ABSTRACT Closterovirus-like particles associated with mealybug wilt of pineapple were acquired and transmitted by the pink pineapple mealybug, Dysmicoccus brevipes, and the gray pineapple mealybug, D. neobrevipes. Mealybugs acquired pineapple mealybug wilt-associated virus (PMWaV) from infected pineapple plants or detached leaves. The virus was detected in plants by tissue blot immunoassay and ...

In this study, we determined that some micromorphological structures of plants have geometric models and mathematical formulas. There are specialized in perform tasks such as making usable, storing transmitting the products formed a result metabolic activities. These take different shapes depending on complexity their functions. enable them to duties most efficient way. As examinations under mi...

Most congenital transmissions of Trypanosoma cruzi are not detected. As the levels of mediators regulating the immune response might be different in the absence or in the presence of transmission, we explored the levels of tumor necrosis factor (TNF) and soluble TNF receptors TNF-R1 and -R2 in T. cruzi-infected pregnant women and the neonates. We previously found that the circulating levels of ...
