Lyme borreliosis is a zoonosis characterized by great clinical polymorphism.
We report 2 cases in patients who presented ocular manifestations: one
anterior uveitis in an adult, which resolved under treatment, and one
posterior uveitis in a child, whose initial ophthalmologic examination
already showed retinal fibrous scars including the macular area. Lyme
disease is on the long list of causes that must be discussed in cases of
uveitis. The diagnosis is based on a series of epidemiological, clinical,
and biological arguments with Western Blot serological profile analysis.
Treatment is based especially on intravenous antibiotics. Copyright (c) 2010

Background Babesiosis, a zoonosis caused by the protozoan Babesia microti, is usually not treated when the symptoms are mild, because the parasitemia appears to be transient. However, the microscopical methods used to diagnose this infection are insensitive, and few infected people have been followed longitudinally. We compared the duration of parasitemia in people who had received specific antibabesial therapy with that in silently infected people who had not received specific therapy.

Methods Forty-six babesia-infected subjects were identified from 1991 through 1996 in a prospective, community-based study designed to detect episodes of illness and of seroconversion among the residents of southeastern Connecticut and Block Island, Rhode Island. Subjects with acute babesial illness were monitored every 3 months for up to 27 months by means of thin blood smears, Bab. microti polymerase-chain-reaction assays, serologic tests, and questionnaires

Excerpt:

Human ehrlichiosis and anaplasmosis are acute febrile tick-borne
diseases caused by various members of the genera Ehrlichia and
Anaplasma (Anaplasmataceae).
Human monocytotropic ehrlichiosis has become one of the most
prevalent life-threatening tick-borne disease in the United
States. Ehrlichiosis and anaplasmosis are becoming more
frequently diagnosed as the cause of human infections, as animal
reservoirs and tick vectors have increased in number and humans
have inhabited areas where reservoir and tick populations are
high.
Ehrlichia chaffeensis, the etiologic agent of human
monocytotropic ehrlichiosis (HME), is an emerging zoonosis that
causes clinical manifestations ranging from a mild febrile
illness to a fulminant disease characterized by multiorgan system
failure. Anaplasma phagocytophilum causes human granulocytotropic
anaplasmosis (HGA), previously known as human granulocytotropic
ehrlichiosis. This article reviews recent advances in the
understanding of ehrlichial diseases related to microbiology,
epidemiology, diagnosis, pathogenesis, immunity, and treatment of
the 2 prevalent tick-borne diseases found in the United States,
HME and HGA.

Summary Cat scratch disease is the most common zoonotic infection
caused by Bartonella bacteria. Among the many mammals infected
with Bartonella spp., cats represent a large reservoir for human
infection, as they are the main reservoir for Bartonella
henselae, Bartonella clarridgeiae and Bartonella koehlerae.
Bartonella spp. are vector-borne bacteria, and transmission of B.
henselae by cat fleas occurs mainly through infected flea faeces,
although new potential vectors (ticks and biting flies) have been
identified. Dogs are also infected with various Bartonella
species and share with humans many of the clinical signs induced
by these infections. Although the role of dogs as source of human
infection is not yet clearly established, they represent
epidemiological sentinels for human exposure. Present knowledge
on the aetiology, clinical features and epidemiological
characteristics of bartonellosis is presented.
