[Immunity and tubular dysfunction in case of systemic disease].

The immune renal tubular diseases are known since five decades, but their prevalence remains to be defined. They are caused by humoral and cellular effectors of innate and adaptative immunities on several targets of the renal tubule: protein channels, co or counter transporters, luminal or cytosolic enzymes, tight junctions. Genetic or epigenetic variations are also involved.

Pharyngeal Carriage of Beta-Haemolytic Species and Seroprevalence of Anti-Streptococcal Antibodies in Children in Bouaké, Côte d'Ivoire.

The pharynx of the child may serve as a reservoir of pathogenic bacteria, including beta-haemolytic group A streptococci (GAS), which can give rise to upper airway infections and post-streptococcal diseases. The objective of this study was to determine the prevalence of beta-haemolytic spp. in pharyngeal samples stemming from children aged 3-14 years in Bouaké, central Côte d'Ivoire.

[The standardization of diagnostic of hepatitis E.].

The study was carried out to develop approaches to standardization of laboratory diagnostic of hepatitis E. The three stages of standardization are establishment of analytical sensitivity of molecular test for detection of RNA of virus of hepatitis E; establishment of analytical sensitivity in International Units of enzyme-linked immunosorbent assay testing widely applied in Russia for detection of anti-virus of hepatitis E; And development of national reference material - standard anti-virus of hepatitis E IgG validated relatively to International standard. The results of study permitted to develop tools for standardizing of laboratory diagnostic of hepatitis E and epidemiological control of the given function - molecular test for detecting RNA of virus of hepatitis E with sensitivity within range of 1250250 IU/ml, data concerning analytical sensitivity of commercial enzyme-linked immunosorbent assay testing for detecting anti-virus of hepatitis E (0.

Towards an optimal design of target for tsetse control: comparisons of novel targets for the control of Palpalis group tsetse in West Africa.

Background: Tsetse flies of the Palpalis group are the main vectors of sleeping sickness in Africa. Insecticide impregnated targets are one of the most effective tools for control. However, the cost of these devices still represents a constraint to their wider use.

How do tsetse recognise their hosts? The role of shape in the responses of tsetse (Glossina fuscipes and G. palpalis) to artificial hosts.

Palpalis-group tsetse, particularly the subspecies of Glossina palpalis and G. fuscipes, are the most important transmitters of human African trypanomiasis (HAT), transmitting >95% of cases. Traps and insecticide-treated targets are used to control tsetse but more cost-effective baits might be developed through a better understanding of the fly's host-seeking behaviour.

Long-term research sites as refugia for threatened and over-harvested species.

The presence of researchers, ecotourists or rangers inside protected areas is generally assumed to provide a protective effect for wildlife populations, mainly by reducing poaching pressure. However, this assumption has rarely been empirically tested. Here, we evaluate and quantify the conservation benefits of the presence of a long-term research area in Taï National Park, Côte d'Ivoire.

[Segmental arterial mediolysis and renovascular hypertension].

Segmental arterial mediolysis (SAM) is a rare nonarteriosclerotic, noninflammatory vascular disease of unknown origin that causes vascular occlusion or massive life-threatening intraabdominal hemorrhages. SAM is an acute disease. The initial injurious phase consist in mediolysis, then evolves in chronic vascular lesions.

Prospects for the development of odour baits to control the tsetse flies Glossina tachinoides and G. palpalis s.l.

Field studies were done of the responses of Glossina palpalis palpalis in Côte d'Ivoire, and G. p. gambiensis and G.

Recurrent anemia in kidney transplant recipients with parvovirus B19 infection.

Parvovirus B19 (PV B19) infection is known to cause acute anemia in solid organ transplant recipients. Intravenous immunoglobulin combined with reduction of immunosuppression may be of benefit to clear the infection. However, PV B19-associated anemia can be recurrent.
