Lyme disease is an infectious disease caused by a spirochete (spiral shaped bacterium) known as Borrelia burgdorferi (Bb). Lyme disease is most often spread by ticks, but can also be transmitted by fleas, mosquito's, and mites. Evidence has suggested that these insects don't actually need to bite you for you to become infected.
Lyme disease in human inhabitants in Argentina, a study was designed as a seroepidemiologic investigation of the immune response to B. burgdorferi in farm workers of Argentina with arthritis symptoms. Three out of 28 sera were positive (#1,5 and 9). Serum # 1 was positive for Immunoglobulin G at dilution 1:320, serum # 5 and # 9 both to dilution 1:160; while for Immunoglobulin M all (#1, 5 and 9) were positive at low dilution (1:40) using IF.
Treat with an oral antibiotic for two weeks. Doxycycline 100 mg bd or amoxicillin 500 mg tds. Cefuroxime 500 mg bd if both are contra-indicated and there is no history of anaphylaxis with penicillins. If unable to distinguish between cellulitis and erythema migrans, use co-amoxiclav, cefuroxime or amoxicillin with flucloxacillin. For children aged over 12, use doxycycline 100 mg bd or amoxicillin 50 mg/kg/day in divided doses (maximum 500 mg per dose).
The objective of this study was to identify the tick species parasitizing Richardson's ground squirrels (Spermophilus richardsonii) in southern Saskatchewan (Canada). Morphological examination of the adult ticks revealed the presence of three tick species, Ixodes sculptus, Ixodes kingi and Dermacentor andersoni. PCR-based single-strand conformation polymorphism (SSCP) and DNA sequence analyses of a portion of the mitochondrial (mt) 16S rRNA gene were used to determine their species identity.
