RESUMEN
Two distinct nodules developed in a cryptorchid testis of an 8-year-old male West Highland White Terrier. One nodule was a Sertoli cell tumor. The other was a spermatocytic seminoma with focal primitive neuroectodermal differentiation: formation of Homer-Wright rosettes and perivascular pseudorosettes, with immunoreactivity for S-100 protein, neuron-specific enolase, synaptophysin, neurofilament-68 kDa, microtubule-associated protein 2, and vimentin. The dog was alive and healthy 2 years after castration.

It is important to evaluate the prevention of nosocomial infections caused by airborne micro-organisms in healthcare facilities. For that purpose, the use of an air sampler is required. A comparison of the collecting efficiency of air samplers has not been studied so far using a single culture medium. Use of the same culture medium is necessary because of the variation of the cultivation efficiency with different culture media. In this study a statistically significant difference in collecting efficiency among air samplers was observed in case of SCDA (soybean casein digest agar) culture medium, but not SCDALP (soybean casein digest agar lecithin polysorbate) culture medium. In addition, a statistically significant difference of the cultivation efficiency was observed between SCDA and SCDALP culture media (P<0.05). These results suggest that any air sampler can be used with SCDALP culture medium.
