Mangrove soils have unique properties, able to transform and sequester chemical compounds of biogeochemical and ecological importance, including heavy metals. The degeneration of mangrove soils shows the risk of releasing these metals to the environment. We search for improve the knowledge about how disturbance affects the metal fixation and microbial of mangrove soils. This study characterized a mangrove soil along the Graciosa River estuary (Bahia, Brazil), according to selected physical, chemical and microbiological properties. In 2002, soil was collected from an anthropic and from an adjacent natural site. Both sites were re-sampled in 2007, after a vegetal regeneration on the anthropic site. Significant differences between the natural and anthropic surface layers were observed for chemical and physical soil properties. In particular, heavy metals (Co, Cr, Cu, Zn, Ni, Mn and Fe) showed significant differences with depth and lower concentrations were found in the anthropic site, exception to Cd (moderately high). Between 2002 and 2007, the disturbed site showed a decrease for all observed metals, except for Ni. The data also suggest that microbial populations may be favored in the layers of the soil profile most influenced by high and low tides, C1 (0-20 cm) and C5 (99-125 cm). |

A survey was conducted to identify reservoirs for urban leptospirosis in the city of Salvador, Brazil. Sampling protocols were performed in the vicinity of households of severe leptospirosis cases identified during active hospital-based surveillance. Among a total of 142 captured Rattus norvegicus (Norwegian brown rat), 80.3% had a positive culture isolate from urine or kidney specimens and 68.1% had a positive serum sample by microscopic agglutination test (MAT) titre of ?1:100. Monoclonal antibody-based typing of isolates identified that the agent carried by rats was Leptospira interrogans serovar Copenhageni, which was the same serovar isolated from patients during hospital-based surveillance. Leptospira spp. were not isolated from 8 captured Didelphis marsupialis (Opossum), while 5/7 had a positive MAT titre against a saprophytic serogroup. R. rattus were not captured during the survey. The study findings indicate that the brown rat is a major rodent reservoir for leptospirosis in this urban setting. Furthermore, the high carriage rates of L. interrogans serovar Copenhageni in captured rats suggest that there is a significant degree of environmental contamination with this agent in the household environment of high risk areas, which in turn is a cause of transmission during urban epidemics. |
