[The Relationship of Enterotoxigenic Bacteroides fragilis and Fusobacterium nucleatum Intestinal Colonization with Colorectal Cancer: A Case-Control Study Performed with Colon Biopsies]. / Enterotoksijenik Bacteroides fragilis ve Fusobacterium nucleatum Bagirsak Kolonizasyonunun Kolorektal Kanser ile Iliskisi: Kolon Biyopsileri ile Yapilan Bir Olgu Kontrol Çalismasi.

In recent years, it has been shown that some bacteria may be associated with colorectal cancer (CRC). In this study, it was aimed to investigate the role of Fusobacterium nucleatum and enterotoxigenic Bacteroides fragilis (ETBF) in the etiology of CRC by comparing the amounts of these bacteria in colon biopsy tissues of patients with CRC and healthy individuals. The amounts of F.nucleatum and ETBF were determined by quantitative polymerase chain reaction (qPCR) in colon biopsy samples taken from 35 CRC and 35 healthy individuals, and the results were compared in the patient and control groups. The detection rate and amounts of F.nucleatum were found to be statistically significantly higher in tissues of female patients with CRC compared to male patients (p= 0.003, p= 0.013, respectively). There was no statistically significant difference between the tissues of female and male patients with CRC in terms of detection rate and amount of ETBF (p= 0.521, p= 0.515, respectively). It was found that in the 50-74 age group, the amount of ETBF was statistically significantly higher in women and men with CRC compared to the controls (p= 0.005, p= 0.047, respectively), while the amount of F.nucleatum was statistically significantly higher in female patients compared to controls. However, no difference was found between male patients and controls (p= 0.009, p= 0.083). It was determined that the detection rate and amount of F.nucleatum in the tissues of patients with CRC, regardless of age and gender, were not statistically different from the controls (p= 0.473, p= 0.995, respectively), however, the detection rate of ETBF and the amount of ETBF were found to be statistically significantly higher (p= 0.002, p= 0.004, respectively). It has been determined that ETBF can play a role in the etiology of CRC in both men and women, and F.nucleatum only in women, in the age range of 50-74 years, when routine screenings for CRC are performed.

Firmicutes/Bacteroidetes Ratio in the Gut Microbiota and IL-1ß, IL-6, IL-8, TLR2, TLR4, TLR5 Gene Expressions in Type 2 Diabetes.

BACKGROUND: The aim of this study was to determine the Firmicutes/Bacteroidetes ratio in the gut microbiota and IL-1ß, IL-6, IL-8, TLR2, TLR4 and TLR5 gene expression levels in the blood of adult type 2 diabetes (T2D) patients and compare it with that of adult nondiabetic healthy controls (HC). METHODS: Between May 2016 and April 2017, 99 T2D patients and 99 HCs were enrolled in the study. Bacteroidetes and Firmicutes levels were assessed from stool sample DNA and IL-1ß, IL-6, IL-8, TLR2, TLR4, and TLR5 gene expression levels assesed from blood sample RNA via qPCR from both T2D patients and healthy controls. RESULTS: The Firmicutes/Bacteroidetes ratio detected in the stool of type 2 diabetes patients was found to be higher with a statistically significant difference (p < 0.0001). Gene expression levels of IL-1ß, IL-6, IL-8, TLR2, TLR4, and TLR5 were found to be upregulated. CONCLUSIONS: The highest upregulation was detected in IL-6 with 11 fold in T2D patients comparing with HCs. F/B ratio and gene expression levels were elevated in T2D patients. Firmicutes were positively correlated with studied gene expressions. A better understanding of the complex interaction between gut microbiota, environment, and diabetes will allow for more effective prevention and treatment strategies for T2D.

Point Mutations at gyrA and gyrB Genes of Levofloxacin Resistant Helicobacter pylori Strains and Dual Resistance with Clarithromycin.

