Hepatic Disease with Portal Hypertension and Acute Juvenile Paracoccidioidomycosis: A Report of Two Cases and Literature Review
Paracoccidioidomycosis (PCM) is a neglected systemic mycosis endemic to Latin America caused by dimorphic fungi of the genus
Paracoccidioides
. The acute juvenile PCM is a severe type of presentation that usually affects young vulnerable patients and rarely progresses to portal hypertension. Here, two cases of liver disease and portal hypertension as complications of acute juvenile PCM are reported. Diagnosis of PCM was performed by isolation of the fungus and molecular identification of the strains provided through partial sequencing of two protein encoding genes,
arf
and
gp43
. Genotypic analysis revealed that
Paracoccidioides brasiliensis
S1 was the phylogenic species involved in both cases. Patients presented a good clinical response to amphotericin B and sulfamethoxazole–trimethoprim. These results highlight the importance of the interdisciplinary approach in patients with severe forms of PCM to avoid and treat complications, and the necessity of further investigations focusing on host-pathogen interaction in order to explain the broad clinical spectrum in PCM as well as the severity and poor outcome in some clinical cases.

Creeping slime : slime molds
\"Animal, plant, fungus--just what kind of living thing is a slime mold? How do these slimy blobs move from place to place? And how do slime molds help clean up rotting leaves and other dead stuff in backyards and forests? In this brand-new title, learn the answers to these questions and more\"-- Provided by publisher.

Disturbance, competition, and herbivory effects on ragwort Senecio jacobaea populations
The balance of forces determining the successful control of ragwort Senecio jacobaea by introduced insects was investigated in a field experiment by manipulating the time of disturbance, the level of interspecific plant competition, and the level of herbivory by the cinnabar moth Tyria jacobaeae and the ragwort flea beetle Longitarsus jacobaeae. We used a factorial design containing 0.25-m^2 plots arranged as 4 Blocks x 2 Disturbance Time (plots were tilled in Fall 1986 or Spring 1987) x 3 Plant Competition levels (vegetation other than ragwort was Removed, Clipped, or Unaltered) x 2 Cinnabar Moth levels (Exposed, Protected) x 2 Flea Beetle levels (Exposed, protected). The response of ragwort was measured as colonization, survivorship, and reproduction of the first ragwort generation, establishment of juveniles in the second generation, and changes in ragwort biomass from 1987 through 1990. We also made annual measurements from 1987 through 1990 of the allocation of space (the limiting resource in the Unaltered competition treatment) among the categories ragwort, other species, litter, and open space. Natural enemy responses were characterized by relating variation in the concentration of enemies and the concentration of ragwort among patches. We found that abundant buried seed and localized disturbances combined to activate incipient ragwort outbreaks, and that interspecific plant competition and herbivory by the ragwort flea beetle combined to inhibit the increase and spread of incipient outbreaks. Time of disturbance had little effect on the outcome of biological control. Under conditions in the Removed and Clipped treatments (where there was sufficient open space for germination and establishment), reduction in seed production in the first generation caused by cinnabar moth larvae led to a reduction in plant numbers in the second generation, but caused only a weak effect on ragwort cover and no detectable effect on ragwort biomass over the longer term from 1986 through 1990. At the spatial scale examined, inhibition by the ragwort flea beetle and plant competition took the extreme form of elimination of all ragwort individuals except the pool of seed buried in the soil. Our findings lead us to (1) reject the view that successful biological control leads to a stable pest-enemy equilibrium on a local spatial scale, (2) strongly endorse @'search and destroy@' and weakly endorse @'complementary enemies@' strategies suggested by Murdoch et al. (1985) as ways to improve control, and (3) emphasize resource limitation in the pest at low density as a key feature distinguishing biological control of weeds from biological control of insects.

Fungi grow
\"Fungi are all around us. They root and fruit and twist and twine. The mycelium roots spread below ground while the mushroom fruits pop above the earth. Some are edible, and some are poisonous. Some help keep forests communicate, others recycle decaying matter. But all across the world, fungi are growing. Discover when, how, where, and why in this poetic and illuminating nonfiction picture book\"-- Provided by publisher.

Little Tree and the wood wide web
\"Little Tree is very small on the dark forest floor. She is terribly lonely and she can't reach any light or water. Her worried feeling sinks down to the tips of her roots. But little does she know her roots are connected to a network of fungus that connects every single tree in the forest. The network sends her message all over the forest! \"Little Tree needs help!\" But who will listen?\"-- Provided by publisher.
