Nucleic Acids Encoding Norwalk-Like Viruses (NLVs), Their Sequences, and Uses Thereof

Reverse transcription-polymerase chain reaction (RT-PCR) has been used worldwide for the diagnosis of Norwalk-like virus (NLV) infection, yet a commonly accepted genetic classification scheme has not been established. On the basis of the analysis of amino acid sequences in the second open reading frame (ORF2) regions from a total of 101 NLV strains, including 2 bovine strains, a genetic classification scheme is proposed that differentiates 99 human strains into 2 major genetic groups, consisting of 5 and 10 genetic clusters, respectively. The 2 bovine strains constitute a newly defined third major genetic group composed of two putative clusters represented by each strain. This classification scheme is well supported by the analysis of the entire ORF2 sequences from 38 strains selected to represent the genetic diversity of the human strains used above. This scheme should provide a firm scientific basis for designation and evaluation of improved molecular methods for the diagnosis of NLV infection.

Identification of a 54kDa Antigen of Mycoplasma pneumoniae, as Well as Specific Antibodies to This Antigen, in Urine of Infected Individuals

M. pneumoniae is a common cause of atypical pneumonia, tracheobronchitis, and pharyngitis. M. pneumoniae is difficult to culture for diagnostic purposes and serum antibodies used for diagnostic confirmation often arise too late for timely treatment decisions. A specific M. pneumoniae antigen has Start Printed Page 48998been identified which is present during acute infection. This antigen may be used as a diagnostic marker and may also be used to monitor treatment efficacy.

Serotype-Specific Identification of Enterovirus 71 by RT-PCR

Enterovirus 71 (EV71) has been responsible for many outbreaks throughout the world since the early 1970s. Infections can result in severe neurologic symptoms including poliomyelitis-like paralysis. Recently, EV71 caused large outbreaks of hand-foot-mouth disease in Asia with thousands of reported cases. This invention provides a method for the rapid serotype identification of EV71. There are over 780 serotypes of Enteroviruses and many of them have potential for causing diseases with similar symptoms, so viral identification is necessary. Many diagnostic labs would like to implement simple and fast tests to identify viruses. The primer pairs described by these researchers are specific for the Enterovirus agent EV71. The virus is known to be fairly prevalent and the sequencing studies indicate that there are two genetically different groups of this virus. The amplicons produced with these primers allow sequencing and even resolution to which genetic group the virus belongs.

CD40 Ligand Adjuvant for Respiratory Syncytial Virus

CD40 Ligand (CD40L) is an important costimulatory molecule on the T-cell and is central to the development of immunity. CD40L expression can influence cytokine response and is responsible for immunoglobulin class switching in B-cells. CD40L can be used as an adjuvant to enhance cytokine and antibody response to RSV. CD40L can be used as an adjuvant to enhance any immune response, particularly to weak antigens. Expression of CD40L with antigens may enhance the potency or efficacy of vaccines, by enhancing both the antibody response and the T-cell response in terms of cytokine production.

A Novel Method for the Isolation of Helicobacter pylori From Highly Contaminated Specimens

H. pylori is an established cause of chronic gastritis, duodenal and gastric ulcer, and is linked to gastric cancer. H. pylori is difficult to culture from extra-gastric and environmental samples due to heavy contamination with other microorganisms that inhibit the growth of H. pylori on commercially available media. New sample treatment methods which eliminate all other microorganisms while not affecting H. pylori allow diagnostic and environmental samples to be grown on non-selective growth media.

Mosquito Midgut Antigen-based Monoclonal Antibodies That Inhibit the Transmission of Different Species of Human Malaria in Different Mosquito Vectors

Current malaria vaccine development efforts focus primarily on moderating infection in the human host rather than targeting the mosquito vectors responsible for the spread of malaria. A set of monoclonal antibodies has been developed which inhibit the development of human malaria parasites in different species of mosquitos by blocking specific mosquito antigens. It may be possible to develop a malaria transmission blocking vaccine by immunizing humans with DNA or protein forms of the identified mosquito antigens. The human antibodies elicited against such antigens, when ingested by the mosquito along with infectious parasites, may prevent the development of parasites in the mosquito and thus halt malaria transmission.

