BACKGROUND The role of opportunistic infections in accelerating disease progression in HIV-positive individuals, leading to quick death, is still receiving serious attention. The objective of this study was to determine the prevalence of Isospora belli infections in HIV-positive patients in Edo State, Nigeria between August 2007 and March 2008. METHODS A total of 268 samples from HIV-positive...

Cystoisospora belli, formerly Isospora belli, as an opportunistic infection agent, is seen in immunocompromised patients like HTLV-1. We describe here cystoisosporiasis in an HTLV1 Iranian female in Mashhad, northwestern Iran in 2012 who presented with a debilitating diarrheal illness and great weight loss. C. belli was detected in her stool by modified acid-fast staining and then by molecular ...

Abstract Asteraceae family is as an interesting target for researching natural alternatives crop protection. Many species from this grow weeds, and some of them can influence the development other by allelopathy phenomenon. This paper aimed to review literature main genera with allelopathic or phytotoxic potential, well classes secondary metabolites present in responsible such activity. Artemis...

It is well known that the addition of saliva to blood will accelerate its coagulation (1, 2, 7). This property of saliva is not species specific. It has been shown that dog, cat and human saliva will indiscriminately accelerate the clotting of blood obtained from the dog, cat, cow or man (1, 7). Bellis, Birnbaum and Scott (1) noted that while the clotting factor of saliva was stable at 60 " , i...

Despite the high biodiversity in Mediterranean region, use of wildflowers from mountain areas urban landscaping projects is hampered by limited information on their seed germination performances. This research evaluated traits 14 native herbaceous wildflower species northern west Italian alpine and subalpine areas. Seed Petri dishes at 25 °C was performed, applying two different photoperiod con...

We have used mitochondrial 12S rRNA, 16S rRNA and nuclear beta-fibrinogen (intron 7) sequences to investigate the phylogenetic and phylogeographic relationships between Acanthodactylus erythrurus group species (except for A. boueti). The phylogenetic analyses of the Acanthodactylus genus did not cluster A. guineensis and A. savignyi with the remaining species of the group (A. blanci, A. lineoma...

Enteric pathogens associated with chronic diarrhoea in HIV-positive patients were studied . The study was conducted during January 1995-December 1998. Stool specimens from all diarrhoea patients (n=26) were examined microscopically for ova and parasites using wet preparations and stained smears. Stool samples from diarrhoea patients were also cultured on appropriate media to isolate enteric bac...
