Atypical mycobacterial infections are increasingly important in immunosuppressed patients as well as in healthy hosts. The atypical mycobacterium that most commonly affects the skin is Mycobacterium marinum. The infection should be suspected upon the presence of ulcers, nodules or chronic plaques and a history of contact with fresh or salt water. Optimal therapy is yet to be established. We report a case of Mycobacterium marinum infection in a patient receiving immunosuppressive therapy that responded favourably to treatment with doxicycline...

Pleural involvement is a rare presentation of brucellosis. We report a patient referred for the evaluation of fever, right-sided pleural effusion and hilar lymph node enlargement. The pleural fluid revealed exudative characteristics with the predominance of neutrophils. Brucella melitensis was isolated from bone marrow, pleural effusion and blood cultures. The diagnosis was also confirmed by demonstration of a high Brucella agglutinin titre. The patient was successfully treated with rifampicin and doxicycline for three months...

Production of multiply deleted adenoviral (Ad) vectors with increased cloning capacity and reduced immunogenicity to adenovirus gene products requires the concomitant generation of efficient packaging cell lines. High expression levels of the complementing genes must be achieved in a coordinated fashion with viral replication. This is a particularly difficult task in light of the significant cytotoxicity displayed by adenoviral proteins. To this end, we developed a novel adenovirus-based amplicon with an Epstein-Barr virus origin of replication, Ad type 5 (Ad5) inverted terminal repeats, all Ad5 early region 2 (E2) genes, and the early region 4 (E4) open reading frame 6 (ORF6) under the control of a tetracycline-dependent promoter...

Brucellosis is a disease of domestic and wild animals that is transmitted to humans and exists worldwide. We assessed the in vitro activity of moxifloxacin, ciprofloxacin, tetracycline, doxicycline, rifampin, streptomycin and trimethoprim-sulfamethoxazole (TMP/SMX) against 97 Brucella strains isolated from clinical samples, animals and dairy products in Mexico. Fluoroquinolones showed an antibacterial activity similar to that of tetracyclines (MIC(90) 0.5). Other drugs commonly used against brucellosis were less active, such as rifampin (MIC(90) 2...

AIM: To analyse current practice of pharmacotherapy (PT) in outpatient treatment of acute tonsillopharyngitis (ATP) in different regions of Russia. MATERIAL AND METHODS: Case reports for 1333 outpatients (493 male and 840 female, age 16-76 years) with ATP from 7 cities of Russia have been studied. Each ATP case was documented on a special chart to contain the following information: demographic data, history of the disease, bacteriological findings, PT regimens, complications, treatment outcomes...

Eosinophilic pustular folliculitis (EPF) is an unusual disease, first described in adult East Asians in 1970 by Ofuji. It is characterized by follicular papules and pustules tending to coalesce and form plaques involving the trunk, face and extremities. In recent years, it has been often associated with human immunodeficiency virus (HIV) infection or with immunosuppressed and/or oncohaematological patients. EPF has been described in immunocompetent adult caucasian patients only occasionally. The diagnosis requires clinical and microbiological features such as sterile folliculitis and histopathological findings characterized by folliculitis and perifolliculitis with eosinophilic infiltrate...

The bite of a rat can transmit diverse micro-organisms; however, the development of health measures and the improved conditions of habitability of homes have meant that the infectious diseases transmitted by the aggressions of these animals are infrequent in industrialised countries. In occasional circumstances this type of aggression can still take place, especially in depressed areas on the periphery of big cities and in uninhabited premises, this being a possibility that it is advisable to bear in mind. The case is presented of fever due to a rat bite in a patient who was attacked while cleaning an industrial premise...

AIM: To ascertain regularities of development of cellular immunity in patients with Astrakhan fever (AF) with reference to AF severity, treatment and course. MATERIAL AND METHODS: Cellular factors of immunity--relative and absolute contents of T-lymphocytes (early and late), T-helpers and T-suppressors, B-lymphocytes, neutrophils (early and late)--were studied in 75 patients with AF (63 patients with moderate and 12 patients with severe disease) in the course of the disease progression (weeks 1-5)...

Basic fibroblast growth factor (FGF-2) is a secretory protein that lacks a signal peptide. Consistently, FGF-2 has been shown to be secreted by an ER-Golgi-independent mechanism; however, the machinery mediating this process remains to be established at the molecular level. Here we introduce a novel experimental system based on flow cytometry that allows the quantitative assessment of non-classical FGF-2 secretion in living cells. Stable cell lines have been created by retroviral transduction that express various kinds of FGF-2-GFP fusion proteins in a doxicyclin-dependent manner...

The authors present a case of a 20-year old student from Belgrade, who was admitted to the Institute of Infectious Diseases with fever, muscle and spine pains, strong headache and malice. During the clinical examination bilateral sacroileitis was found. Serological analyses confirmed brucellosis. Epidemiological data showed that she lived in Kosovo and Metohia in 1997, where she consumed diary products from domestic animals; this might be the reason of the acquired infection. With appropriate antibiotic therapy (aminoglycoside, doxicyclin, rifampicin), symptomatic therapy and rehabilitation the disease had favourable outcome; there was no recidive...

