In four patients with an adult chlamydial ophthalmia small, marginal corneal abscesses were detected. These corneal abscesses were associated with unilateral papillary and follicular conjunctivitis and punctate keratitis. In these patients no bacteria was isolated from the abscesses, but Chlamydia trachomatis was isolated from materials collected from the abscesses and from the conjunctival swabbings. In addition all patients had microbiologically proved concomitant chlamydial genital infections. The clinical signs resolved after topical treatment with rifampicin or tetracycline eye ointment for six weeks or systemic treatment with tetracycline for two weeks. Because of concomitant chlamydial genital infection it is advisable to treat patients with adult chlamydial ophthalmia with systemic tetracycline and to refer these patients and their consorts for investigation and treatment of their genital infection.

Cryptococcus albidus is a saprophytic, encapsulated yeast usually found in air, both outdoor and indoor, and sometimes on human skin. It is not usually considered to be a primary pathogen. Most cryptococcal infections of humans and animals are caused by Cryptococcus neoformans. Several cases of C. albidus infection have been reported in humans over the past 20 years. In the veterinary literature, 2 equine cases have been described: genital infection and mycotic keratitis. The present report is the first documented case of C. albidus systemic infection in a dog. Veterinarians and diagnosticians should be aware that C. albidus may be a potential canine pathogen.

An 18 year old man was seen at a Sexually Transmitted Infections (STIs) clinic for counselling and treatment of Chlamydia trachomatis genital infection which had been diagnosed during a screening survey of high school students. For two months he had reported conjunctival hyperaemia, increased tearing, itching, and mucopurulent secretions, predominantly on the left eye. His ophthalmologist had made a diagnosis of follicular conjunctivitis and lower superficial punctate keratitis (left eye more than right eye), irresponsive to topical treatment. Chlamydial conjunctivitis was suspected and confirmed by a positive nucleic acid amplification test (NAAT) performed on conjunctival scraping. The patient was treated with azithromycin 1 g single dose orally and tetracycline/betamethasone eye ointment for one month. A complete resolution of symptoms was observed three months after aetiological treatment. This case highlights the need to include C. trachomatis infection in the differential diagnosis of acute or chronic follicular conjunctivitis among sexually active young individuals.

Antibiotic-resistant gonorrhea is now a reality, as well as the consequences of untreatable infections. Gonococcal eye infections result in blindness if not properly treated; they accounted for the vast majority of infections in children in homes for the blind in the pre-antibiotic era. Neisseria gonorrhoeae infects the eyes of infants born to mothers with gonorrhea and can also infect the eyes of adults. Changes in sexual practices may account for the rise in adult gonococcal eye infections, although some cases seem to have occurred with no associated genital infection. As gonorrhea becomes increasingly difficult to treat, the consequences for the treatment of gonococcal blindness must be considered as well. Monocaprin was shown to be effective in rapidly killing N. gonorrhoeae, and is non-irritating in ocular models. Repeated passage in sub-lethal monocaprin induces neither resistance in gonococci nor genomic mutations that are suggestive of resistance. Here, we show that 1 mM monocaprin kills 100% of N. gonorrhoeae in 2 min, and is equally effective against N. meningitidis, a rare cause of ophthalmia neonatorum that is potentially lethal. Monocaprin at 1 mM also completely kills Staphylococcus aureus after 60 min, and 25 mM kills 80% of Pseudomonas aeruginosa after 360 min. Previously, 1 mM monocaprin was shown to eliminate Chlamydia trachomatis in 5 min. Monocaprin is, therefore, a promising active ingredient in the treatment and prophylaxis of keratitis, especially considering the growing threat of gonococcal blindness due to antimicrobial resistance.
