The recurrent evolutionary emergence of asexual lineages within sexual zoo- and anthropophilic dermatophyte species living in animal-frequented soil is likely to be triggered by changes in ecological niche, i.e., shifts of host animal. Subsequent adaptation to the new host species is noted. Sometimes geographic isolation or intrinsic host factors like human race may also play a role in speciati...

This study was conducted to investigate the prevalence of Cryptosporidium spp. in children (n=760) with diarrhea aged 1 month to 13 years, living in urban areas (n=234), rural areas (n=394) and refugee camps (n=132). Samples were collected, stained by modified acid fast stain, and examined microscopically for oocysts. The overall prevalence was 11.6% (88/760). The prevalence was higher in refug...

The relative legibilities of common words typewritten in all-uppercase and all-lowercase letters were studied in three experiments. Human subjects identified the words shown one at a time for a short period. All-uppercase printing was found to be significantly more legible than all-lowercase in all three experiments. The "word-form" of all-lowercase words was not found to to influence word iden...
