“…H. cinaedi has been isolated from a wide variety of patients 5 , but is most frequently associated with homosexual men both with and without HIV infection. It typically presents with gastrointestinal symptoms 6,7 and bacteraemia 5 , and has recently been reported in the US as a cause of cellulitis 5 , although it has also been isolated from asymptomatic gay men 6,7 . H. cinaedi is notoriously dif® cult to isolate and culture 5,7± 10 and is therefore probably frequently missed as a causative pathogen of cellulitis.…”

“…Among the homosexual or bisexual male population, Campylobacter spp. has been isolated in 3.6% of asymptomatic persons, in 19.7% of patients with gastrointestinal symptoms, and in 8.7% of patients with AIDS with or without diarrhea [14]. From 1996 to 2000, studies from Canada, the United States, Europe, and Australia reported an increase in the number of MSM engaging in risky sexual behaviors and in the number of MSM contracting STDs [15].…”

From December 1999 to November 2001, a cluster of multidrug-resistant Campylobacter jejuni subsp. jejuni enterocolitis was suspected within the male population of Montreal. Nine men, aged 26-40 years, presented with an erythromycin- and ciprofloxacin-resistant, tetracycline-susceptible C. jejuni enterocolitis. In March 1998 and February 2000, 2 additional men, aged 23 and 27 years, were infected with an erythromycin-resistant, ciprofloxacin and tetracycline-susceptible C. jejuni. All isolates were identical according to pulsed-field gel electrophoresis and flagellin typing. Epidemiological data suggested a sexually transmitted enteric infection; all patients infected with the locally acquired epidemic strain were men, the 8 patients for whom sexual orientation data were available identified themselves as men who have sex with men (MSM), and 3 of the patients had had a sexually transmitted Shigella sonnei infection during a proven outbreak among MSM. Eight patients, 6 of whom were identified as MSM, resided in a predominantly homosexual district of Montreal or its surrounding neighborhoods. The emergence of multidrug-resistant C. jejuni justifies routine susceptibility-testing of these bacteria. MSM should be educated about the prevention of sexually transmitted enteric pathogens.

“…Early reports described its association with proctocolitis, but H. cinaedi may also cause bacteremia (3,17,19,22,26,35), cellulitis (2, 13), and septic arthritis (2,14). Infection is sometimes asymptomatic (15,16,25) and can occur in other immunocompromised patients (13) or occasionally in normal hosts (14,30,32).Like Campylobacter infections, enterohepatic Helicobacter infections are believed to be acquired by humans from pets or farm animals (28). In one series of 23 patients with H. cinaedi infections (13), the most frequent exposures of interest were contact with animals (n ϭ 9) or untreated surface water (n ϭ 3), However, little is known about the animal reservoir(s) for H. cinaedi.…”

Captive Rhesus Monkeys ( Macaca mulatta ) Are Commonly Infected with Helicobacter cinaedi

et al. 2002

Helicobacter cinaedi may cause proctocolitis or bacteremia in homosexual men infected with human immunodeficiency virus or occasionally in other immunocompromised hosts. There are scattered reports of H. cinaedi isolated from a variety of animal hosts, but to date only hamsters have been found to be a common natural reservoir. Microaerophillic cultures of feces from 5 of 16 asymptomatic rhesus monkeys (Macaca mulatta) (31%) were positive for a curved gram-negative rod. A polyphasic taxonomic approach was used to identify the organism as H. cinaedi. These results show that H. cinaedi frequently colonizes asymptomatic captive rhesus monkeys, which may serve as another potential reservoir for human infection.A heterogeneous group of Campylobacter-like organisms was first isolated by culturing of rectal swabs from homosexual men, many of whom had symptoms of proctitis and colitis (5, 25). DNA-DNA hybridization suggested that one group of these organisms (CLO-1) comprised a single species (31), which was designated Campylobacter cinaedi (Latin, of a homosexual) and later changed to Helicobacter cinaedi based on further genotypic characterization (33). H. cinaedi is most commonly isolated from homosexual men infected with human immunodeficiency virus. Early reports described its association with proctocolitis, but H. cinaedi may also cause bacteremia (3,17,19,22,26,35), cellulitis (2, 13), and septic arthritis (2,14). Infection is sometimes asymptomatic (15,16,25) and can occur in other immunocompromised patients (13) or occasionally in normal hosts (14,30,32).Like Campylobacter infections, enterohepatic Helicobacter infections are believed to be acquired by humans from pets or farm animals (28). In one series of 23 patients with H. cinaedi infections (13), the most frequent exposures of interest were contact with animals (n ϭ 9) or untreated surface water (n ϭ 3), However, little is known about the animal reservoir(s) for H. cinaedi. There are scattered reports of H. cinaedi isolates from various animal hosts, including dogs, cats, foxes, and a rat (12, 34). However, only hamsters have been found to be a common natural reservoir. H. cinaedi was isolated from 54 (75%) of 72 healthy hamsters obtained on multiple occasions from two commercial breeders (9). Interestingly, H. cinaedi septicemia and meningitis have been reported in a neonate whose mother cared for pet hamsters (20). In the course of our studies on the rhesus macaque model of Helicobacter pylori, we unexpectedly identified H. cinaedi in a fecal culture. Subsequent cultures showed that H. cinaedi commonly infects captive rhesus monkeys, which may serve as another animal reservoir for human infection. MATERIALS AND METHODS Animals.Sixteen male and female rhesus macaques (Macaca mulatta) between 2 and 5 years old were studied. All animals were individually housed indoors at the California Regional Primate Research Center. One animal had intermittent clinical evidence of colitis (liquid stools observed by an animal technician during the morning health report), ...