65 patients with knee and hip joints osteoarthrosis with concomitant urinary infection and/or irritable colon syndrome were randomized into three groups: group 1 (21 patients) received doxicyclin 200 mg/day with nistatine for three weeks with 3-week interval between the courses and bifidum-bacterin administration between the courses and after the treatment; group 2 (22 patients) received biseptol 1920 mg for 3 weeks then 960 mg 10 days a month; group 3 (22 patients) consisted of controls who received no antibacterial drugs...

As a result of long-standing screening of chemopreparations of anti-rickettsiosis action in-vitro and in-vivo experiments and their clinical evaluation in the treatment of R. of any etiology, it is established that the most effective ones are those of the 4 groups: tetracyclines (doxicycline, minocyclines), ansamicines (rifampicine), ftorchinolones (cyprofloxacine, ofloxacine, pefloxacine) and the new generation of macrolides (asitromicine, klaritromicine). Since all the studied preparations have only rickettsiosis-static effect, a promising way to finding a rickettsiocidic preparation capable of preventing a possible persistence of a relevant agent in a human body is a combined application of highly effective chemopreparations (doxicycline, in particular) or pefloxacine with lysosomal alkalinizing drugs (chlorochin, ammonium chloride or amantadine)...

The first case of Q fever endocarditis that has been diagnosed in Mexico is presented. A 10-year-old girl with discrete subaortic stenosis (SAS) and patent ductus arteriosus (PDA) was seen in December of 1996 with fever, hepatomegaly and splenomegaly. She presented also anemia, leukopenia, hypergammaglobulinemia, positive rheumatoid factor, cryoglobulinemia, antinuclear and anticytoplasmic antibodies (anti-RNA-proteins and anti-DNA). An aortic valve vegetation was seen by echocardiogram. Blood-cultures were negative...

OBJECTIVES: To study the clinical manifestations of 86 patients with Mediterranean Boutonneuse Fever who were admitted in a University General Hospital. PATIENTS AND METHODS: Between 1986 and 1994 we studied retrospectively the clinical manifestations, evolution and complications of 86 patients with Mediterranean Boutonneuse Fever. Diagnosis was based on clinical and serological findings. RESULTS: We studied a total of 86 patients (64 males; 22 females) with a mean age of 55 years...

A colony (N83) of the vaccine strain of Francisella tularensis (15/10) and a strain (N268) isolated from a water sample in nature were revealed for susceptibility to cultivation at 42 degrees C. Both strains had low virulence for white mice and were avirulent for guinea pigs but possessed high immunogenicity in these animals. The spontaneous mutant of vaccine strain 15/10 showed resistance to doxicycline and rifampicine (15/10 Dox (r)40 Rif (r)40). The obtained mutant had biological characteristics similar to the parent vaccine strain...

190 V. cholerae cultures isolated by the specialized antiepidemic brigade of the Rostov-on-Don Research Institute for Plague Control in the Khasavyurt, Babayurt and Novolaksk regions of Daghestan in August-October 1994. All isolated strains were typical with respect to their morphological and cultural properties and could be agglutinated (with the exception of one strain) to the titer or half-titer with diagnostic cholera serum and Ogawa serum. 4 strains had signs of RO-dissociation, 4 strains were agglutinated with Inaba serum in a low titer...

A high degree of resistance to cholera diagnostic phages and carriership of prophages characteristic of V. cholerae eltor strains vct+ were shown to be the specific features V. cholerae isolated in Daghestan during the period of June-October 1994. Among the strains under study, isolated respectively in 12 and 18 out of 19 regions of Daghestan, a high proportion was found to have resistance to tetracycline (65%) and chloramphenicol (28.6%). Moreover, some strains were found to be resistant to furagin and erythromycin...

Investigated were the acute toxicity, serum concentrations, and residual amounts of doxycycline in broiler chickens. It was found that the LD50 of doxycycline when applied via the crop to week-old broiler birds was 2500 mg/kg mass. The amount of 0.005 g/kg mass given orally to birds led to serum concentrations that on the eighteenth hour were found to drop up to subtherapeutic ones. When applied with the drinking water at the rate of 0.02 to 0.04 g l or kg feed it was well absorbed as early as the first hours...

Human brucellosis can be managed with different therapeutic measures. The present study compares the therapeutic efficacy of the classical treatment with streptomycin, doxicyclin and cotrimoxazole, every one of the treatment regimes being applied to 19 patients with acute brucellosis. The results do not demonstrate an advantage of the new association over the classical treatment. Relapses, time elapsed until the patient was afebrile and drug tolerance were similar for both treatments. The classical treatment has a lower cost but the new association implies more patient comfort because the number of pills to be ingested daily is reduced to less than half, a fact that could make it the treatment of choice...

The clinical behaviour and post-operative course of 60 patients who had undergone obstetrics or gynaecological surgery is compared. In 30 cases (20 obstetric and 10 gynaecological), antibiotic prophylaxis took the form of a single i.m. injection of 600 mg of lincomycin and 80 mg of gentamycin, 30 minutes before the operation. In the remaining 30 cases (20 obstetric, 10 gynacological), the antibiotic cover was administered postoperatively by i.v. injection of doxicyclin (100 mg every 12 hours for 3 days and 100 mg every 12 hours per os for a further 2 days)...
