Four media, Eagle's minimal essential medium with 10% fetal bovine serum (MEM/FBS), tryptic soy broth (TSB), 2-SP, and 4-SP, were compared for their ability to maintain the viability of Chlamydia trachomatis at 4 degrees C, -20 degrees C, -70 degrees C, and -176 degrees C (liquid nitrogen) over a
Chlamydia pneumoniae (CP) is associated with induction and exacerbation of asthma. CP infection can induce allergic airway sensitization in mice in a dose- and time-dependent manner. Allergen exposure 5 days after a low dose (mild-moderate), but not a high dose (severe) CP infection induces antigen
Topical microbicides for prevention of sexually transmitted diseases (STDs) would be especially useful for women who are not able to persuade their partner(s) to take precautions. Many topical microbicides are in various stages of development, based on a variety of active ingredients. We
The major outer membrane protein of Chlamydia trachomatis has been extensively studied and is still considered one of the most promising candidates for development of a synthetic vaccine. Neutralizing epitopes in variable domains I, II, and IV have already been reported. In variable domain I,
OBJECTIVE: In this study, the survival and recovery of Chlamydia pneumoniae (Cp) strains TW-183, AR-39, AR-388 and CWL-029 were measured after inoculation on glass, stainless steel, FormicaR laminate, paper, fabric and human skin. METHODS: Inoculum in throat washes from healthy volunteers was
Tilmicosin is a widely used antibiotic in veterinary applications. Its antimicrobial activity is ranged from Gram-positive and some Gram-negative bacteria towards activities against Mycoplasma and Chlamydia. Adsorption affinity of tilmicosin antibiotics towards bovine serum albumin was investigated
Bovine IgG and albumin concentrations were determined from serum and semen of 59 bulls that were divided into 4 groups: 35 non-infected bulls (Group 1); 10 with vesiculitis due to Corynebacterium pyogenes (Group 2); 10 bulls with orchitis due to Chlamydia psittaci (Group 3); and 4 bulls with
The lipid compositions of (i) monkey kidney (MK-2) cells cultivated in Eagle's minimal essential medium (MEM) with 5% calf serum, (ii) MK-2 cells cultivated in Waymouth medium supplemented with 20 mug of sodium oleate and 2 mg of bovine albumin per ml, (iii) Chlamydia psittaci strain 6BC grown in
Chlamydia trachomatis (L2) adhere to and infect chorionic membrane in vitro. Similarly, chlamydiae pre-exposed to either chorion homogenate, newborn calf serum or pure bovine serum albumin display a higher infectivity against mouse fibroblast cells in vitro. Polyacrylamide gel electrophoresis of the
Intracytoplasmic inclusions containing Chlamydia psittaci were isolated by a newly established method. Infected L-cells at 20 h after infection were suspended in 0.25 M sucrose-tris(hydroxymethyl)aminomethane buffer containing ethylene-diaminetetraacetic acid, homogenized in a Dounce tissue grinder,
Chlamydia trachomatis is normally grown in McCoy monolayer coverslip cultures using partially defined media containing foetal calf serum at concentrations up to 10% (v/v). Omission of the serum decreased the number of inclusions produced by infecting the McCoy cells with a standard inoculum of a
BACKGROUND
Obligate intracellular pathogens belonging to the Chlamydiaceae family possess a number of mechanisms by which to manipulate the host cell and surrounding environment. Such capabilities include the inhibition of apoptosis, down-regulation of major histocompatability complex (MHC) and
Intracellular Chlamydia (C.) bacteria cause in cattle some acute but rare diseases such as abortion, sporadic bovine encephalomyelitis, kerato-conjunctivitis, pneumonia, enteritis and polyarthritis. More frequent, essentially ubiquitous worldwide, are low-level, asymptomatic chlamydial infections in
BACKGROUND
Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease characterized by inflammatory injury and bile duct destruction. Recent studies suggest that Chlamydia pneumoniae could be associated with the development of PBC. The aim of this study was to determine the
BACKGROUND
Chlamydia psittaci (Cp) is a respiratory pathogen capable of inducing acute pulmonary zoonotic disease (psittacosis) or persistent infection. To elucidate the pathogenesis of this infection, a translational large animal model was recently introduced by our group. This study aims at
