Dear Editor,

The case report, 'Infected primary hydatid cyst located in Sartorius muscle' makes an interesting reading. [1] The photographs are good. It is a rare finding as stated by the authors since contractility and high lactic acid content of muscle do not allow the larvae to survive in muscle. Moreover, there are effective hepatic and pulmonary barriers. Predominant localization in the muscles of lower limb could be explained by the volume of muscle mass and rich blood supply. [2] However, there are few suggestions and details that need to be addressed.

The first line of introduction states it to be a protozoan infestation. Echinococcus granulosus is a helminth, metazoan and cestode. The cyst was infected. Authors have not mentioned the culture report and names of the preoperative antimicrobials used for two weeks. As clinical microbiologists, we are interested.

A wet mount microscopy of the centrifuged deposit of cyst fluid post surgery and examination of hydatid sand could have revealed the protoscolices and hooklets. It is simple and could have been done along with the histopathology. Hydatid sand is so-called because of the gritty feeling it gives when a drop of hydatid fluid is rubbed between two slides. [3] Eosin stain of cyst fluid can differentiate the dead protoscolices which take the stain from live ones which remain unstained. [4] The findings in images need arrows to point out the exact location. They are radiological and imaging diagnosis, difficult to decipher for a microbiologist. The patient's association with live stock, sheep and cattle is shown but there is no mention of dogs. Canines are the optimum definitive host of hydatid sand, and dog faeces containing the eggs are the common source of infection. The magnitude of the problem is clear by the fact that World Health Organization included Echinococcosis as part of Neglected Zoonotic Diseases for its 2008-2015 strategic plan for the control of neglected tropical diseases. [5]
