Tetracyclines are active in vitro against most urinary tract pathogens, Chlamydia, Mycoplasma pneumoniae, Brucella, rickettsiae, and Nocardia. Chloramphenicol is used primarily for anaerobic infections, Haemophilus influenzae meningitis, and infections due to Salmonella typhi. Erythromycin is active in vitro against M. pneumoniae, Streptococcus pneumoniae, and group A beta-hemolytic streptococci. Erythromycin may be used as prophylactic therapy for subacute bacterial endocarditis and for recurrence of acute rheumatic fever in patients who are allergic to penicillin. Clindamycin should be used only for the treatment of anaerobic infections. Tetracycline may cause gastrointestinal upset; phototoxic dermatitis; hepatitis, especially in pregnant females; discoloration of teeth and bone dysplasia in the human fetus and children; and suprainfections, especially oral and anogenital candidiasis. Tetracycline should be used with caution in patients with renal insufficiency. The most important toxic effect of chloramphenicol is bone marrow suppression, which is dose related and idiosyncratic. The incidence of undesirable side effects associated with the use of erythromycin is low. Gastrointestinal irritation is the most common; cholestatic hepatitis may occur with erythromycin estolate. Pseudomembranous colitis is the most important toxic effect associated with clindamycin.

In situ hybridisation (ISH) is based on the complementary pairing of labelled DNA or RNA probes with normal or abnormal nucleic acid sequences in intact chromosomes, cells or tissue sections. Compared with other molecular biology techniques applicable to anatomical pathology, ISH enjoys better rapport with histopathologists because of its similarity to immunohistochemistry. It has the unique advantage over other molecular biology techniques--largely based on probe hybridisation with nucleic acid extracted from homogenised tissue samples--of allowing localisation and visualisation of target nucleic acid sequences within morphologically identifiable cells or cellular structures. Probes for ISH may bear radioactive or non-radioactive labels. Isotopic probes (3H, 32P, 35S, 125I) are generally more sensitive than non-isotopic ones but are less stable, require longer processing times and stringent disposal methods. Numerous non-isotopic labels have been used; of these biotin and digoxigenin are the reporters of choice. Optimised non-isotopic systems of equivalent sensitivity to those which use radioactive-labelled probes have been described. In ISH, finding the optimal balance between good morphological preservation of cells and strong hybridisation signals is crucial. Tissue fixation and retention of cytoskeletal structures, unfortunately, impede diffusion of probes into tissues. ISH sensitivity is also influenced by inherent properties of the probe and hybridisation conditions. Although ISH is largely a research tool, it is already making strong inroads into diagnostic histopathology. It has been applied for the detection of various infective agents particularly CMV, HPV, HIV, JC virus, B19 parvovirus, HSV-1, EBV, HBV, hepatitis delta virus, Chlamydia trachomatis, salmonella and mycoplasma in tissue sections.(ABSTRACT TRUNCATED AT 250 WORDS)

A red-tailed hawk (Buteo jamaicensis) with signs of respiratory distress and diarrhea was captured in the Manchac Wildlife Management Area, Louisiana (USA) and died the following day. At necropsy, the carcass was emaciated and there were splenomegaly, and fibrinous pericarditis, airsacculitis, and perihepatitis. Microscopically, there were fibrinous pericarditis and airsacculitis, myocardial necrosis, necrotizing hepatitis, splenic necrosis with reticuloendothelial cell hyperplasia, interstitial pneumonia and focal pancreatic necrosis. Intracytoplasmic chlamydial inclusion bodies were noticed in macrophages in the fibrinous exudate covering air sac and pericardium, and in spleen, liver, heart, lung, and pancreas. Schizonts compatible with a Sarcocystis sp.-like protozoon were present in the walls of air capillaries in the lung. A Chlamydia sp.-like organism was isolated in embryonating chicken eggs and cell culture and identified as C. psittaci with immunofluorescent staining.

To evaluate the prevalence of hepatitis-B-virus (HBV)-markers in STD patients and the significance of promiscuous heterosexual activity as a risk factor for the transmission of HBV, a serological screening was performed in 499 patients, in addition to the routine STD diagnostic programme. Two groups of patients were evaluated: group 1 (120 patients) was drawn from the STD clinic of the Public Health Office (PHO), group 2 (379 patients) from a private STD outpatient clinic. Promiscuous activity was reported significantly more often by persons of group 1 than by those attending the private clinic (59.3% vs. 5.1%). The infection rate of gonorrhea, syphilis and Chlamydia trachomatis was high in patients of the PHO (46.7%, 35.3%, 27.5%) whereas most of the STDs were seldom ascertained in patients of the private clinic (1.1%, 0%, 5.6%). Similar to other STDs, the prevalence of HBV markers differed significantly between patients of the PHO and those of the private clinic (33.3% vs. 6.3%; p = .0000). Comparison of HBV and other STDs showed the highest coincidence of HBV markers in patients with serological evidence of syphilis (44.2%), and in one third of patients with Neisseria gonorrhoeae as well as HIV infection. The data obtained in the present study demonstrate that also in Austria, in addition to homosexual preference and drug abuse, promiscuous heterosexual activity must be considered a substantial risk factor for the transmission of HBV.

