IgG antibodies against phospholipase A2 from Crotalus durissus terrificus: cross-reaction with venoms from Bothrops species from Argentina
Provedor de dados: 80
Autores: Rodríguez,JP; De Marzi,MC; Maruñak,S; Teibler,P; Acosta,O; Malchiodi,EL; Leiva,LC.
We examined the ability of IgG anti-crotalic PLA2 to cross-react with Bothrops spp. venoms, from snakes found in the northeast of Argentina. Immunoblotting and ELISA tests showed that IgG anti-crotalic PLA2 recognize antigens of bothropic venoms. Indirect hemolytic activity tests showed that the quantity of antibodies that neutralized 50% of Crotalus durissus terrificus venom (ED50: 2.1 mg IgG anti-crotalic PLA2/100 µg of venom) were also able to neutralize venom from other snakes in the following proportion: 34% of B. alternatus, 18% of B. diporus and 12% of B. jararacussu. Likewise, direct PLA2 activity neutralization tests showed a similar cross-neutralization pattern including 56% of B. alternatus, 29% of B. diporus and 30% of B. jararacussu. In...

General characterization of venom from the Moroccan snakes Macrovipera mauritanica and Cerastes cerastes
Provedor de dados: 80
Autores: Oukkache,N; Lalaoui,M; Ghalim,N.
Ophidian envenomation accidents constitute a serious public health problem in many countries around the globe. Over 5 million such accident cases occur each year causing more than 100,000 deaths. In Africa, more than 20,000 deaths per year are registered while 400,000 envenomation victims retain severe and permanent functional sequelae. In Morocco, snakebites are frequent and of greater severity in children. They occur mostly in rural areas. The incidence of these bites remains poorly understood and vastly underestimated. The epidemiological data are not well known due to the absence of a national registry, whereas a significant proportion of envenomations receive only traditional treatment methods in non-medical intensive care. This prompted us to...

Anti-human influenza protector antibody detected in horses as a zoonotic viruses
Provedor de dados: 62
Autores: Mancini,Dalva Assunção Portari; Mendonça,Rita Maria Zucatelli; Pinto,José Ricardo; Mori,Enio; Fernandes,Wilson Roberto.
This study aimed to investigate the incidence of the influenza virus, and its interspecies transmission cycle among horses. A comparative serological survey was performed using horse sera following challenge with both specific (equine) and non-specific (human) influenza virus strains. Bleedings of the 22 horses were performed during the years 1999 and 2000. Following treatment with kaolin (20%), added in rooster erythrocytes suspension (50%), for removal of non-specific antibodies, sera were titered against both Human and Equine Influenza virus, by the Hemagglutination Inhibition Assay(HI), recommended by WHO. The HI results of horse serological responses demonstrate cross reaction between both the specific strain, A/Eq1 (H7N7) ( 62.75%) and A/Eq2 (H3N8)...
