Bacterial Classification and Identification Kunle Kassim, PhD, MPH Professor, Microbiology August, 2010. This alternative scheme is presented below and is used in the … Different from parasites and fungi (eukaryotic) •Prokaryotic organisms –simple unicellular organisms –no nuclear membrane –no mitochondria –no Golgi bodies –no endoplastic reticulum •Complex cell wall –Gram-positive –Gram-negative. Classification seeks to describe the diversity of bacterial species by naming and grouping organisms based on similarities. Gram-negative bacteria are more resistant against antibodies because their cell wall is impenetrable. Parasitology is the branch of Science which mainly deals about all the Parasites and its infectious diseases. They constitute the basis for the formal description of taxa, from species and subspecies up to genus and family.

The classical phenotypic characteristics of actinobacteria comprise morphological, physiological, and biochemical features. •It is important for you to review the powerpoint lectures on Bacterial Cell Structure and Bacterial Metabolism from first year before coming to class for this lecture. Fungi are widely distributed in nature (air, water, soil, decaying organic debris). Classification of Bacteria of Medical Importance that give Gram-negative Reaction This classification was carried out in 1986 and placed spirochetes, spiral and curved, aerobic bacteria and facultatively aerobic rods, obligate anaerobic bacteria, aerobic and anaerobic cocci, sulfate and sulfur-reducing, rickettsias, clamydias, and mycoplasmas in this group. Introduction The purpose of this lecture is to introduce you to terminology used in microbiology. Classification. Introduction to the Fungi. ii) Mycology can simply be defined as the study of fungi. Microorganisms can be classified on the basis of cell structure, cellular metabolism, or on differences in cell components such as DNA, fatty acids, pigments, antigens, and quinones. Heterocyst 6. Discuss bacterial structure and the function of the different bacterial components 4. It's a field in which bacteriologists study and learn more about the various characteristics (structure, genetics, biochemistry and ecology etc) of bacteria as well as the mechanism through which they cause diseases in humans and animals.

Introduction to Mycology and Classification of Fungi. Methods of Identification 1. The Bacteria (eubacteria) Bacteria (also known as eubacteria or "true bacteria") are prokaryotic cells that are common in human daily life, encounter many more times than the archaebacteria. Whole Parasitology covers mainly Parasites, Host and its association between them.For having a very clear cut knowledge about Introduction and Classification of Parasites … One advantage of the stained bacteria smear slide over hanging drop slide is bacteria is more visible strained bacteria smear are useful in helping to classify and identify bacteria. Microorganism Speculation Pre-microbiology, the possibility that microorganisms existed was discussed for many centuries before their actual discovery in the 17 th century. Microorganisms: An introduction . URGENT!!!! This bacteria is a gram positive, club-shaped, non-motile bacteria. ii) Introducing 3 types of microbe with fact sheets and a wanted poster. A few different criteria are used to classify bacteria. The traditional phenotypic tests are commonly used in actinobacterial identification. Because of this character, they contribute greatly to humans and the environment. About how long ago did eukaryotes evolve from prokaryotes? Introduction to bacteria, viruses and fungi.

In general, antibiotics kill multidrug-resistant (MDR) bacteria through various mechanisms. Meaning and Characters of Cyanobacteria: The cyanobacteria (the earlier blue-green algae), or the blue-green bacteria, represent a group of photosynthetic, mostly photolysis-mediated oxygen-evolving monerans (prokaryotes). Bacteria obtain nutrition in different forms. Example: -Pseudomonas. 2. Classification of Microorganisms 2. that cause acute diarrhoea (see Vibrio, Campylobacter and Helicobacter).
