E histolytica and E. dispar cannot be differentiated based on
- Zymodemes
- Serology
- Electrophoretic mobility of isoenzymes
- PCR
Serology
Gold standard for community screening of E. histolytica
- Microscopy of unfixed stool
- Ritchie’s fecal concentration
- Staining of alcohol fixed stool
- Robinson’s in vireo culture
- Stool Ag
- Serology - IHAT, ELISA, Immunoflourescence
- Isoenzyme electrophoresis
Isoenzyme electrophoresis and Robinson’s in vitro culture are gold standard
Direct microscopy is more sensitive than serology

Which of the following is not used for treatment of cystobilliary communication
- Ommentoplasty
- Ercp
- Duct ligation
- Hepatectomy
Answer - ercp stenting is not used
The communication can be dealt with resection, ommentoplasty prevents development of fistula in the cavity, opening can be suture ligated
Which of the following is not a treatment option for long lateral injury of cbd
- Cystic duct stump
- Jejunal Pedicle flap
- RnY jejunal serosal patch

- Medical treatment is considered when surgery is not possible
- Ectocyst is not infective
- All of the above
Meniscus sign is seen when bronchioles are eroded and air enters between pericyst and laminated membrane - S/o of imminent rupture
Ans - all are true
Which of the following is not done in lung hydatid ds.
