labeled latex beads for detecting NoVs was developed. Two kinds of polyclonal antibodies, one generated from synthetic peptides and the other from E. coli-expressed NoV capsid proteins, were used to develop the LAT. Each of these polyclonal antibodies was immobilized on the surface of latex beads and tested for the ability to detect NoVs. Under optimized conditions, our LAT detected GII.4 NoV at concentrations as low as 3.3x10(5) RT-PCR units/ml in stool samples. The detection limit for the LAT was approximately 1.7 103 RT-PCR units. Forty-eight stool samples were tested for NoVs using this LAT. In comparison with an RT-PCR assay, the sensitivity and specificity of the LAT were 35% and 100%, respectively. With further optimization, this LAT used with appropriate antibodies could be applied for convenient detection of NoVs in clinical diagnosis and food monitoring.

Abstract
BACKGROUND The importance of norovirus as a cause of gastroenteritis outbreaks is well documented, but the role of norovirus in sporadic acute severe gastroenteritis is not so well established. The aim of this study was to determine the prevalence and clinical characteristics of norovirus gastroenteritis among hospitalized children. METHODS A prospective study was conducted in children less than 5 years old, admitted with acute gastroenteritis between January 2005 and January 2008 to the Pediatrics Department of the Universitary Hospital, Albacete, Spain. Demographic and clinical data were collected. A stool sample from each child was screened for enteropathogenic bacteria and tested by reverse transcription polymerase chain reaction for rotavirus, astrovirus, norovirus, and sapovirus and by immunochromatographic method for enteric adenoviruses. RESULTS Norovirus was the second most frequent pathogen after rotavirus, being detected in 61 (17.3%) of the 352 children enrolled, in 29 of them (8.2%) as single agent. Mixed infections involving other viruses or bacteria were present in 52.4% of norovirus positive samples, a nosocomial source of infection was demonstrated in 17.2%. Norovirus infection was more prevalent in winter and affected mainly children less than 2 years of age. Vomiting was present in 68% and fever in 48.3% of cases, 3 children had nonfebrile seizures. Compared with rotavirus enteritis, norovirus infection was slightly less severe (in terms of severity score and need of intravenous rehydration) and fever was less frequent. CONCLUSIONS Norovirus was a frequent cause of acute severe sporadic gastroenteritis in children representing the second etiologic agent after rotavirus.

Abstract
An immunochromatography (IC) assay for rapid detection of norovirus (NoV) was evaluated with fecal samples collected from children who suffered from acute gastroenteritis during the winter season of 2007-2008 in Japan. A total of 75 fecal specimens were tested for NoV by the newly developed IC kit and by a gold standard RT-PCR method. The sensitivity, specificity, and agreement of this IC kit were 75.4%, 100%, and 80%, respectively. In addition, phylogenetic analysis revealed that the majority of NoV circulating in Japan during 2007-2008 belonged to the new variant GII/4 2006b genetic cluster. It was demonstrated that the IC kit evaluated in this study could detect these new variant NoV strains, which emerged recently in Japan. Therefore, it is suggested that this NoV IC kit could be used as an alternative method for the screening of NoV in fecal specimens, especially during the season of acute gastroenteritis outbreak.

Abstract
Acute gastroenteritis is one of the most common diseases, affecting children worldwide. Viruses are recognized as a major cause of this disease, particularly in children. Since the Norwalk virus was identified as a cause of gastroenteritis, the number of viral agents associated with diarrheal disease in humans has progressively increased. Rotavirus is the most common cause of severe diarrhea in children under 5 years of age. Human astroviruses, caliciviruses and enteric adenovirus are also important etiologic agents of acute gastroenteritis. Other viruses such as toroviruses, coronaviruses, picobirnaviruses, Aichi virus and human bocavirus are increasingly being identified as causative agents of diarrhea. Vaccination against rotavirus could prevent cases of severe diarrhea and reduce the mortality attributable to this disease.
