BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014208543 DESCRIPTION A 13-year-old girl presented to A&E with a 3-day history of abdominal pain, anorexia and nausea. Bowels were opening regularly once daily with no blood or mucous and there were no urinary symptoms. Menstruation was normal; there was no vaginal discharge or bleeding and the pat...

Enterobius vermicular is a parasite can lead to inflammation and symptoms in rare cases however it can manifest as ulceration in colon which may mimic tubercular ulcer. A 40-year-oldman presented with pain abdomen. The pathologic findings confirmed the diagnosis of E. vermicularis in the colonic biopsy. It is important to be aware of this resemblance to avoid unnecessary surgical intervention a...

Male fern has been commonly used for manyyears as an anthelmintic against cestodes, though its administration is very troublesome and even risky to the host. Maplestone and Mukerji (1931) mention trying of tetrachlorethylene in three cases of Tcenia saginata infection with apparently no effect. But their further experience with tetrachlorethylene (Maplestone and Mukerji, 1937) claim the drug as...

Dear Editor, we would like to discuss on the recent publication on false-negative dengue cases. ACOSTA et al. reported that “Health care providers should therefore be aware of samples tested negative by NS1 antigen assays, especially when clinical symptoms and other laboratory data results show evidence of dengue infection”. In fact, the problem of false-negative in dengue diagnosis is an impor...

Staphylococcus sp. is not only a commensal bacterium but also a major human pathogen that causes a wide range of clinical infections, such as skin and soft tissue infection, pleuropulmonary and osteoarticular infection, and endocarditis as well as lifethreatening systemic infections. More evidence is currently emerging to show that Staphylococcus, particularly Staphylococcus aureus, can coloniz...

Human fibroblasts immortalized by Simian Virus 40 (SV40) are widely employed for cell and molecular biology model of study. Indeed, SV40 transmission to humans was believed to occur only under exceptional situations. The oncogenic potential of SV40 in laboratory animals is well established, whereas its involvement in human carcinogenesis is still a matter of active investigations. A recent repo...

BACKGROUND Schistosomiasis is one of the major health problems in tropical and sub-tropical countries, with school age children usually being the most affected group. In 1998 the Department of Health of the province of KwaZulu-Natal established a pilot programme for helminth control that aimed at regularly treating primary school children for schistosome and intestinal helminth infections. This...

On the tropical legume Sesbania rostrata, stem-borne nodules develop after inoculation of adventitious root primordia with the microsymbiont Azorhizobium caulinodans. A cDNA clone, Srchi13, with homology to acidic class III chitinase genes, corresponds to an early nodulin gene with transiently induced expression during nodule ontogeny. Srchi13 transcripts accumulated strongly 2 days after inocu...

BACKGROUND Blood contained in needles and injection equipment has been identified as a vector for HIV and HCV transmission among people who inject drugs (PWID). Yet, there is often a wide discrepancy in prevalence for both viruses. While microbiological differences between viruses influence prevalence, other variables associated with the way drugs are acquired and used, also play a role. METH...
