AKURE‚ ONDO STATE‚ NIGERIA. RETROSPETIVE STUDY OF BOVINE TUBERCULOSIS IN ONDO STATE‚ NIGERIA INTRODUCTION BOVINE TUBERCULOSIS (BTB): Is a chronic infectious and contagious disease of both domestic and wild animals including human (Radostitis et al. 2002). It is characterized by the formation of granulomas in tissues and organs‚ more significantly in the lungs‚ lymph nodes‚ intestines‚ liver and kidneys (Shitaye et al.‚ 2007). Bovine TB is caused by a slowly growing bacillus which is a

Biochemistry of Proteins; Isolation of Ovalbumin and Enumeration of thiol groups Abstract Thiol groups are important to protein folding and forming disulphide bonds that are essential to protein structure. Determining the number of thiol groups in a protein is important in determining the tertiary structure of the protein. The ovalbumin is the experiment was purified from egg white using centrifugation and ammonium sulphate precipitation and then the thiol groups identified using DTNB and spectroscopy

AbstractWater is important substance for all living organisms. The physical and chemical properties of water play a central role in biological structure and function of the organism. The ionization ability of water to form H+ and OH- ions make it very unique. The hydrogen-ion concentration of biological system is usually preferred as the pH system‚ which determines the pH level of dilute aqueous solutions. In this laboratory‚ the data collected from the experiment will be used to graph the titration

Introduction Methionine and cysteine are both sulphur containing amino acids. Most proteins will contain one‚ or both of them at some point in the polypeptide chain. As such‚ many amino acids contain sulphur in some form‚ which is required in small amounts in the mammalian diet. Methionine has a thioether side chain‚ and cysteine’s contains a thiol group. These side chains exist as free thiols inside the cell‚ and are oxidised causing them to pair up and form disulphide bonds in an extracellular

Casco College of DuPage Abstract This paper is a review of the book “Six Modern Plagues and How We Are Causing Them”. Discussing about the causative agents of each plague and how we increased the severity of each; Mad Cow Disease (Bovine spongiform encephalopathy)‚ Human Immunodeficiency Virus/ Acquired Immune Deficiency Syndrome (HIV/AIDS)‚ Salmonella‚ Lyme Disease‚ Hantavirus‚ and West Nile Virus. Millions of people have died because of these diseases that can easily transfer from person to

Transmissible Spongiform Encephalopathies (TSE’s) are an obscure category of diseases caused by infectious proteins‚ or Prions. Despite the unique threat posed by prion infections‚ they are rightfully a low priority concern for medical science because of their rarity. While universally fatal‚ TSE’s in human are rare occurrences that have been effectively been prevented by legislative responses to outbreaks of Mad Cow disease. Instead‚ they provide unique challenges and opportunities to further insight

Lastly‚ there is disease which is the most important effect from factory farming it can have a big impact on the consumers and the animal. One of the many diseases is mad cow diseases it is also known as Bovine spongiform encephalopathy (BSE) is said to be caused by feeding dead cows to other cows; the cow becomes infected and so can humans through the consumption of diseased meat (O’Brien 30). There is something that has to change they could either stop feeding dead cows to cows which they definitely
