Abstract
A cow dairy (n = 2000) in close proximity to a sheep flock had third-trimester abortions and fatalities in cows and calves over a 14-month period. Eighteen of 33 aborted fetuses (55%) had multifocal random suppurative or mononuclear meningoencephalitis with vasculitis. Seventeen of these affected fetuses had intracytoplasmic bacteria in endothelial cells, and 1 fetus with pericarditis had similar bacteria within mesothelial cells or macrophages. Immunohistochemistry for Chlamydia spp. or polymerase chain reaction (PCR) for Chlamydia pecorum or both, performed on brain or pooled tissue, were positive in all 14 tested fetuses that had meningoencephalitis and in 4/4 calves and in 3/4 tested cows that had meningoencephalitis and thrombotic vasculitis. In 1 calf and 11/11 fetuses, C. pecorum PCR amplicon sequences were 100% homologous to published C. pecorum sequences. Enzootic chlamydiosis due to C. pecorum was the identified cause of the late term abortions and the vasculitis and meningoencephalitis in fetuses, calves, and cows. C. pecorum, an uncommon bovine abortogenic agent, is a differential diagnosis in late-term aborted fetuses with meningoencephalitis, vasculitis, and polyserositis.

Abstract
Chlamydia pecorum is an obligate intracellular pathogen with a wide host range including livestock such as sheep, cattle, goats, and pigs as well as wildlife species such as koalas. Chlamydial polyarthritis is an economically important disease resulting in swollen joints, lameness, stiffness, and weight loss in young sheep. In the present study, tissues from sheep experimentally or naturally infected with Chlamydia pecorum were assessed by histopathology and immunohistochemistry. Carpal, hock, and stifle joints as well as spleen, liver, kidney, lymph nodes, lung, and brain of 35 sheep from different inoculation groups were available. Two different C. pecorum strains (IPA and E58), different routes of administration (intraarticular or intravenous), UVA-irradiated IPA strain, and corresponding noninfected control groups were investigated. Similar investigations on tissues from 5 naturally infected sheep were performed. The most obvious inflammatory lesions were observed in synovial tissues and, notably, in the renal pelvis from the experimentally infected group and naturally infected animals. This resulted in chronic or chronic-active arthritis and pyelitis. Intralesional chlamydial inclusions could be demonstrated by immunohistochemistry in both tissues. Immunohistochemical evaluation of the presence and distribution of macrophages, T and B cells in synovial tissues revealed macrophages as the most prevalent inflammatory cell population. Previous observations indicated that C. pecorum isolates can infect circulating monocytes. Together with the finding of the histological lesions in synovial tissues and internal organs alongside the presence of C. pecorum DNA, these observations suggest chlamydial arthritis in lambs is the result of hematogeneous spread of C. pecorum.

Abstract
Serological tests of 35 patients suffering from inflammatory bowel disease were compared to those of 35 healthy controls. The tests were performed using the indirect immunoperoxidase assay. Ninety-three per cent of 15 patients with Crohn's disease had IgG antibodies against Chlamydia, compared to 26% in the control group. In the 20 patients with ulcerative colitis, 45% had IgG antibodies against Chlamydia, compared to 10% in the control group. High serum titres of IgG antibodies were found in most of the patients with inflammatory bowel disease, mainly with Crohn's disease, while weak reactions appeared in most of the controls in which antibodies were detected. These results suggest a high incidence of Chlamydia infection in the studied patients with inflammatory bowel disease, especially in those with Crohn's disease. The possible association between Chlamydia trachomatis and inflammatory bowel disease is discussed.

Abstract
BACKGROUND Over the last several years, we have demonstrated that intestinal lymphangitis and lymphatic obstruction are fundamental lesions in Crohn's disease, for which no therapy is currently available. There is an infectious enteritis of young pigs that offers an opportunity to understand how the lymphangitis of CD may have been initiated. The pathology of chlamydial enteritis was described earlier, from 1987 to 2009. MATERIALS AND METHODS Tissue blocks and hematoxylin and eosin-stained slides from Chlamydia suis-inoculated young pigs were provided by D. Rogers and F. Guscetti. Experimental animals, gnotobiotic and conventional, had been autopsied 4, 7, and 10 days postinoculation. Serial sections of intestine were immunostained with a Chlamydia trachomatis antibody, which cross-reacted with C. suis antigen, and compared with hematoxylin and eosin preparations. RESULTS Immunohistochemistry revealed antigen in villous epithelial cells of jejunum and ileum and in the endothelium of lacteals and lymphatics by day 4. This was accompanied by lymphatic endothelial necrosis, lymphangitis, and inflammatory lymphatic obstruction, through several layers of the affected intestinal segments, days 4 through 10. CONCLUSIONS Although the original authors documented lesions to define the porcine disease, here the author characterizes the lymphangitis as a model for understanding Crohn's disease and suggests a chlamydial origin for the latter.

Abstract
There is a growing recognition that infections of livestock by the obligate intracellular bacterium, Chlamydia pecorum, are more widespread than was previously thought. A range of diseases have been associated with this pathogen, with the most important manifestations including infectious arthritis, infertility, enteritis, reduced growth rates, mastitis, and pneumonia. C. pecorum infections have also been associated with sub-clinical disease, highlighting our lack of knowledge about its true economic impact on livestock producers. Diagnosis of C. pecorum infection is based on clinical findings, serology and histopathology, which are not necessarily implemented in subclinical or early stages of infection, thus potentially contributing to under-diagnosis and under-reporting of infections associated with this bacterium. Recent molecular epidemiology studies have revealed that C. pecorum is genetically diverse and that there may be an association between certain strains and disease in sheep and cattle. Antimicrobial treatment of affected animals has questionable efficacy, justifying development of chlamydia vaccines for livestock. This review summarises current knowledge of the prevalence and impact of C. pecorum infections in sheep and cattle and provides an update on attempts to improve detection, management and treatment of infections by this important obligate intracellular pathogen.

