#me@:Bacteria is divided into Gram positive and Gram negative based on their ability to trap crystal violet . Gram positive stains purple/blue. Gram negative stains pink/red. What underlies the principle of Gram staining? Gram positive bacteria has many layers of peptidoglycan in its cell wall. Gram negative bacteria has only one layer of peptidoglycan in its cell wall. Make your smear. Fix your smear with 95% methanol, it dries. Then you flood with crystal violet...both Gram positive and Gram negative absorbs the crystal violet. Then flood with iodine. Wash off. And 'decolourise' with 95% alcohol. Finally , a red dye called sufranin is used to stain the smear. Gram positive bacteria has more peptidoglycan than lipid in its cell wall. So it will trap the crystal violet. And will not be decolourised by alcohol. It will retain the original purple/blue colour of crystal violet. Hence, the purple/blue colour. Gram negative bacteria has more lipid than peptidoglycan in its wall. So alcohol will wash off the outer layer of the bacterial cell wall...thus decolourising the crystal violet. . Gram negative bacteria can now pick up the red colour of sufranin dye. Hence, red/pink. |
hillsnite: sir,wah r d possible cure/medication dat can b given to a person sufferin 4rm typhoid?Management of typhoid fever can be medical and/or surgical. Medical management include : 1 )proper fluid and electrolyte monitoring and replacement 2) pharmacologic therapy (broad spectrum antibiotics) prior to isolation of offending organism (S.typhi in this case) 3) patient should be advised on proper hygiene, proper hand washing before eating, proper waste and faeces disposal Surgical management comes in when complications of typhoid fever arise. A good example is intestinal perforation. In cases of multiple small intestinal perforation secondary to typhoid fever, small bowel resection is indicated. |
Gold standard for diagnosis of typhoid fever is culture of isolated organism. Culture is 100% specific. Blood culture, stool culture, culture of bone marrow aspirate. Widal test is not specific or sensitive for typhoid fever. Bless ![]() |
Lagusta: typhoid fever is a serious illness caused by species of salmonella, mainly salmonella typhi, others include s. paratyphi A, B and C strains..... all are gram negative. rods!!!I just remembered one of my in course questions in medical microbiology.. "widal test is not a specific and conclusive laboratory diagnostic test for typhoid fever. discuss" ![]() |
Dr_Bode: From edu to love!Marriage is beyond MBBS and fellowships. If you love her, wife her. ![]() |

And did I add that Medscape has a tab for differential diagnosis for every disorder? During my case presentations, it really helps me to rule out stuff intelligently. It's always cute when I'm presenting and a consultant stops me halfway to ask " why did you ask so so and so?'' And I flash that 'medscape' smile way I don derive tight differentials. It's a must-have |
Lagusta: Yeah, but haven't ever used it, maybe when I subscribe!!!Medscape is the stuffiest app ever for medicine. There's nothing in medicine you won't find there properly dealt with...conditions, drugs, references, procedures. Na wetin I dey carry shine Then there's this app Merck's Manual. It's a paid app though. Its equally good. There's Schwartz Manual of Surgery. A bit stuffy on the surgery side. Haven't had time for surgery in a while. |
Lagusta: na Wa ooo, na love una dey share, not medical apps again!!!uhmmm.. You have Medscape? |
