Acid fast organisms... your reign of terror is over!

Enough is enough. I can't take this no more. After years of experiencing terrorism by Microbiology, today I have decided to return the favor. I am going to terrorize this subject by conquering one topic at a time. Today let's conquer acid fast organisms. These are those cells that stain red with Ziehl Neelsen stain.

If a heart meets with an accident in a round (coccus) road and its leg gets hurt, it would start crying. Wouldn't it?

The above image may help us to remember the following four acid fast organisms:
  1. Heart === Nocardia
  2. Round road === Rhodococcus
  3. Leg === Legionella
  4. Cry === Cryptosporidium parvum cyst

After admission to the hospital, the heart has SEPSIS

Streptococcus
Enterococcus
Pneumococcus
Staphylococcus
Isospora belli
Sarcocystis

Later it was found that the sepsis was due to
BAD CLAM

  • Botulism 
  • Anthrax
  • Diphtheria
  • Clostridium
  • Corynebacterium
  • Listeria
  • Monocytogenes

Others that stain with Ziehl Neelsen stain are as follows:

Bismuth poisoning


 Lead poisoning


 Tetanus


 Taenia saginata


 Hydatid cysts

What is a stomach with a leather bottle and signet ring called?

A man wearing a Signet ring and drinking from a leather bottle would probably be a man from medieval era. However the same cannot be told about stomach having a leather bottle appearance and Signet ring cells . Such a stomach is said to be cancerous, most commonly of the adenocarcinoma type. In order to diagnose the diffuse type of adeno gastic carcinoma an endoscopy followed by microscopic examination of the sample are performed. During endoscopy the stomach looks like a leather bottle and under the microscope signet ring cells make an appearance.  What could possibly be the reason behind these characteristic features? The leather bottle appearance is due to the thick and rigid stomach wall due to tumor infiltrating the submucosa. The Signet ring like appearance of the cells is due to mucin filled vacuoles pushing the nucleus to one side. (FYI - the other type of gastric Ca is the Intestinal type which has better prognosis and does not show the above m...

Puddle sign... What's that?

Puddle is a small pool of fluid. Similarly   P uddle sign  is found when a pool of fluid gets accumulated in the peritoneal cavity ( ASCITES ). This  auscultatory sign   can successfully detect as less as  120 ml  of  free fluid in the abdomen.  On the other hand the two signs of percussion and palpation, namely  shifting dullness  and  fluid thrill  are elucited when the peritoneal fluid volume is more than  500 ml  and  1500 ml  respectively. " Like the silence before the storm, there is dullness before the thrill ." Let us presume that we have a patient with ascites and we are required to perform a diagnostic paracentesis (25ml fluid withdrawn using 5ml syringe). What are we required to look at? Color : Clear or cloudy yellow : Normal/TB Straw colored : Cirrhosis, Cancer (Ca), CHF, Nephrotic syndrome Bloody : Ca, TB, Pancreatic (Contain RBCs) Milky (Chy...
