Cyanobacterial poisoning in livestock, wild mammals and birds--an overview.
نویسندگان
چکیده
Poisoning of livestock by toxic cyanobacteria was first reported in the 19th century, and throughout the 20th century cyanobacteria-related poisonings of livestock and wildlife in all continents have been described. Some mass mortality events involving unrelated fauna in prehistoric times have also been attributed to cyanotoxin poisoning; if correct, this serves as a reminder that toxic cyanobacteria blooms predate anthropogenic manipulation of the environment, though there is probably general agreement that human intervention has led to increases in the frequency and extent of cyanobacteria blooms. Many of the early reports of cyanobacteria poisoning were anecdotal and circumstantial, albeit with good descriptions of the appearance and behaviour of cyanobacteria blooms that preceded or coincided with illness and death in exposed animals. Early necropsy findings of hepatotoxicity were subsequently confirmed by experimental investigations. More recent reports supplement clinical and post-mortem findings with investigative chemistry techniques to identify cyanotoxins in stomach contents and tissue fluids.

Characterisation of Salmonella enterica serotype Typhimurium isolates from wild birds in northern England from 2005 – 2006
BACKGROUND Several studies have shown that a number of serovars of Salmonella enterica may be isolated from wild birds, and it has been suggested that wild birds may play a role in the epidemiology of human and livestock salmonellosis. However, little is known about the relationship between wild bird S. enterica strains and human- and livestock- associated strains in the United Kingdom. Given t...
متن کاملAn Overview of Sex Selection at Conception in Mammals
Although the mechanisms under which sex ratio is controlled in nature remain unknown, researchers have attempted to treat sperm in an effort to predetermine the sex of the offspring. The methods of sperm separation that have been repeatedly reported to isolate fractions rich in X- or Y-chromosome bearing sperm are serum albumin gradient swim-up and flow cytometry. However, the ability of the se...
متن کاملWild fauna as a carrier of Salmonella in Reunion Island: Impact on pig farms.
Salmonellosis is an economic burden to the livestock industry in Reunion Island. In this study, we wanted to improve our understanding of Salmonella epidemiology by studying the wild fauna of Reunion Island. We assessed Salmonella diversity in small non-flying mammals, birds and cockroaches in order to evaluate their potential role in the epidemiology of Salmonella. A total of 268 samples were ...
متن کاملContribution of the Guassa Community Eco-Lodge to the Conservation of Wild Mammals, Birds and Woody Plants in Menz-Gera Midir District, North Shewa Administrative Zone, Ethiopia
In recent decades, several eco-lodges have been established in biodiversity areas of Ethiopia. For example, plenty of eco-lodges are found in Amhara, Oromia and Southern Nation, Nationalities and People’s National Regional States. Most of the times, as eco-lodges are established from environmentally friendly, economically feasible and socially acceptable local materials, we argue that eco-lodge...
متن کاملHaematophagous bats in Brazil, their role in rabies transmission, impact on public health, livestock industry and alternatives to an indiscriminate reduction of bat population.
Haematophagous bats exist only in Latin America, from México to the Northern provinces of Argentina. They are represented by three species, Desmodus rotundus, Diphylla ecaudata and Diaemus youngii. While two species feed only on blood of wild birds, one species, D. rotundus, causes losses feeding on livestock and could be a vector for rabies virus. The cases in which humans were bitten by the b...
