Interactions between environment, wild animals and human leptospirosis

Leptospirosis, a worldwide distributed zoononis caused by bacteria of the genus Leptospira (antigenically classified into serovars), may be direct or indirectly transmitted through infected urine or environment. Several domestic and wild animals are leptospirosis reservoirs. The disease presents occupational character since it is widely reported in professionals that work in humid environments ...

Safety Assessment of cryIAc for human, animals and environment

Risk assessment of a transgene is one of the key steps in genetic transformation. Hence, in order to use cryIAc gene for production of transgenic plants, a library and in-silico research was performed to confirm safety of the gene for human comsumption, animal feed and environment. In the first step, the molecular mechanism of action of the CryIAc protein and its specific receptors in the midgu...

Control of leptospirosis in man and animals.

Occurrence of enterococci in animals in a wild environment.

Enterococci were obtained from the feces of 71% of 216 mammals, 86% of 70 reptiles, and 32% of 22 birds sampled in a truly wild environment, the Great Smoky Mountains National Park. Patterns of food dependence and also of species dependence were observed. Among the lower classes of the primarily herbivorous mammals, the enterococci occurred sporadically; however, of the six species of Sciuridae...

Transmission of Neospora caninum between wild and domestic animals.

To determine whether deer can transmit Neospora caninum, brains of naturally infected white-tailed deer (Odocoileus virginianus) were fed to 4 dogs; 2 of these dogs shed oocysts. Oocysts from 1 of the dogs were tested by polymerase chain reaction and found to be positive for N. caninum and negative for Hammondia heydorni. The internal transcribed spacer 1 sequence of the new strain (designated ...
