Do I Need an Antibiotic? Bacterial vs. Viral Infections Posted 24.4. , 201 9 Bacteria vs virus – learn the difference and the best way to fight each. Think a good dose of antibiotics will knock that cold or flu out of you? Think again. Antibiotics, if prescribed and taken correctly, usually can kill bacteria but they are useless against viruses such as the cold and flu. Unlike bacteria, viruses generally require a vaccination to prevent them in the first place or antiviral drugs to treat them. Often, the only treatment for a viral infection is to let the illness run its course. What’s the difference? Bacteria: Mostly friendly Bacteria are single-celled microorganisms that are everywhere— in the air, soil and water, on plants and in animals. Most bacteria—including those in our intestines —are harmless. Some actually help by digesting food and destroying disease-causing microbes, according to the Mayo Clinic, which notes that fewer than 1 percent of bacteria ca...

Differences Between Bacteria and Viruses Last updated: 24.4.2019 ....written by vinod kumar kushwaha Although bacteria and viruses both are very small to be seen without a microscope, there are many differences between Bacteria and Viruses. Some of the Differences Between Bacteria and Viruses are as follows: S.N. Characteristics Bacteria Viruses 1 Size Larger (1000 nm) Smaller (20-400 nm) 2 Cell Wall Peptidoglycan or Lipopolysaccharide No cell wall. Protein coat present instead. 3 Ribosomes Present Absent 4 Number of cells One cell (Unicellular) No cells 5 Living/Non-Living Living organisms Between living and non-living things. 6 DNA and RNA DNA and RNA floating freely in cytoplasm. DNA or RNA enclosed inside a coat of protein. 7 Infection Localized Systemic 8 Reproduce Able to reproduce by itself Need a living cell to reproduce 9 Reproduction Fission- a form of asexual reproduction Invades a host cell and takes over the cell causing it to make copies of...

New Enzyme To Arrest Bacterial Growth Discovered By CCMB Scientists Written on 04/23/2019 New Enzyme To Arrest Bacterial Growth Discovered By CCMB Scientists Center for Cellular & Molecular Biology (CCMB) Scientists has found a new enzyme which helps in breaking cell walls of bacteria and consequently, offers a potential for a new drug delivery route to arrest the anti-bacterial resistance through existing antibiotic drugs. In a press conference held on Tuesday, CCMB Director Rakesh Mishra and Seniors scientist Manjula Reddy explained – that for research it is vital to understand how the cells grow in bacteria to comprehend the resistance to antibiotics that were currently available. Scientists all around the world are trying to understand this phenomenon. Dr. Reddy Labs has been analyzing the way e.coli bacteria cells operate, split and grow to understand diseases like cholera, leprosy, tuberculosis and so on. Dr. Reddy along with her research scholar Ch. P...

Brain marker for angry dreams Sleep study advances understanding of emotions experienced during dreaming Date: April 22, 2019 Source: Society for Neuroscience Summary: Researchers have identified a pattern of brain activity that predicts anger experienced during dreaming, according to a new study of healthy adults. The research could potentially inform efforts to understand the neural basis of the emotional content of nightmares, a feature of various mental and sleep disorders.   Researchers have identified a pattern of brain activity that predicts anger experienced during dreaming, according to a new study of healthy adults published in  JNeurosci . The research could potentially inform efforts to understand the neural basis of the emotional content of nightmares, a feature of various mental and sleep disorders Although emotions are experienced during both waking and dreaming, few studies have investigated the brain mechanisms underlying the affective c...
