During the last four years, an increasing number of cattle herds were classified positive by brucellosis screening tests in areas of Belgium and France free of the disease. No clinical symptom of brucellosis was reported in these animals and no Brucella abortus strains were isolated. After two years, no brucellosis outbreak was registered in all of the herds concerned. On this basis, all the serological reactions observed were classified as false positive. An ELISA using Yersinia Outer membrane Proteins (YOPs) as antigens was developed in order to discriminate between a Yersinia enterocolitica O:9 infection and a Brucella abortus infection. Antibodies against YOPs were detected in sera from Y. enterocolitica O:9 experimentally infected cattle (n = 4) but not in sera from B. abortus experimentally infected cattle (n = 4). In a field study, 66.7% of the 174 serum samples from cattle presenting false positive serological reactions showed anti-YOPs antibodies whereas only 10% of 454 sera, classified negative by the brucellosis screening tests, showed anti-YOPs antibodies. Our results suggest that infections with Y. enterocolitica O:9 may cause false positive reactions in brucellosis testing. [less ▲]

BACKGROUND: Despite a reduction in the magnitude of endemic malaria reported in recent years, malaria and protein-energy malnutrition (PEM) still remain major causes of morbidity and mortality in sub-Saharan Africa among children under five. The relationship between malaria and malnutrition remains a topic of controversy. We aimed to investigate malaria infection according to nutritional status in a community-based survey. METHODS: A cohort of 790 children aged 6 to 59 months and residing in eastern Democratic Republic of the Congo was followed-up from April 2009 to March 2010 with monthly visits. Data on nutritional status, morbidity between visits, use of insecticide-treated nets and malaria parasitemia were collected at each visit. The Z scores height for age, weight for age and weight for height were computed using the reference population defined by the WHO in 2006. Thresholds for Z scores were defined at -3 and -2. A binary logistic model of the generalized estimating equation (GEE) was used to quantify the association between PEM indicators and malaria parasitemia. Odds ratio (OR) and their 95% confidence interval (95% CI) were computed. RESULTS: After adjustment for season, children with severe stunting (height for age Z score<-3) were at lower risk of malaria parasitemia greater or equal to 5000 trophozoits/μL of blood as compared to those in with a better nutritional status (height for age Z score≥-2) (OR=0.48, 95% CI: 0.25-0.91). CONCLUSION: Severely stunted children are at a lower risk of high-level malaria parasitemia. [less ▲]

Purpose : With the development of antiretroviral therapy, Human Immunodeficiency Virus (HIV) infection has become a chronic disease. In order to develop an efficient response to this new challenge, there is a need for closer collaboration between specialized units and general practitioners. This article identifies the opportunities for and the barriers to this collaboration. Methods : Semi-structured interviews were conducted with patients living with HIV, general practitioners working in multidisciplinary group practice using the capitation system and infectiologists from one Belgian urban area. Interviews focused on experiences and expectations in relation to diagnosis, follow-up and collaboration between general practitioners and infectiologists. Results : Overall, infectiologists and general practitioners aspire to improved communication and collaboration. There are overlaps between general practitioner’s and infectiologist’s field of action. The general practitioner’s intervention is sometimes restricted to common uncomplicated or psychosocial problems, in the context of unplanned and short contacts. Infectiologists prefer to focus on HIV problems, leaving general practitioners to take care of these patients’ other health problems. The patient may be an obstacle to greater involvement of general practitioners due to fear of stigmatization from his family and social circle or lack of confidence in the general practitioner’s skills. Conclusion : This research underlines the difficulties and gaps in the care of HIV patients and provides preliminary explanations for the lack of active cooperation between general practitioners and infectiologists. Overlaps between the areas of professional skills can result in uncovered aspects of care, which can have a negative impact on patients, but also on general practitioners and infectiologists. Collaboration between general practitioners and infectiologists should be based on a concerted decision, with clear allocation of tasks, taking into account the patient’s expectations. [less ▲]

Le virus de la varicelle et du zona (VZV) appartient à la famille des alpha-herpesviridae. Son cycle de réplication est similaire à celui des virus herpès simplex virus de type 1 et 2. Le VZV possède également un tropisme neuro-épidermique, une latence ganglionnaire et induit un effet cytopathique dans la cellule hôte. Le virus VZV se compose d'un ADN bicaténaire au sein de la capside virale. Le tout est enrobé d'une enveloppe contenant des glycoprotéines de sruface, qui ont un rôle important dans l'induction d'une réponse immunitaire de la part de l'hôte. L'ADN viral a été complètement séquencé. Il contient 124 884 paires de base, 71 ORF (Open Reading Frames) qui codent pour 67 protéines dont environ 33 ont été identifiées. Au stade latent, le VZV n'exprime que des protéines de latence, comme l'IE (protéine immédiate précoce) 4, 62 et 63. Lors de la réactivation virale, le VZV exprimera les gènes E et ensuite L, qui produiront respectivement des protéines E (protéines précoces), nécessaires à la synthèse de l'ADN viral et à la construction de la nucléocapside, et des protéines L (protéines tardives) consitutuant l'enveloppe virale.

We report the case of a 57-year-old patient in whom we found a pulmonary infection due to Mycobacterium malmoense. This patient had no immunodeficiency and responded quite rapidly to anti-tuberculous therapy. He was treated for 6 months by levofloxacine, myambutol, and nicotibine, followed by 3 months of clarithromycine, levofloxacine and myambutol. The patient improved clinically to become asymptomatic and the cavitary lesion shown at the CT-scan slightly decreased. The patient is still currently treated by clarithromycine and ciproxine.

Taenia solium cysticercosis is an endemic zoonosis in many developing countries. Serological tests are the most appropriate diagnostic tools to understand the transmission dynamics of the parasite, but the performances of these methods in such a setting are not known. A south Ecuadorian human population living in an endemic area was tested using three common serological tests. Because none of them is a gold standard, a Bayesian Latent Class analysis was used to estimate the test characteristics. Two definitions of a case were considered to differentiate between prevalence of current infection and prior exposure to the parasite. Differences between the performances of the same test in function of the definition of a case were observed. This study shows that test results and prior information should be interpreted carefully in a Bayesian analysis framework, particularly when the latter is based on clinical studies. [less ▲]
