RESUMO
Viable protoscolices of Echinococcus granulosus injected into Swiss-albino mice by two different routes, viz. intraperitoneal and subcutaneous and in two different concentrations of 2000 and 1000 scolices, to observe the development of cysts have shown that subcutaneous route of infecting a mouse model is superior because of its low infecting dose and longer survival period of mouse. This finding should be helpful in experiments to observe the effect of drugs for the treatment of hydatidosis, in vivo, without the need of killing the mouse.

One hundred and twenty methicillin resistant Staphylococcus aureus (MRSA) strains were checked for minimum inhibitory concenteration (MIC) of vancomycin. The results showed that 98 strains (81.7 %) had MIC < 4microg/mL, 18 strains (15 %) had MIC 8 microg/mL, and 4 (03.3%) had MIC 16 microg/mL which being borderline between sensitive (< 4microg/mL) and resistant (>32 microg/mL) values points towards possible emergence of low level vancomycin resistance in the organisms and may explain the reasons of delayed therapeutic success of vancomycin in S. aureus bacteraemia in some situations.
