hello everyone welcome to Monu tutorial academy. • today our topic is gram negative COCCI so first we will discuss about what is Gram negative bacteria and then we also study definition in easy way so you watch full video at till end. and learn everything in this gram negative COCCI video if you any doubt in this video so you ask me in comment box then I replied in shortly time. your doubt in any subject like hematology, microbiology then you tell me in comment box also. • • I will make also the hematology subject video many times so I given below the link of hematology playlist so you can touch and go on playlist on hematology 👇👇👇👇 • • hematology • Theory of Gram negative cocci :- • Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the gram-staining method of bacterial differentiation.[1] They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane. • • Microscopic image of gram-negative Pseudomonas aeruginosa bacteria (pink-red rods) • Gram-negative bacteria are found everywhere, in virtually all environments on Earth that support life. The gram-negative bacteria include the model organism Escherichia coli, as well as many pathogenic bacteria, such as Pseudomonas aeruginosa, Chlamydia trachomatis, and Yersinia pestis. They are an important medical challenge, as their outer membrane protects them from many antibiotics (including penicillin); detergents that would normally damage the peptidoglycans of the (inner) cell membrane; and lysozyme, an antimicrobial enzyme produced by animals that forms part of the innate immune system. Additionally, the outer leaflet of this membrane comprises a complex lipopolysaccharide (LPS) whose lipid A component can cause a toxic reaction when these bacteria are lysed by immune cells. This toxic reaction can include fever, an increased respiratory rate, and low blood pressure—a life-threatening condition known as septic shock.[2] • Several classes of antibiotics have been designed to target gram-negative bacteria, including aminopenicillins, ureidopenicillins, cephalosporins, beta-lactam-betalactamase inhibitor combinations (e.g. piperacillin-tazobactam), Folate antagonists, quinolones, and carbapenems. Many of these antibiotics also cover gram-positive organisms. The drugs that specifically target gram negative organisms include aminoglycosides, monobactams (aztreonam) and ciprofloxacin. • • #monututorialsacademy • #microbiology • #dmlt
