BACKGROUND Latency is a key feature of the animal pathogen Chlamydia abortus, where infection remains inapparent in the non-pregnant animal and only becomes evident during a subsequent pregnancy. Often the first sign that an animal is infected is abortion occurring late in gestation. Despite this, little is understood of the underlying mechanisms that control latency or the recrudescence of inf...
INTRODUCTION In order to investigate the role of roe deer in the maintenance and transmission of infectious animal and human diseases in Flanders, we conducted a serologic screening in 12 hunting areas. MATERIALS AND METHODS Roe deer sera collected between 2008 and 2013 (n=190) were examined for antibodies against 13 infectious agents, using indirect enzyme-linked immunosorbent assay, virus n...
This study aimed to investigate the prevalence rate of brucellosis, leptospirosis, and chlamydiosis in offspring free-living sea lions ( Zalophus californianus ) Mexican Gulf California. The work was carried out across six islands where reproduction takes place. Sixty-one blood samples were collected from seemingly healthy eight weeks old. For diagnosis, serum obtained by venae cavae puncture. ...
Infection with chlamydial bacteria, specifically Chlamydophila pecorum, C. abortus, and C. psittaci, is common in cattle. Infection can cause different diseases of which suband infertility are the most often observed clinical manifestations. While bulls are usually carriers of chlamydia bearing the risk of being vectors for an infection of females, either through natural mating or artificial in...
Chlamydiaceae are Gram-negative obligate intracellular bacteria. They are responsible for a broad range of diseases in animals and humans. In pigs, Chlamydia suis, Chlamydia abortus, Chlamydia pecorum and Chlamydia psittaci have been isolated. Chlamydiaceae infections in pigs are associated with different pathologies such as conjunctivitis, pneumonia, pericarditis, polyarthritis, polyserositis,...
The resolution of Chlamydophila abortus (Chlamydia psittaci serotype 1) infection is dependent on gamma interferon and CD8(+) T cells, and classically, B cells have been considered to play a minimal role in host defense. The role of B cells in the immune response was studied by using a model of infection in mice with genetically modified immunoglobulin M transmembrane domains ( micro MT). In th...
Enzootic abortion of ewes (EAE) due to infection with the obligate intracellular pathogen Chlamydia (C.) abortus is an important zoonosis leading to considerable economic loss to agriculture worldwide. The pathogen can be transmitted to humans and may lead to serious infection in pregnant women. Knowledge about epidemiology, clinical course and transmission to humans is hampered by the lack of ...
Bacterial, protozoal and viral diseases are major causes of abortion in sheep goats. These agents cause significant economic losses, many considered concern for public health (zoonotic pathogens) and/or the international trade livestock, such as those causing notifiable to World Organization Animal Health (OIE). In South America, information about their occurrence, prevalence impact is scarce. ...
