Risk of Lyme disease development after a tick bite

Abstract

In prevention of Lyme disease it is important to urgent remove a tick, to use a correct procedure of removing and to remove the whole tick without any remnants.

Seroprevalence of <italic>Borrelia burgdorferi</italic> in occupationally exposed persons in the Belgrade area, Serbia

“…The ticks were professionally removed, and none of the soldiers in our study gave accurate information on how long the ticks remained in the skin. The results of Mladenovic et al (2010) showed that subjects in which ticks remained in the skin for less than 24 hours did not develop EM, indicating that removal of a tick within this period may have a protective effect. However, if a tick remains attached longer, the risk of developing B. burgdorferi infection increases proportionally ( Mladenovic et al , 2010 ).…”

However, if a tick remains attached longer, the risk of developing B. burgdorferi infection increases proportionally ( Mladenovic et al , 2010 ). Some authors found though that migration of spirochetes in ticks and their transmission to susceptible hosts was recorded in less than 24 hours after a tick bite ( Kahl et al , 1998 ; Crippa et al , 2002 ).…”

“…He removed the tick himself and did not know for how long the tick was in the skin before it was removed. It should be noted that the risk of developing an early phase of LD is statistically significantly higher in patients who removed the tick unprofessionally compared to those who did it in a medical institution ( Mladenovic et al , 2010 ). As has been mentioned, the LD seroprevalence in this group was 11.76%.…”

“…Serbian as well as many foreign authors recommend prophylactic use of antibiotics after tick bite in people with a higher risk of LD, e.g. if a tick was in the skin for over 24 hours, or if the time is unknown, or if a tick was removed unprofessionally or incompletely ( Mladenovic et al , 2010 ; Patey, 2007 ).…”

Identificação do agente etiológico da Doença de Lyme-símile brasileira (Síndrome Baggio-Yoshinari)

“…No sul dos EUA existe uma apresentação conhecida como doença de Masters ou STARI (Southern Tick Associated Rash Illness) (Masters et al, 1998), caracterizada pelo desenvolvimento de "rash" semelhante ao EM, na ausência de sintomatologia sistêmica, sendo transmitida pelo Amblyomma americanum e causada pela B. lonestari, a qual é incultivável em meio BSK e, recentemente tornou-se cultivável em células de carrapatos (Varela et al, 2004 (Spach et al, 1993;LoGiudice et al, 2003;Mladenović et al, 2010;Hamer et al, 2010).…”
