Perinatal transmission of the agent of human granulocytic ehrlichiosis
Article Abstract:
The case of a pregnant 35-year-old woman illustrates that the organism that causes human granulocytic ehrlichiosis may be transmitted during childbirth. This infection is transmitted by ticks and causes a feverish illness. The woman had been feverish before labor and had seen ticks on her the week before. She became ill the day after delivery and blood samples taken two days later revealed the presence of the Ehrlichia organism. The newborn infant became ill on her ninth day of life and blood samples revealed that she was also infected with Ehrlichia.

Culture-confirmed infection and reinfection with Borrelia burgdorferi
Article Abstract:
A woman was shown to have been reinfected with Borrelia burgdorferi, the bacterium that causes Lyme disease, 3 years after her initial infection. The woman, who was 60 years old at the time of the first infection, returned after 3 years, shortly after having had a high temperature and a headache. Biopsy samples were cultured and showed the bacterium to be a different strain from the first. This strongly suggests that reinfection is possible and that an episode of Lyme disease does not confer any immunity to future infections.

Antibody levels to recombinant tick calreticulin increase in humans after exposure to Ixodes scapularis (Say) and are correlated with tick engorgement indices
Article Abstract:
Antibody levels in saliva may activate an immune response to tick bites, the precursor of Lyme disease. Researchers examined the saliva of 95 people with a recent tick bite. The antibody levels remained high over time and correlated with the tick engorgement indices. Logistic regression modelling revealed that engorged tick bites were a risk factor for anti-rTC antibody seropositivity.