BACKGROUND: Spontaneous point mutations in genes encoding gyrA/B subunits of DNA gyrase are responsible for fluoroquinolone resistance. We aimed to determine the clarithromycin and levofloxacin resistance phenotypically in H. pylori strains and to investigate the mutations responsible for levofloxacin resistance and the effects of these mutations on dual antibiotic resistance. METHODS: A total of 65 H. pylori isolates were included. The E-test method was used for the clarithromycin and le-vofloxacin antimicrobial susceptibility test. Real-time PCR was used to detect the point mutations. RESULTS: Twenty-four (36.9%) of 65 H. pylori strains were phenotypically resistant to clarithromycin and 14 (21.5%) to levofloxacin. The phenotypic levofloxacin resistance rate of strains with Asn87Lys and Asp91Asn mutations were significantly higher (gyrA gene) (p < 0.05). The phenotypic levofloxacin resistance rate of strains with Arg484Lys and Asp481Glu mutations were significantly higher (gyrB gene) (p < 0.05). The Asn87Lys mutation increased the risk of phenotypes being resistant to levofloxacin 70.156 times and Asp91Asn mutation increased 125,427 times higher. Seven (10.8%) of 65 H. pylori strains showed dual resistance to both levofloxacin and clarithromycin. The rate of being dual resistant with A2143G mutation (clarithromycin resistance) was found to be significantly higher (p < 0.05). CONCLUSIONS: The Asn87Lys and Asp91Asn mutations in the gyrA gene had a phenotypically enhancing effect on levofloxacin resistance, while the presence of Asp481Glu and Arg484Lys mutations in the gyrB gene did not. The existence of dual resistance was developed with the increase in clarithromycin and levofloxacin resistance rates.

Swabs Containing Tea Tree Oil and Chamomile Oil Versus Baby Shampoo in Patients With Seborrheic Blepharitis: A Double-Blind Randomized Clinical Trial.

PURPOSE: The comparison of the efficacy of swabs containing tea tree oil and chamomile oil and baby shampoo (BS) in the treatment of seborrheic blepharitis was aimed. METHODS: This randomized, double-blind, parallel-group, active control, multicenter clinical trial included patients with seborrheic blepharitis using block randomization (BS, n=23; swabs, n=26). Patients were treated with BS or swabs for 8 weeks followed by 4 weeks of treatment withdrawal. Change in Blepharitis Symptom measure (BLISS), Demodex count, Ocular Surface Disease Index (OSDI) score, Schirmer test, tear breakup time (TBUT), noninvasive TBUT (NI-TBUT), corneal staining, and meibography at different visits (baseline, fourth, , and 12th week) were the main outcome measures. RESULTS: Patients in both groups showed similar baseline parameters (P>0.05). Patients using swabs showed significantly lower BLISS scores compared with patients using BS at the 4th, 8th, and 12th week visits (3.6±6.1 vs. 6.3±4.5 P=0.011; 1.1±2.8 vs. 6.6±6.7, P<0.001; 0.9±2.8 vs. 5.7±6.6, P=0.002, respectively). Patients using swabs showed improvement in OSDI scores after 8 weeks of treatment compared with the baseline visit (P<0.001). Despite a similar Demodex reduction effect in both treatment arms even after 4 weeks of treatment (P<0.001), both treatment modalities did not show any effect on the other parameters. CONCLUSION: Although both swabs and BS showed efficacy for the treatment of seborrheic blepharitis in terms of the Demodex reduction and symptomatic improvement, swabs may provide better symptomatic improvement. Four weeks of treatment discontinuation may not cause any recurrence in the symptoms or Demodex infestation.

A Retrospective Analysis of Anaerobic Bacteria Isolated in 236 Cases of Pleural Empyema and their Prevalance of Antimicrobial Resistance in Turkey.

BACKGROUND: Parapneumonic effusions usually occur secondary to an infection and produce pus (empyema) that accumulates in the pleural space. We aimed to evaluate the prevalence of anerobes in patients with empyema and to assess their resistance patterns for seven antimicrobials. METHODS: Pleural fluid specimens from 236 patients were inoculated on Schaedler agar. Anaerobic bacteria were identified via API 20 A. Susceptibility testing for penicillin, ampicillin + sulbactam, amoxicillin + clavulanate, cefoxitin, clindamycin, metronidazole, and imipenem were performed with the E-test. RESULTS: There were 118 anaerobic bacterial strains detected in 66 (27.9%) of the 236 specimens. Gram-positive anaerobic cocci were detected in 54.23% and the predominant cocci were 41 Peptostreptococcus spp, (34.75%) followed by 17 P. acnes (14.41%) and 6 C. tertium (5.08%). The Gram-negative anaerobes were B. fragilis (28, 23.73%), P. melaninogenica (8, 6.78%), P. intermedia (4, 3.39%), F. nucleatum (6, 5.08%), F. mortiferum (5, 4.24%), and P. asaccharolytica (3, 2.54%). All anaerobic strains were susceptible to ampicillin + sulbactam, amoxicillin + clavulanate, and imipenem. The highest MIC was found to be > 256 µg/mL for penicillin in B. fragilis strains, 128 µg/mL for cefoxitin in P. melaninogenica strains, 32 µg/mL for clindamycin and 64 µg/mL for metronidazole in P. acnes strains. Clindamycin resistance was detected in 46.6% B. fragilis, and 17.6% for P. acnes. Thirty-eight (32.2%) strains produced beta-lactamase. CONCLUSIONS: The use of antimicrobial agents for thoracic empyema should be based on the isolated pathogens and their resistance profiles. Clinicians should be aware of the wide diversity of anaerobic genera and species in cases of pleural empyema.