Abstract
The ability of the pathogenic BS isolate of Chlamydia psittaci (ovis) to survive after inoculation into ruminal or abomasal contents, and chlamydial transport medium held at 39 degrees C, was assessed by taking hourly samples which were cultured in mitomycin-treated McCoy cells. The chlamydiae survived for nine hours in the ruminal contents, eight hours in the abomasal contents and for 12 hours in transport medium, when the experiment was concluded. There was a steady decrease in the numbers of the organism in the ruminal and abomasal contents as their pH decreased, but the numbers in the transport medium also decreased without a corresponding change in pH. It is therefore possible that ewes may become infected with C psittaci (ovis) orally via the gastrointestinal tract.

Abstract
Immunohistological detection of chlamydiae in formalin-fixed and paraffin-embedded sections of various organs from several species is described. In a retrospective study, two antisera, a commercially available monoclonal murine antibody (IgMur) and vitelline immunoglobulins (IgY), extracted from the egg yolk of immunized hens, were compared and tested for their applicability under routine condition. Both antisera were applied to tissues from which chlamydiae had been isolated or in which the presence of chlamydiae had been suspected in specially stained sections. Antigen labelling was optimal with the monoclonal antibody. Vitelline immunoglobulins produced some unspecific reactions, especially in lung tissue sections. Because of the antigenic relationship between the vitelline antibodies and tissues of birds, IgY are not suitable for the detection of psittacosis on avian substrates, when using an indirect immunological method. Staining in other tissues e.g. intestine or placenta was of equal quality as that attained with monoclonal antibodies. Depending on the advantages and disadvantages in every individual case, one of the two antibodies may be chosen for further studies. Vitelline antibodies should be preferred with respect to animal welfare.

Abstract
L cells inoculated at multiplicities of infection greater than or equal to 1 inclusion-forming unit of the abortigenic chlamydial strain B577 were destroyed within 10 to 15 days. Upon continued incubation in fresh medium, a few surviving cells repopulated the flasks, and the reemerging cultures remained persistently infected. The persistent state was characterized by cycles of repopulation with a low ratio of infected cells and cycles of extensive cytopathic changes in which greater than 90% of the cells had chlamydial inclusions and which could be delayed or even terminated by penicillin treatment. Immunofluorescence and superinfection during the period of repopulation revealed that the persistently infected cells could adsorb chlamydiae but their multiplication was arrested. This nonpermissive state could be terminated by the specific action of cycloheximide. L cells spontaneously cured from a persistent infection exhibited no change in susceptibility to chlamydiae when compared with normal L cells. However, chlamydiae derived from L cells after 7.5 months of persistence destroyed L-cell monolayers more rapidly and at lower multiplicities of infection than the wild type. This state of chlamydia-host cell interaction could not be established with the arthropathogenic strain LW613 because chlamydial infectivity was lost after the first cytolytic burst of infection in the cell cultures. The persistence described for the strain B577-L-cell system appears to differ from previously described models involving other chlamydial strains.

Abstract
A significant difference has recently been reported in the occurrence of serum antibodies to the lymphogranuloma venereum (LGV) immunotypes of Chlamydia trachomatis in patients with Crohn's disease and controls. In the present study, sera from 107 patients with Crohn's disease, 33 males and 74 females, were tested for antibodies to C. trachomatis by an indirect immunofluorescence test, using two pools of antigens. These pools contained antigens to immunotypes TRIC D-K and LGV 1-3, respectively. None of the patients had IgM antibodies to the organism. IgG antibodies occurred significantly more often in the female than in male patients. No correlation could be demonstrated between activity and duration of Crohn's disease and the results of the antibody tests. For comparison, the sera of 50 puerperal women were studied. No difference in the occurence of IgG antibodies was found between patients and controls, neither when using the two pools of antigen, thus indicating that the antibodies detected had probably been induced by TRIC rather than LGV organisms. To conclude, the study did not indicate an association between Crohn's disease and infection with C. trachomatis.

Abstract
Treatment and control of acute neonatal diarrhea in calves are outlined and discussed. The difficulty in making a definitive etiological diagnosis makes effective treatment and control also difficult and largely empirical. Physiological events in calves with diarrhea are known, and fluid therapy is directed toward treating dehydration and acidosis. Whether affected calves should receive antibacterial agents orally is an open question. Principles of control of diarrhea in calves are outlined and discussed.

Abstract
Ultrastructural changes induced by chlamydial infection of mucosal cells of the ileum of newborn calves after oral inoculation were investigated. Depending on the stage of chlamydial development, the organelles of all infected cells became damaged. The damage was degenerative and included vesiculation of microvilli and swelling of the terminal web of absorptive epithelial cells. The mitochondria were swollen and had fragmented cristae. The endoplasmie reticulum was dilated and vesiculated, and infected cells gradually lost their ribosomes. The lateral junctional complex between infected cells became occasionally dislocated and fragmented. The basal lamina was thrown into folds, became discontinuous and separated from the basal border of the epithelial cells. The nuclei of infected cells were affected last, lost their chromatin pattern, and ultimately became pyknotic.
