the subcutaneous inoculation of 16 white mice and 10 golden hamsters with l.tropica major resulted in the development of leishmanial lesions in all, becoming generalized in some.two of 10 hamsters inoculated intraperitoneally with this parasite developed generalized lesions. on the other hand, the inoculation of l. tropica minor to 128 mice subcutaneously and 170 mice intraperitoneally did not ...

conclusions penetrating trauma from wooden fragments provides a diagnostic challenge. a stubborn discharge from a wound must always raise the suspicion of retained fragment. early and appropriate surgical exploration is imperative. introduction in contrast with victims of major trauma, patients who suffer minor injuries receive little specialist input. in most cases, this causes no difficulty, ...

introduction and objective: zinc as the second trace element of the human body plays an important role in numerous functions. a large number of research studies have showed serum zinc deficiency and excess urinary excretion in patients with major beta thalassemia, but few studies revealed excess urinary zinc excretion in minor beta thalassemia and no study investigated serum zinc levels in this...

atl is a newly discovered autolysin gene in Staphylococcus aureus. The gene product, ATL, is a unique, bifunctional protein that has an amidase domain and a glucosaminidase domain. It undergoes proteolytic processing to generate two extracellular peptidoglycan hydrolases, a 59-kDa endo-beta-N-acetylglucosaminidase and a 62-kDa N-acetylmuramyl-L-alanine amidase. It has been suggested that these ...

A gene encoding a putative peptidoglycan hydrolase, named acmB, which is a paralogue of the major autolysin acmA gene, was identified in the Lactococcus lactis genome sequence. The acmB gene is transcribed in L. lactis MG1363 and its expression is modulated during cellular growth. The encoded AcmB protein has a modular structure with three domains: an N-terminal domain, especially rich in Ser, ...
