The developing multi drug resistant Neisseria gonorrhoeae, the severe symptoms of the gonococcal infections, added to the socioeconomic burden and epidemiologically threatening aspects of the disease; drug resistance gonorrhea, its detection and diagnosis has acquired immense significance (Blomquist, et al., 2014). It is important to focus on preventing the spread of resistant forms as part of disease management. An essential requirement for controlling spread is enhancing surveillance through better diagnostic methods for identification and isolation of disease resistant pathogens. This project aims to introduce a novel method of diagnosis of drug resistance in clinical isolates of gonorrhea.
The method presented in this paper involves the use of Tiling array for diagnosis of drug resistance in clinical isolates of Neisseria gonorrhoeae. The protocol is based on similar technology already used for development of protocols for drug resistance in other organisms.
Tiling array is a derivation of microarray technology developed by Kapranov and colleagues (2002) and Shoemaker and colleagues (2001) that facilitates identification of previously unidentified transcripts through genome wide annotations.
The initial euphoria associated with the utility and significance of antibacterial and antimicrobial drugs seems to fade with the rise in the bacterial strains exhibiting resistance to single as well as multiple drugs. Hence drug resistance has become an exponentially rising global health hazard rendering world population once again vulnerable to the threats of common diseases (Levy & Marshall, 2004). Both Gram positive and Gram negative bacteria have been known to exhibit multi-drug resistance leaving health care providers with no antimicrobial therapeutic agents ensuring control and management of ...Download file to see next pagesRead More

Biochemistry and Molecular Biology

...Biochemistry and Molecular Biology Introduction: The concepts of biochemistry and molecular biology are slightly different yet related to each other. While molecular biology is determined on an understanding of the molecular activities within a living organism, the study of biochemistry focuses on the findings obtained as a result of the molecular biology thus enhancing the knowledge on the different molecular and cellular processes within the living organism (Wilson & Walker, 2010, p.1). The present study has taken into consideration certain molecular...

...of a 1200 bp mouse genomic DNA fragment in E. coli. b) A plasmid for expression of a eukaryotic yeast gene in the prokaryote, E. coli. c) A plasmid to determine if a specific 800 bp region of human genomic DNA has the ability to control transcription (i.e. whether the region is a gene promoter). d) A plasmid to allow manipulation of a DNA fragment in E. coli and to also allow the expression of the fragment in mammalian cells. Question 7 (8%) Define the following in the molecular biology context: a) Nonsense: The nonsense-mediated mRNA decay pathway degrades mRNAs transcribed from genes in which an amino-acid codon has changed to a nonsense codon; this prevents the translation of such mRNAs into...

GENETIC & Molecular BIOLOGY

...Genetics and Molecular Biology Question 2) When looking at two different species, specifically the horse which possesses 64 diploid chromosomes and 36 acrocentric autosomes, and the ass which possesses 62 chromosomes and 22 acrocentric autosomes, it is significant to investigate the genotype of the offspring. If one were to mate a male ass with a female horse, the offspring would be a mule with 63 diploid chromosomes. The reason that the mule (progeny of the ass and horse) has 63 diploid chromosomes is as follows: The male ass has 62 diploid chromosomes and therefore its gametes would contain 31 chromosomes each, after meiosis. The female horse has 64 diploid chromosomes and 32 chromosomes in her...

Eukaryotes/molecular biology

...Introduction Everyone is familiar with eukaryotes primarily because most of the living and visible organisms like plants, animals and human beings are eukaryotes. While a huge diversity in the living forms of eukaryotes can be seen by the naked eyes, there are millions of eukaryotes species that exist on earth but are not visible to the ordinary eyes. Eukaryotes can be defined as organisms whose cells are structurally and functionally complex, bound within a membrane and contain a nucleus. The various parts of eukaryote cells carry out specialized reactions and functions. Eukaryotes vary from single cell amoeba to multi-cellular creature like human-being and dinosaur, which is now extinct. Body The eukaryote cells... Everyone is familiar...

Cell molecular biology

...Cyclin gene TTherm_00425970 expression during conjugation of the ciliate Tetrahymena thermophila The goal of this study was to assess the role of individual cyclin genes of the eukaryotic microorganism, Tetrahymena thermophila, in the process of conguation, a sexual cell division cycle unique to the ciliated protozoans that involves a complex series of events that include meiotic and mitotic nuclear divisions, nuclear fusions, DNA elimination and amplifications and nuclear destruction. Gene expression patterns of the cyclin genes of Tetrahymena are known to both drive and respond to cell cycle events similar to these in other model systems. Microarray expression data for the cyclin genes of Tetrhymena thermophila were collected...

It has been established that molecular data along with morphological data played important roles in giving vivid details on the history of evolution. While it is true that molecular data or DNA data results to documented sequence of various events in the evolutionary development of specific specie, it cannot achieve any success in deciphering the evolution of species that lived hundreds or millions of years ago through fossils. It is in this regard that...

...Molecular Biology and Molecular Diagnostics Introduction The popularity of Health tips magazines is on the rise. The magazines are increasingly being appreciated because of their role of providing useful health information on various topics (Allison, 2009, p. 45). What is more, the magazines offer information on the most recent advances in molecular biology research, the most effective health practices, and beauty tips for (aging) women. Health tips magazines also address emotional, mental, fitness-related, dietary, and physical environment issues. The main topics discussed in health magazines include disease management, fitness, beauty, diet, well...

...LYMPHOMA DIAGNOSTICS TECHNIQUES al Affiliation) Problem of Interest Lymphoma diagnostics. Many people die of the disease called non-Hodgkin’s lymphomas. The most common type of non-Hodgkin’s lymphomas (NHL), out of the many subtypes, is the diffuse large B-cell lymphoma (DLBCL). This death rate can be reduced by employing various methods stated below. Why the Problem Exists It is very difficult to categorize prognostic ally on morphological or clinical grounds the condition of NHL subtype DLBCL. With the complexity of the classification system of the NHL, it is known that the NHL categories have multiple disease subtypes each with separate molecular defects and clinical outcomes. An example is where, 35-40% of patients...

...Molecular Biology Monoclonal antibodies are used in research, diagnostics and therapeutics. Monoclonal antibodies are issued from one single cloneof cells. Monoclonal antibodies from mouse origin are easy to produce but their therapeutic availability is restricted by their antigenicity. Human monoclonal antibodies are produced by humanising mouse monoclonal antibodies. Monoclonal antibodies can be obtained by intraperitoneal injection into mice and collection of ascetic fluid produced. Since it is difficult to to remove antigenicity from the mouse, in vitro immunisation (IVI) protocol of human peripheral blood mononuclear (PBMC) cells for generating human antigen specific antibodies was developed. For monoclonal antibody, mice... Biology...
