A few reports have now established that the cat scratch disease agent Bartonella henselae is responsible for uveitis [1]. Bartonella grahamii has also been recognized as being responsible for uveitis [2]. However, the prevalence of Bartonella uveitis remains poorly known, as is the potential role of other Bartonella species. Prospective evaluation of a standardized laboratory protocol for the diagnosis of uveitis of unknown aetiology [3] showed that Bartonella species were responsible for most cases of bacterial uveitis. Prominent clinical features and laboratory diagnosis data of this large series are reported herein. This study was approved by the Ethics Committee of our institution; patients with a known aetiological diagnosis and patients with ophthalmological features pathognomonic of an aetiology, such as toxoplasmosis, were not eligible. A questionnaire was used for the collection of data, and was anonymized before the study according to French law. Informed consent for inclusion was obtained from patients and parents or legal guardians of children (i.e. age

To the Editor: The global population of bedbugs that feed on humans (Cimex lectularius, Cimex hemipterus, and Leptocimex boueti) has undergone a significant resurgence since the late 1990s. Due to increased international travel and pesticide resistance, bedbugs once thought to be native to certain geographic locations have been found in other parts of the world. Bedbugs present a socioeconomic burden because they are costly to eradicate and infestations often recur. According to the US Environmental Protection Agency, bedbugs are ‘‘a pest of significant health importance,’’ and upwards of 45 disease pathogens have been reported in bedbugs. It stands to reason to ask if bedbugs might transmit human pathogens. We performed a literature review on August 6, 2015, and searched the computerizedmedical bibliographic databases PubMed, EMBASE, CINAHL, and Web of Science with the search terms: ‘‘bedbug’’ OR ‘‘cimex lectularius.’’ A total of 1790 articles were returned, and 12 articles were suitable for inclusion (clinical and laboratory published studies [1990 to 2015] investigating bedbugs as potential vectors of infectious disease) after screening of titles, abstracts, and/or full-text articles. These articles demonstrated that although bedbugs may carry pathogens such as methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus faecium, and hepatitis B virus, and may be competent vectors of Bartonella quintana and Trypanosoma cruzi, there were no confirmed cases of human disease transmission. Previous reports suggest that, although a number of different disease pathogen species have been detected in or on bedbugs, there is a lack of definitive evidence that bedbugs transmit human pathogens. An important challenge for scientists is to determine the reason for this interesting finding.