An instrument for the automation of in situ hybridization and immunohistochemistry has been developed. This machine is capable of analyzing 20 microscope glass slides via all of the steps required for colorimetric in situ hybridization or immunohistochemistry. The slides are placed specimen-side down on a specialized Teflon slide-holder set in the reaction chamber of the machine. The system uses a unique type of capillary action between the slide and the holder. The holder has two small holes and is designed to apply, incubate and sequentially add and remove reagents from the slide surface. The system performs the complete processes of in situ hybridization and immunohistochemistry from dewaxing to colorization. Some applications were carried out using this instrument. Cultured cells infected with cytomegalovirus, adenovirus, or herpes simplex virus were hybridized with homologous biotinylated probes, and showed strong purple signals with alkaline phosphatase in the presence of nitroblue tetrazolium and 5-bromo-4-chloro-3-indolyl phosphate. Automatic in situ hybridization using other colorimetric detection systems (e.g., peroxidase-labeled probes/diaminobenzidine/H2O2) was also examined in cells infected with Chlamydia trachomatis and in paraffin-embedded hepatic tissue sections from patients with hepatitis. For conventional immunohistochemical staining, formalin-fixed and paraffin-embedded tissues were used. Glial fibrillary acidic protein and gamma-immunoglobulins were detected automatically in human brain white matter and tonsillar tissues, respectively, as peroxidase-based reddish signals. The intensity of staining was equal to that achieved by manual methods.

A 55-year-old female was admitted to our hospital because of high fever, nonproductive cough and dyspnea. Initially she had been treated with cephem antibiotics by a local doctor. However, acute respiratory failure due to severe pneumonia developed. The partial pressure of oxygen in arterial blood was 55.5 Torr. Her chest X-ray revealed wide-spread infiltrates with air bronchograms throughout the entire left lung, and pleural effusions were also present in the chest CT scan. Because the patient had a history of the contact with birds, we suspected psittacosis and administered Minocycline immediately. As a result, her clinical condition improved and the abnormal shadow on the chest X-ray film improved markedly in three days. Because the serum titer of a complement fixation test against Chlamydia rose to 1:512, we made the diagnosis of psittacosis. In addition, femoral muscle pain, and a high level of serum GOT, GPT, CK, Aldolase and Myoglobin indicated hepatitis and myositis. In the lung tissue specimens obtained by TBLB performed on the 10th hospital day, slight interstitial pneumonia and intracellular inclusion bodies were found by light microscopy and Chlamydial agents were found electron microscopically.

Hepatic involvement is considered a rare complication of psittacosis. Occurrence of icteric hepatitis as the cardinal manifestation of the disease has been rarely reported. We describe two members of a family infected by psittacosis, in whom icteric hepatitis was the prominent expression of the disease. The diagnosis of psittacosis was confirmed by isolation of the pathogen and by detection of serum antibodies to Chlamydia species. No serological evidence for acute TWAR infection was found. Chlamydia psittaci was also isolated from the family's parrot.

We report a retrospective series of 20 cases of peri-hepatitis diagnosed using the laparoscope. They were all young women who were nulliparous or primiparous. In eight cases, the dominant clinical picture was of acute cholecystitis. In the other cases, asymptomatic peri-hepatitis was discovered when the laparoscope had been used to try to diagnose acute salpingitis. Chlamydia trachomatis is the principal aetiological agent (in 18 cases) and it has overtaken the gonococcus which was the common one in early publications but here was responsible for only one case. Treatment with tetracyclines or quinolones always brings about a cure. Whenever a young woman complains of pain in the right hypochondrium, one has to think of this infection as well as diagnosing and treating the associated salpingitis early.

Genital infections in impoverished countries take a heavy toll both in the etiology of childlessness and in pregnancy-related morbidity, both for the carrier (mother) and the passenger (fetus/newborn). Tubal damage is by far the most common single etiology in cases of childlessness. Among the three factors principally contributing to childlessness, infertility, pregnancy wastage and child loss, tubal infertility is the predominant one. Prevalence figures of N. gonorrhoeae among women in reproductive ages range between 5 and 15% in several countries. Similar figures prevail among pregnant/puerperal women. Preliminary figures indicate that prevalence of Chlamydia trachomatis is similar. Genitally acquired infections during pregnancy contribute to pregnancy wastage in the second and third trimesters of pregnancy. There is virtually no data to support that HBV, HSV and HPV significantly contribute to transmitted intra-uterine disease leading to pregnancy wastage. In the third category of childlessness, child loss, HSV and HIV play a well-known role. Maternal and neonatal morbidity is adversely affected by genital infections acquired during pregnancy. While hepatitis in some places is an important contributor to maternal mortality and morbidity, other viral diseases like HSV and HPV do not appear important in pregnancy-related maternal morbidity. Gonorrhea and chlamydia infection give few maternal problems during pregnancy but may be more important as a cause of puerperal endometritis-myometritis, which constitutes one of the leading causes of maternal death in many developing countries. The fetal/neonatal infant morbidity is affected by gonorrhea and chlamydia infection, while HSV is less frequent but extremely serious when it appears.(ABSTRACT TRUNCATED AT 250 WORDS)

Three-hundred-eighty-four leprosy patients were clinically examined for sexually transmitted diseases (STD) in north and northeastern India, revealing a high incidence (5.2%) of STD among them. Eighteen males, one female, and one eunuch were found to have chancroid ulcer, gonococcal urethritis, lymphogranuloma inguinale, and primary chancre. Of these patients, only 100, selected randomly, could be screened serologically for STD due to Treponema pallidum, herpes simplex (type 1 and 2), Entamoeba histolytica, hepatitis-associated virus, cytomegalovirus, Chlamydia trachomatis and human immunodeficiency virus (HIV); 100 control sera were included for comparison. In addition, sera from another 133 normal subjects and another 176 lepromatous patients were also screened for HIV antibody. Thus, a total of 233 normal sera and 276 leprosy sera were tested for HIV antibody. Although our leprosy patients have shown significantly high incidences of clinical STD and also high seropositivity against T. pallidum, herpes-simplex viruses types 1 and 2, hepatitis-associated virus, and cytomegalovirus, the search for antibody against HIV was negative. Our clinical and serological data suggest promiscuity in our patient population. The absence of HIV antibody in this high-risk population, however, seems to be an enigma.
