Error causing a relapsing fever in Ireland



An error was found in a tick that was first collected in Ireland, causing a rare form of relapsing fever.

The bug, a strain of Borrelia, has been identified in a tick collected in Portumna, Co Galway

The Borrelia miyamotoi pathogen, first identified in 1995 in ticks from Japan, is a far cry from the bacteria, that cause Lyme disease.

The initial symptom of the disease is usually a red rash, but if left untreated, may be followed by other symptoms such as fever, muscle pain, joint swelling, and temporary paralysis of the facial muscles.

The finding is published in a study published in the Plos One Science Magazine of an Irish team of scientists, including researchers from University College Dublin and University College Cork.

They say their research shows that ticks in Ireland are infected with a variety of disease-borne Borrelia bacteria. The results also show that Borrelia-infected ticks occur in the southeast, an area that has not previously been considered significantly infected by ticks and is therefore not considered to be a risk to humans from Lyme borreliosis.

Infected Ticks

Five percent of ticks were found to carry infectious borrelia, with rates ranging from 2% in Killarney, to Co Kerry and 1

2% in Portumna. All sampling sites, including Glenveagh, Co Donegal, Glendalough, Co Wicklow, and Clifden, Co Galway, collected ticks that were infected with some form of Borrelia.

HSE estimates that there are about 100 to 200 cases of Lyme disease a year, but patient groups and some doctors say that this is too low. The new study appears to indicate that some ticks might transmit another disease that has similar symptoms to Lyme disease.

"Ticks are likely to be associated with relapsing fever borrelia, they bite humans and maybe we are patients" missing "No one knows of relapsing fever in Ireland, and the current test does not catch anyone with relapsing fever borreliosis", said Professor Jack Lambert, one of the authors of the study.

High-fever

Tick relapse Fever is characterized by a high fever that lasts for a few days, disappears for a week and then returns, although rarely, the disease occurs in the western

The disease usually disappears by itself, but severe cases are treated with antibiotics.

Health authorities say the best way to prevent infection When it comes to tick biting, it's important to take precautions in the open air, for example wearing long trousers and inserting trouser legs in socks d the use of tick repellents.
