Natural environments contain a variety of microorganisms, of which, a limited number are able to develop bioremediation process. The main goal of the present paper was to perform microbiological investigations to culturable bacteria isolated from uranium ore samples from Aborshid Egypt, and characterize their response to 15 antibiotics and 10 heavy metals beside uranium. Among the potential environmental isolates, there was no detection of any acquired antibiotic resistance, which supports the idea that their resistance mechanisms are mainly intrinsic. On the contrary, the potentially pathogenic isolates presented a broad diversity of acquired antibiotic resistance toward different antibiotic classes. Furthermore, results revealed a varying response of the ore bacteria to the tested heavy metals. All isolates showed multiple metal resistances toward 10 heavy metals, with MIC ranging from 50 to 1000 ppm. We found that optimum temperature for growth of bacteria in general ranges from 30 to 50 °C and bio-sorption of metal increased with increasing pH from 1.0 to 5.0, then decreased upon further increase to 7.0. The decrease in the sorption efficiency at pH higher than 5.0 may be due to the precipitation as hydroxide. We found possible correlation between antibiotic resistance and heavy-metal resistance patterns of Escherichia coli strains isolated from uranium ore; the most potent of the strains in both groups were resistant to Pb, Ni, Cu and Zn. It was concluded that highly metal-resistant bacteria could be used with potential application for treatment of wastewaters.

Bocktor, "The impact of l-arginine supplementation on the enteral phase of experimental infection in treated and untreated mice.", Journal of parasitic diseases : official organ of the Indian Society for Parasitology, vol. 44, issue 4, pp. 737-747, 2020. Abstract

The role of nitric oxide (NO) in the immunopathological response during () infection remains controversial. The amino acid, l-arginine is a NO precursor commonly used by athletes and bodybuilders as a protein supplement. As to our knowledge, there are no published studies which have tested the effect of l-arginine on the intestinal phase of experimental trichinellosis. The present work aims to investigate the effect of l-arginine on the enteral phase of experimental infection in albendazole-treated and untreated mice. Forty BALB/C mice infected orally with larvae were divided into 4 groups as follows: Group A were infected and untreated (control) mice, Group B received albendazole alone, Group C received l-arginine alone, and Group D received both l-arginine and albendazole. Compared to the control group, l-arginine supplementation showed; a significant increase in the intestinal adult worm burden, a significantly high inducible NO synthase (iNOS) expression, elevated immune markers; tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ), and enhanced apoptosis. Albendazole treated-group had a significant reduction in the adult worm number (90.9%), while combined albendazole-arginine regimen showed a lower percentage of worm reduction (72.7%). During the enteral phase of infection, l-arginine supplementation should be taken cautiously, as it may modulate the proinflammatory immune response and subsequently affect the outcome of the infection and/or treatment.


Schistosomiasis is one of the major public health diseases that induced a diversity of immuno-
logic reactions. Significant association between autoreactive antibodies and autoimmune disor-
ders was suggested. This study investigated the presence of anti-double stranded DNA (anti-ds DNA) antibodies and inflammatory biomarker, C-reactive protein (CRP) in 89 Egyptian pa-
tients, with Schistosoma mansoni clinical evidence and high anti-Schistosoma antibody titer. The
results showed positive serum anti-ds DNA antibodies in 11/89(12.4%) of them, without signifi-
cance to age, sex or anti-Schistosoma antibody titers. CRP was positive in 20/89(22.5%) of pat-
ients, with significant correlation with anti-ds DNA antibodies (P=0.000).
Keywords: Egypt, Schistosoma mansoni-anti-ds DNA- CRP- autoimmune disease.

Pediatric kidney transplantation is a multidisciplinary therapy that needs special consideration and experience. In this study, we aimed to present CUCH experience; over a 10-year period, as a specialized center of kidney transplantation in children. We studied 148 transplantations performed at a single center from 2009 to 2018. Pretransplant and follow-up data were collected and graft/patient survival rates were evaluated. A total of 48 patients developed at least one rejection episode during 688 patient-years of follow-up. Infections, recurrence of original disease, and malignancy were the most important encountered medical complications (20%, 2%, and 1.4%, respectively). One-year patient survival was 94.1%, while graft and patient survival was 91.9%. Graft/patient survival at 5, 7, and 9 years was 90%, 77%, and 58%, respectively. Infections were the main cause (69%) of mortality. Death with a functioning graft and CR were the main causes of graft loss (48% and 33%, respectively). Pediatric kidney transplantation in Egypt is still a challenging yet successful experience. Rejections and infections are the most frequent complications. Short-term outcomes surpass long-term ones and graft survival rates are similar to the international standard.
