Sera of 30 Belgian and 10 Northern French chicken farms were tested by a Chlamydia (C.) psittaci major outer membrane protein (MOMP) based ELISA. Ninety-six percent, 93% and 90% of the Belgian broilers, broiler breeders and layers were seropositive. Ninety-one percent of the French broilers were seropositive. In addition, tissues of 5 Belgian and 5 French broiler farms were examined at slaughte...

BACKGROUND AND OBJECTIVE Chlamydophila psittaci is a lethal bacterium that causes endemic avian chlamydiosis, and respiratory psittacosis. Laboratory diagnosis of Chlamydophila psittaci is difficult by culture. This study was design to investigate the presence of Chlamydophila psittaci in collected pharyngeal swabs from asyptomatic pigeons by PCR. MATERIALS AND METHODS Pharyngeal samples from...

The aim of this study was to investigate the epidemiology of chlamydiosis in free-ranging asymptomatic and diarrhoeic sheep and goats in Egypt. Faecal swabs were examined for the presence of Chlamydiae by culture in Vero cells and chick embryos, and staining with Giménez, direct fluorescein-conjugated monoclonal antibodies, and immunoperoxidase. Specific chlamydial DNA was identified by amplifi...

In commercially raised poultry, chlamydiosis mostly seems to occur on turkey or duck farms, sometimes associated with zoonotic transmission and disease (psittacosis) in humans. However, Chlamydia infections are apparently emerging in chickens, and information on the virulence of Chlamydia in chickens is limited. Up-to-date Chlamydia psittaci genotypes B and D are most frequently found in broile...

Here, we review sexually transmitted diseases (STDs) caused by pathogenic bacteria and vaginal infections which result from an overgrowth of opportunistic bacterial microflora. First, we describe the STDs, the corresponding pathogens and the antimicrobials used for their treatment. In addition to the well-known diseases caused by single pathogens (i.e., syphilis, gonococcal infections, and chla...

There are over 2,100 pigeon fanciers in N. Ireland with approximately 150,000 racing pigeons. Historically, the sport has had little veterinary intervention. Fanciers rely heavily on various concoctions of routine treatments and antibiotics obtained principally by mail order from overseas. In recent years there have been increased losses of young birds, up to 90% in some cases. Traditionally, y...

Ovine chlamydiosis, also known as enzootic abortion of ewes (EAE) or ovine enzootic abortion (OEA), is caused by the bacterium Chlamydophila abortus. Chlamydial abortion typically occurs in the last 2–3 weeks of pregnancy with the appearance of stillborn lambs and inflamed placentas. However, infection can also result in the delivery of full-term stillborn lambs or weak lambs that do not surviv...