In Vitro Granuloma as a Model To Examine Tuberculosis Latency

Tuberculin skin testing for M. tuberculosis cannot distinguish between active or latent M. tuberculosis infections; nontuberculosis mycobacteria infections; and BCG Start Printed Page 48999vaccine exposure. Nor can skin testing positively identify M. tuberculosis infections in some immunosuppressed individuals. It is suspected that asymptomatic individuals may harbor latent M. tuberculosis bacilli within lung or lymph node granulomas. An in vitro granuloma model has been developed and four suspected latency genes have been identified. These gene products may be useful for differentiating between latent and active M. tuberculosis infections and for efficacy testing of drug regimens against latent infections.

Isolation and Characterization of Nucleic Acids of the Bartonella henselae virB Operon and Polypeptides Encoded by the virB Operon Nucleic Acids

We have sequenced the VirB virulence operon of B. henselae. This operon consists of 10 genes that could possibly play a role in the pathogensis of Bartonella infections. These genes would therefore be valuable as candidates for diagnostic tools and vaccines. One of the genes within this operon (virB4) encodes a protein of molecular weight 89.5 kDa. This size closely resembles the size (83 kDa) of an immunodominant antigen of B. henselae that has been shown to be reactive with sera from patients diagnosed with cat scratch disease. If these antigens represent the same protein, the 89.5 kDa (virB4) protein could be a viable candidate for developing a diagnostic tool because of the fact that it is a highly conserved, immunodominant antigen. In addition, the lack of cross reactivity of the 83 kDa antigen with other Bartonella species suggests that it would be useful as a candidate antigen for a species-specific diagnostic test to differentiate Bartonella species.

Chimeric Dengue Viruses as Candidate Vaccines for Humans

This invention takes advantage of the attenuating mutations found in the nonstructural regions of a Dengue 2 virus (strain PDK-53). The inventors have created a Dengue 1/Dengue 2 chimera with the nonstructural genes of the avirulant DEN-2 vaccine strain and the structural genes of DEN-1 (strain16007). This recombination provides an attenuated vaccine-type virus which retains the immunogenic properties of DEN-1. New developments for this invention also include a chimeric DEN-2/DEN-3 and DEN-2/DEN-4 virus. These chimeric DEN-2/DEN-1, DEN-2/DEN-3, and DEN-2/DEN-4 viruses are possible components for a tetravalent vaccine to protect humans from all four serotypes of DEN virus.

Gene Coding for a Putative Insecticidal Protein From the Human Pathogen Burkholderia pseudomallei

Burkholderia pseudomallei (previously called Pseudomonas pseudomallei) is a human bacterial pathogen which causes meliodosis, a disease which is endemic in southeast Asia. This discovery of a putative insecticidal protein expressed by B. pseudomallei may have dual functions. A primary application would allow for the development of serological tests for human infection using antibodies derived from the protein and PCR based detection methods derived from the gene sequence. A second possible application of this new protein could include the exploitation of its potential insecticidal properties. These applications might be similar to the methods used to produce a variety of transgenic crops incorporating the Bacillus thuriengensis toxin gene which has been used to create crops resistant to a variety of insect pests.

Rapid Identification of Nocardia farcinica by a PCR Assay Targeting a 409-bp Species-specific DNA Fragment

The bacterial complex Nocardia asteroides is a serious threat to immunosuppressed individuals, especially those with organ transplants, lung disease, and AIDS. Nocardia farcinica is the most clinically significant species because it characteristically demonstrates resistance to multiple, extended spectrum antimicrobial agents. Traditional identification methods are time consuming and labor-intensive (up to 8 weeks for definitive results). This invention comprises a unique DNA sequence within the N. farcinica genome which allows for PCR-based diagnostics which are specific to the species and do not cross react with closely related species and genera.
