27.6 Bаcteriаl Diseаses in HumansBacterial diseases are caused by harmful bacteria that enter the bоdy and cause infectiоns. These infectiоns can range from mild to severe and can affect various parts of the body. Some of the most common bacterial diseases that affect humans include tuberculosis (TB), ulcers, and sexually transmitted diseases (STDs) such as chlamydia, gonorrhea, and syphilis.TB is a bacterial disease that primarily affects the lungs but can also affect other parts of the body. It is spread through the air when an infected person coughs or sneezes. Symptoms of TB include coughing, chest pain, fatigue, and weight loss. TB can be treated with antibiotics, but it requires a long course of treatment to be effective.Ulcers are caused by a type of bacteria called Helicobacter pylori. These bacteria infect the lining of the stomach and small intestine, leading to the formation of sores. Symptoms of ulcers include abdominal pain, bloating, and nausea. Treatment for ulcers usually involves a combination of antibiotics and acid-reducing medications.STDs such as chlamydia, gonorrhea, and syphilis are bacterial infections that are spread through sexual contact. Chlamydia and gonorrhea can cause symptoms such as genital discharge, pain during urination, and abdominal pain. Syphilis can cause a range of symptoms, including sores, rashes, and fever. It's important to note that chlamydia can sometimes be undetected as it is asymptomatic, while gonorrhea and syphilis typically have noticeable symptoms. Recently, there has been an increase in reported cases of chlamydia, which makes it even more important to prioritize regular sexual health checkups and safe sex practices to prevent the spread of these bacterial infections. All of these STDs can be treated with antibiotics, but early detection and treatment are important to prevent long-term complications.In addition to these specific bacterial diseases, there are also bacterial infections that can lead to the development of certain types of cancer. For example, Helicobacter pylori infection has been linked to the development of stomach cancer. While not all bacterial infections are harmful, it is important to take steps to prevent the spread of harmful bacteria and to seek medical attention if you experience any symptoms of infection.
27.3 Prоkаryоtic Genetics Prоkаryotic genetics is the study of the genetic processes thаt occur in prokaryotic organisms. Among the most important genetic mechanisms in prokaryotes are transformation, transduction, conjugation, and antibiotic resistance. Transformation is a process in which a bacterium takes up free DNA from the environment and incorporates it into its own genome. This can lead to the acquisition of new traits, such as antibiotic resistance, virulence factors, or metabolic capabilities. Transformation was first described in Streptococcus pneumoniae by Frederick Griffith in 1928. Transduction is a process in which bacteriophages (viruses that infect bacteria) transfer bacterial DNA from one cell to another. This can occur when a bacteriophage accidentally packages bacterial DNA instead of its own DNA during assembly. When this phage infects another bacterium, it can transfer the foreign DNA into the new host cell. Transduction was discovered by Joshua Lederberg and Norton Zinder in the 1950s. Conjugation is a process in which two bacteria exchange genetic material through a pilus (a thin, hair-like appendage). One bacterium (the donor) transfers DNA to the other (the recipient) through this pilus. Conjugation is often used to transfer plasmids (small, circular DNA molecules) that carry antibiotic resistance genes. Conjugation was first described in Escherichia coli by Joshua Lederberg and Edward Tatum in 1946. Antibiotic resistance is a growing problem in modern medicine, as many bacterial pathogens have acquired the ability to resist multiple antibiotics. This is often due to the acquisition of antibiotic resistance genes through transformation, transduction, or conjugation. These genes can confer resistance to a wide range of antibiotics, making it difficult to treat infections caused by these bacteria. As a result, there is a pressing need to develop new antibiotics and alternative therapies to combat antibiotic-resistant bacteria. Horizontal-gene-transfer-mechanism.jpg
