conclusions it is concluded that cryptosporidium spp. should be considered in immunocompromised diarrheal patients and elisa must be chosen for detection of this parasite. modified acid fast staining and cassette kit techniques could be performed if elisa is not available. the single use of the cassette kit will be inadequate for the diagnosis of cryptosporidiosis. background cryptosporidiosis ...

Understanding what determines the host range of pathogens and the potential for host shifts is of critical importance to controlling their introductions into new environments. The phylogeny of the hosts has been shown to be important: pathogens are more likely to be infectious on hosts closely related to their host-of-origin because of the similar host environments that is shared by descent. Th...

Background: Interleukie-8 is a proinflammatory cytokine and a potent chemotactic and activation factor for neutrophils. It has been reported to be expressed in high levels by various cell types after immune stimulation and mediates neutrophil recruitment in host. Objectives: The aim of this study was to analysis of the relationship between single nucleotide polymorphisms (SNPs) at position -18...

Binding studies between the electron accepting host cyclobis(paraquat-p-phenylene) and a series of electron donors in the presence of differently sized counteranions reveal that both the nature and the concentration of the anion have a large impact on the association strength of the resulting host-guest complex.
