Hygiene - Viruses, Bacteria, and Parasites Hygiene-Viruses, Bacteria, and Parasites. Diseases can be classified as genetic, metabolic, or infectious. Genetic diseases are caused by genetic defects inherited from the parents. Sickle cell anemia and cystic fibrosis are two examples of genetic diseases. Many viral, bacterial, and protozoan diseases are transmitted by insect bites from mosquitoes, flies, fleas, and ticks. 2  Diseases transmitted by mosquitoes include Dengue Fever, Malaria, Rift Valley Fever, Yellow Fever, and various types of viral encephalitis such as West Nile virus.

Inheritance and Genetics of Helicobacter pylori bacteria Genetics of Helicobacter pylori bacteria: Helicobacter pylori bacteria is NOT a genetic disease. Helicobacter pylori bacteria is an infectious disease.In general, an infectious disease can be caused by a pathogenic organism (viruses, bacteria, fungi, worms, parasites) that can invade the body and cause infection.bout inheritance and genetics: Inheritance of Helicobacter pylori bacteria refers to whether the condition is inherited from your parents or runs in families. The level of inheritance of a condition depends on how important genetics are to the disease.

Cell Biology/Cell types/Prokaryotes Conjugation and Plasmids In a process called conjugation, genetic material is transferred between two bacterial cells (of same or different species) that are temporarily joined. The DNA transfer is one way: One cell donates the DNA,a nd the other receives ti.The donor uses sex pili to attach to the recipient.he cell is now a recombinant: Its chromosome contains DNA derived from two different cells. In transduction, bacteriophage carry bacterial genes from one hose cell to another; transduction is a type of horizontal gene transfer.

- Transfer of DNA from a donor to a recipient by direct physical contact between the cells. In bacteria there are two mating types a donor (male) and a recipient (female) and the direction of transfer of genetic material is one way; DNA is transferred from a donor to a recipient.ene transfer in bacteria is unidirectional from a donor cell to a recipient cell and the donor usually gives only a small part of its DNA to the recipient. Thus, complete zygotes are not formed; rather, partial zygotes (merozygotes) are formed.

Some Organisms Transmit Genetic Material to Offspring without Cell Division Transduction occurs when a bacteriophage containing bacterial DNA infects a recipient bacterium and transfers this bacterial DNA to the recipient bacterial host cell. This transferred bacterial DNA may then be incorporated into the genome of the recipient bacterium.

- Bacteria divide by binary fission which simply means that one cell splits in two. As a separate matter, there is a process called conjugation for transfer of genetic information that is completely different than binary fission. The bacterial organism would then start to divide and multiply. Some bacteria can form spores when it cannot survive very well (such as in freezing temperature) and then take off the spore barrier when multiplication and feeding conditions are better.

- Corynebacterium diphtheriae is the causative agent of diphtheria. Diphtheria bacteria are Gram-positive, pleomorphic, often club-shaped rods.The individual cells tend to group in V, Y, or palisade arrangements (see figure). Humans are the sole pathogen reservoir for diphtheria.Infection sources include infected persons and carriers (rare). The disease is usually transmitted by droplet infection, or less frequent indirectly via contaminated objects. Infected are the mucosa of tonsils, pharynx, nose and conjunctiva.umans are the sole pathogen reservoir for diphtheria. Infection sources include infected persons and carriers (rare).

Horizontal Gene Transfer: Definition & Process This kind of gene transfer can even occur between members of different domains: the eukaryota, bacteria and archaea. It's called horizontal gene transfer. Let's go over it. Horizontal Gene Transfer. Horizontal gene transfer, also known as lateral gene transfer, is the transmission of genetic material from one genome to another genome in a way other than reproduction. How can this be so? Well, there's actually more than one way, and I'm going to give you a concrete example.

Genetics: Ch. 8 Two differences between process of genetic exchange in bacteria from diploid eukaryotic sexual reproduction: 1.) DNA exchange and reproduction are not coupled in bacteria 2.) donated genetic material that is not recombined into the host DNA is usually degraded, and so the recipient cell remains haploid.

Bacteria and Viruses Transduction. Transduction is the process by which DNA is transferred from one bacterium to another by a virus. It also refers to the process whereby foreign DNA is introduced into another cell via a viral vector.eneralized transduction is the process by which any bacterial gene may be transferred to another bacterium via a bacteriophage, and typically carries only bacterial DNA and no viral DNA. In essence, this is the packaging of bacterial DNA into a viral envelope.

Bacteria Some bacteria also transfer genetic material between cells. This can occur in three main ways. First, bacteria can take up exogenous DNA from their environment, in a process called transformation. Many bacteria can naturally take up DNA from the environment, while others must be chemically altered in order to induce them to take up DNA.

- In nature, bacteria can transfer plasmids back and forth, allowing them to share these beneficial. genes. This natural mechanism allows bacteria to adapt to new environments. The recent. occurrence of bacterial resistance to antibiotics is due to the transmission of plasmids. Bio-Rad’s unique pGLO plasmid contains the gene for GFP and a gene for resistance to the. antibiotic ampicillin.

- Smaller circular auxiliary DNA strands, called plasmids, are also found in the cytoplasm. Pili-Many species of bacteria have pili (singular, pilus), small hairlike projections emerging from the outside cell surface.ike the chromosome, plasmids are made of a circular piece of DNA. Unlike the chromosome, they are not involved in reproduction. Only the chromosome has the genetic instructions for initiating and carrying out cell division, or binary fission, the primary means of reproduction in bacteria.

- In order to infect a host cell, the bacteriophage attaches itself to the bacteria’s cell wall, specifically on a receptor found on the bacteria’s surface. Once it becomes tightly bound to the cell, the bacterial virus injects its genetic material (its nucleic acid) into the host cell.nce the host cell is infected, the phage DNA integrates or combines with the bacterial chromosome, creating the prophage. When the bacterium reproduces, the prophage is replicated along with the host chromosomes. Thus, the daughter cells also contain the prophage which carries the potential of producing phages.

Prokaryote Bacteria and archaea reproduce through asexual reproduction, usually by binary fission. Genetic exchange and recombination still occur, but this is a form of horizontal gene transfer and is not a replicative process, simply involving the transference of DNA between two cells, as in bacterial conjugation.
