The explosive, destructive course of Bacillus endophthalmitis has been attributed to the production of toxins during infection. In this study we analyzed the contribution of toxins controlled by the global regulator plcR to the pathogenesis of experimental Bacillus endophthalmitis. Isogenic plcR-deficient mutants of Bacillus cereus and Bacillus thuringiensis were constructed by insertional inactivation of plcR by the kanamycin resistance cassette, aphA3. Rabbit eyes were injected intravitreally with approximately 100 CFU of wild-type B. cereus or B. thuringiensis or a plcR-deficient mutant. The evolution of endophthalmitis resulting from each plcR-deficient mutant was considerably slower than that caused by each wild-type strain. Retinal function was not eliminated until 42 h postinfection in rabbits with endophthalmitis caused by the plcR-deficient mutants, whereas wild-type infections resulted in a complete loss of retinal function within 18 h. The intraocular inflammatory cell influx and retinal destruction in plcR-deficient endophthalmitis approached the severity observed in wild-ype infections, but not until 36 h postinfection. Gross and histological examinations of eyes infected with plcR mutants demonstrated that the anterior and posterior segment changes were muted compared to the changes observed in eyes infected with the wild types. The loss of plcR-regulated factors significantly attenuated the severity of Bacillus endophthalmitis. The results therefore suggest that plcR may represent a target for which adjunct therapies could be designed for the prevention of blindness during Bacillus endophthalmitis.

Borrelia burgdorferi causes Lyme disease in humans. The genome of the sequenced type strain B31 MI consists of a linear chromosome, 12 linear plasmids, and 9 circular plasmids. Previous studies by other investigators indicated that some of these plasmids are essential for the survival of the spirochetes in vivo but not in vitro. We have studied plasmid stability during in vitro growth at 23 and 35 degrees C, conditions that approximate the temperatures of the tick vector and the mammalian host, respectively. Starting with two clones that have all 21 plasmids, we investigated plasmid maintenance within the population and on a clonal level. After three passages (27 generations), the cultures were no longer homogeneous and some derivative clones had already lost multiple plasmids. Despite this, one of six clones analyzed after 25 passages (225 generations) retained all but one plasmid (cp9) and was able to complete the mouse-tick-mouse infectious cycle. We analyzed protein composition and regulation of gene expression of clones differing in plasmid content after serial passages. All clones tested exhibited temperature-regulated expression of several proteins, including OspC. In addition, analysis of cultures inoculated from frozen stocks suggests that freezing and/or thawing contributes to heterogeneity in the outgrowth population with respect to plasmid content. Our investigations show that in vitro propagation of a clone leads to a heterogeneous population but that virulent clones can persist through extended passage. We therefore conclude that isogenicity of clones must be confirmed irrespective of their in vitro passage history.

Th1 immune response is essential in the protection against mycobacterial intracellular pathogens. Lipoproteins trigger both humoral and cellular immune responses and may be candidate protective antigens. We studied in BALB/c mice the immunogenicity and the protection offered by the recombinant 27-kDa Mycobacterium tuberculosis lipoprotein and the corresponding DNA vaccine. Immunization with the 27-kDa antigen resulted in high titers of immunoglobulin G1 (IgG1) and IgG2a with a typical Th1 profile and a strong delayed hypersensitivity response. A strong proliferation response was observed in splenocytes, and significant nitric oxide production and gamma interferon secretion but not interleukin 10 secretion were measured. Based on these criteria, the 27-kDa antigen induced a typical Th1-type immune response thought to be necessary for protection. Surprisingly, in 27-kDa-vaccinated mice (protein or DNA vaccines) challenged by M. tuberculosis H37Rv or BCG strains, there was a significant increase in the numbers of CFU in the spleen compared to that for control groups. Furthermore, the protection provided by BCG or other mycobacterial antigens was completely abolished once the 27-kDa antigen was added to the vaccine preparations. This study indicates that the 27-kDa antigen has an adverse effect on the protection afforded by recognized vaccines. We are currently studying how the 27-kDa antigen modulates the mouse immune response.

