1/4. rhipicephalus sanguineus (acari: ixodidae), the brown dog tick, parasitizing humans in brazil.

    The objective of this paper is to describe four cases of human parasitism by rhipicephalus sanguineus (Latrielle) in brazil. During an investigation regarding the species of ectoparasites of domestic dogs from the metropolitan region of Recife, Pernambuco state, four dog owners were found to be parasitized by ticks. The ticks were collected from these individuals and their dogs. All the ticks were identified as rhipicephalus sanguineus . These are, to our knowledge, the first four cases of human parasitism by this tick species in brazil. The possible implications of this finding are discussed here.

2/4. Complete heart block in a dog seropositive for borrelia burgdorferi. Similarity to human Lyme carditis.

    lyme disease has been recognized in humans since 1975 when it was associated with an outbreak of oligoarthritis in children in Lyme, connecticut. erythema chronicum migrans (ECM) is a clinical marker for the human disease, which usually appears within 3 to 32 days after an infected tick bite. lyme disease is caused by spirochete, borrelia burgdorferi, which is vectored by the hard ticks ixodes dammini or ixodes pacificus in the united states. In humans, lyme disease has been found to cause a variety of clinical syndromes including cardiopathy, neuropathy, dermatopathy, and arthropathy. Human Lyme carditis is characterized by varying degrees of atrioventricular (AV) heart block that usually resolve regardless of therapy. lyme disease has been reported in the dog as an arthropathy. This article reports a case of complete heart block and myocarditis in a dog with a positive titer for B burgdorferi, in which clinical and pathologic findings were similar to those seen in human Lyme myocarditis.

3/4. A case of tick-borne encephalitis in japan and isolation of the the virus.

    A case of tick-borne encephalitis (TBE) has not been reported for many years in japan, although a serological survey of sera from domestic animals suggested the presence of TBE foci in Hokkaido, the northern island of japan. Studies were conducted to prove the presence of an endemic focus of TBE virus in japan by means of serology and virus isolation. In October 1993 in Hokkaido, a severe case of encephalitis in a dairy farmer's wife was diagnosed as TBE. Serological examination of paired serum specimens showed a rise in the neutralization antibody titer to Russian spring summer encephalitis virus. A seroepizootiological survey of dogs showed that the TBE-related virus was prevalent in the area. Three virus isolates were obtained from the blood of sentinel dogs, and antigenic analysis grouped the isolates into TBE-related viruses. sequence analysis of the envelope protein gene identified one of the isolates as being of the same subtype as the Russian spring summer encephalitis (Far Eastern TBE) virus. The results provide evidence that TBE is endemic in a certain area of japan.

4/4. epidemiology of tick-borne encephalitis in japan.

    A tick-borne encephalitis (TBE) patient has not been reported for many years in japan although a serological survey of domestic animal sera suggested the presence of TBE foci in Hokkaido, the northern island of japan. In October 1993 in Hokkaido, a severe encephalitis case in a farm wife was diagnosed as tick-borne encephalitis. Serological examination of paired sera showed a rise of neutralization (NT) antibody titer to Russian spring summer encephalitis virus. A sero-epizootiological survey of dogs showed that the TBE-related virus was prevalent in the area. Three virus isolates were obtained from the blood of sentinel dogs and the antigenic analysis grouped the isolates into TBE-related viruses. sequence analysis of envelope protein gene identified one of the isolates as the same subtype as Russian spring summer encephalitis (Far-Eastern TBE) virus. The results provide the evidence that TBE is endemic in a certain area of japan.
