Introduction Identifying unknown bacterium is not only vital to microbiology, but also to the medical and pharmaceutical industries in order to treat disease/infection properly. Bacteria are classified and identified to distinguish among strains and to group them by criteria of interest (1). There are several different procedures that can be utilized to identify a bacterium. This includes the oxidation test, gram stain, and catalase test. The purpose of this lab report is to show the…

Streptococcus is a genus of non-motile gram-positive cocci classified by serological types (Lancefield groups A through T), by hemolytic action (a, B, Y) when grown on blood agar, and by reaction to bacterial viruses (phage types 1 to 86). The various species occur in pairs, short chains, and chains. Some are facultative aerobes, and some are anaerobic. Some species also are hemolytic, and others are non-hemolytic. Many species cause disease in humans. Streptococcus faecalis, a…

Introduction: The African lungfishes are eel or salamander-like freshwater fishes belonging to the genus Protopterus that constitutes of four species that are all found in Africa. The genus Protopterus is the only genus affiliated to the family Protopteridae. The lifespan of lungfishes is about 20 years and more especially under favorable conditions. African lungfish are characterized by their outstanding adaptations that enabled them estivate during dry season. The species is also known by…

reptiles that lived in our oceans 160 million years ago, during the Jurassic period. Paleontologists discovered the first fossils in the early 1800s, far before dinosaurs were ever discovered. This genus evolved from animals that lived on land. They had more than eighty different species in their genus. One species of the ichthyosaurs is the Ophthalmosaurus. As an adult, this creature was two times the size of a human with a tooth filled snout. Although they got to be this size, the…

1. INTRODUCTION 17 18 The genus Camptotheca, including the two tree species C. acuminata(Chinese Happytree) and C. lowreyana[1], is of 19 great medicinal importance because it provides effective medicines against various forms of cancer [2-4]. Some 20 taxonomical studies include the genus in the Cornaceae or Cornaceae s.l. family [5-7], whereas others place it - together 21 with the genus Nyssaand often also with Davidia- in a separate Nyssaceae family [1, 2, 8, 9].…

The most notable thing about Homo naledi is the way it was found and also where it was found. In 2013, two explorers spotted some fossils in a remote cave that was inside the Rising Star cave system, just outside Johannesburg, South Africa. The cave, where the remains were found, was about 30 meters below the surface and was only accessible by going through more than 80 meters of narrow passages. As of 2015, 1550 fossil fragments have been discovered belonging to at least fifteen people, all…

Introduction The proper identification of microbes is an important practice in the medical field as well as other areas of research. Isolation of microbes from a mixed culture broth was performed with the finding of two different microbes; Escherichia coli and Sporosarcina ureae. The isolation process was performed by streaking a mixed culture onto a nutrient agar plate, then transferring the isolated cultures after incubation for biochemical testing. S. ureae is discussed below. Biography…

Orthopoxvirus genus is extremely virulent, and has a fatality rate of nearly 30%. While this virus only attacks a human host, similar members of the Voxviridae family produce similar infections in animals. Transmission of the variola virus requires face-to-face contact via aerosol transmission, as the pathogen cannot survive for long in normal environmental conditions and does not exist in a carrier state. This virus enters a human host most commonly…

dangerous and a community health concern. Adults however will present with a mild grade temperature, headache, conjunctivitis, malaise or coryza. Causative organism: Rubella virus (family Togaviridae, genus Rubivirus)/ Complications Caused by the rubella virus of the family Togoviridae, and genus Rubivirus it is most harmful to the unborn fetus. Congenital rubella syndrome (CRS) affects infants born to women infected by rubella. Highest risk for fetus is the initial ten weeks of…

Introduction Over thousands of microorganisms discovered cause human diseases. One of the infectious microorganisms is the spirochete bacterium Borrelia burgdorferi, which belongs to the genus Borrelia and family Spirochaetaceae. According to the National Institute of Allergy and Infectious Diseases (NIAID), B. burgdorferi was first isolated in 1982 by a zoologist and microbiologist Willy Burgdorfer, Ph.D., thus the name burgdorferi. Lyme disease, which is caused by the bacterium B. burgdorferi…