OBJECTIVE: New antiretroviral strategies aim to reduce plasma HIV RNA (viral load) to below the limits of detectability of assays with the objective of reducing viral replication in order to stop or reverse the pathogenic process and prevent development of drug resistance. First use of a protease inhibitor might offer the most realistic chance of achieving this aim. Our objective was to study the virological response to protease inhibitors in patients taking them for the first time. METHODS: A total of 901 patients from a large outpatient clinic were followed a mean of 15 months from the time of starting a protease inhibitor until 1 May 1998. Viral load and CD4 cell count measurements were made on average every 34 days. RESULTS: Overall there was a 79% [95% confidence interval (CI), 76-82] probability of the patients achieving a viral load < 500 copies/ml by 24 weeks after starting the protease inhibitor. In a multiple Cox regression model, those with lower initial viral load [relative hazard (RH), 0.72; P < 0.0001], higher CD4 cell count (RH, 1.07; P = 0.002), those starting other new drugs at same time as the protease inhibitor (RH, 1.46 for two versus none; P = 0.003), those who were antiretroviral-naive, and those using indinavir or nelfinavir were more likely to achieve such levels. In those 651 patients achieving viral load < 500 copies/ml within 24 weeks, there was an estimated 53% (95% CI, 51-55) probability of rebound of viral load to > 500 copies/ml by 52 weeks from the first undetectable value. Again, those who had started other new drugs at the same time as the protease inhibitor (RH, 0.57; P = 0.003 for starting two versus none) tended to experience a lower probability of viral load rebound, as did those with higher initial CD4 cell count (RH, 0.87 per 100 x 10(6)/l higher; P = 0.0007). Those who took saquinavir achieved less durable virological responses than those who took other protease inhibitors. CONCLUSIONS: Starting protease inhibitor therapy with two other new antiretroviral drugs simultaneously with protease inhibitor therapy offers a better best chance of achieving sustained viral load < 500 copies/ml than starting fewer new drugs.

Optimal tumor necrosis factor induction by Plasmodium falciparum requires the highly localized release of parasite products.

Overproduction of tumor necrosis factor (TNF) has been linked with the pathogenesis of Plasmodium falciparum malaria. Here, we examined why the high levels of TNF-inducing activity associated with P. falciparum-parasitized erythrocytes (PE) appear to be lost after cell lysis. Static coculture of PE and peripheral blood mononuclear cells (PBMC), with or without separation by porous membranes, demonstrated that rupture of live PE in the presence of responder cells was required for optimal TNF induction. Although the insoluble fraction of lysed PE was found to partially inhibit TNF responses, supernatants prepared from large numbers of lysed PE still contained only low levels of TNF-inducing activity, which showed no evidence of instability. A dramatic reduction in TNF levels resulted when noncytoadherent PE lines were maintained under low-cell-proximity conditions by suspension coculture. This reduction was much less marked with PE capable of adhering to PBMC, despite the fact that cytoadherent and noncytoadherent parasite lines induced comparable levels of TNF in high-cell-proximity, static coculture. These results suggest that rupture of PE in a highly localized setting, facilitated by either static coculture or the more biologically relevant phenomenon of cytoadherence to PBMC, can result in considerable enhancement of the P. falciparum-induced TNF response.

Hair loss is genetically influenced, but it is always difficult to predict. Overall, more than 50% of US men suffer hair loss by their age of 45. Men are more likely to lose hair than women. Hair Million offers an alternative solution to hair loss problems. Anecdotal evidence and personal experiences indicate the efficacy of this herbal blend in improveming age-related hair thinning and hair loss for a number of people who take it. The mechanism of action as to how Hair Million works to help stop hair loss, and promote hair growth is totally unknown. It is only known by anecdotal observations. There has been no clinical trials nor placebo controlled statistical analysis on the efficacy of Hair Million on hair loss and hair growth. Propecia is a clinically tested drug for the purpose of reversing hair loss.