The relationship between bifidobacteria and allergic asthma and/or allergic dermatitis: a prospective study of 0-3 years-old children in Turkey.

Bifidobacteria are beneficial bacteria for humans. These bacteria are particularly effective at protecting against infectious diseases and modulating the immune response. It was shown that in newborns, the fecal distribution of the colonizing Bifidobacterium species influences the prevalence of allergic diseases. This study aimed to compare the faecal Bifidobacterium species of allergic children to those of healthy children to detect species level differences in faecal distribution. Stool samples were obtained from 99 children between 0 and 3 years of age whose clinical symptoms and laboratory reports were compatible with atopic dermatitis and allergic asthma. Samples were also obtained from 102 healthy children who were similar to the case group with respect to age and sex. Bifidobacteria were isolated by culture and identified at the genus level by API 20 A. In addition, 7 unique species-specific primers were used for the molecular characterization of bifidobacteria. The McNemar test was used for statistical analyses, and p < 0.05 was accepted as significant. Bifidobacterium longum was detected in 11 (11.1%) of the allergic children and in 31 (30.3%) of the healthy children. Statistical analysis revealed a significant difference in the prevalence of B. longum between these two groups (X(2): 11.2, p < 0.001). However, no significant differences in the prevalence of other Bifidobacterium species were found between faecal samples from healthy and allergic children. (p > 0.05). The significant difference in the isolation of B. longum from our study groups suggests that this species favors the host by preventing the development of asthma and allergic dermatitis. Based on these results, we propose that the production of probiotics in accordance with country-specific Bifidobacterium species densities would improve public health. Thus, country-specific prospective case-control studies that collect broad data sets are needed.

A Rare Case of Periprosthetic Joint Infection with Streptococcus dysgalactiae subspecies dysgalactiae.

Periprosthetic joint infection (PJI) is a rare but most vital complication after joint arthroplasty and requires a revision surgery. Synovial fluid analysis is essential in diagnosis of the PJI, and conventional and molecular microbiologic investigations may help in determining the cause of the infection. With this unusual case, we aimed to present the second instance in the literature of PJI of the knee caused by Streptococcus dysgalactiae subspecies dysgalactiae (SDSD). S. dysgalactiae PJI in the literature are commonly Streptococcus dysgalactiae subspecies equisimilis (SDSE), and SDSD mostly infects animals. A farmer with comorbid illnesses who works with cattle and sheep experienced periprosthetic knee joint infection caused by SDSD. Surgical excisional debridement with open washing, decompression, and liner exchange were performed. The identification of the bacteria was done with VITEK MS as SDSD. After 1-year follow-up, the patient has fully recovered without recurrence.

Randomized double-blind trial of wipes containing terpinen-4-ol and hyaluronate versus baby shampoo in seborrheic blepharitis patients.

PURPOSE: To investigate the efficacy of lid wipes (LWs) containing terpinen-4-ol and sodium hyaluronate (Hy-ter®) for the treatment of seborrheic blepharitis compared to baby shampoo (BS). METHODS: This randomized, double-blind, active control, parallel group, multicentre clinical trial included 48 eyes of 48 patients with seborrheic blepharitis who were randomly divided into two treatment arms (1:1, n = 24) using block randomization. LWs or BS were prescribed twice a day for 8 weeks followed by a discontinuation period of 4 weeks. Change in Blepharitis Symptom measure (BLISS), Schirmer's test, tear breakup time (TBUT), noninvasive TBUT (NI-TBUT), ocular surface disease index (OSDI) score, corneal and conjunctival staining, meibography, and Demodex count at different visits (Baseline, 4th, 8th, and 12th week) were the main outcome measures. RESULTS: The baseline values of both groups were similar (p > 0.05). Despite high clinical efficacy in both treatment arms, patients using LWs showed a lower BLISS score at the 8th and 12th-week visit (1.9 ± 2.2 versus 7.2 ± 6.6, p = 0.003; 4.0 ± 1.3 versus 5.8 ± 6.3, p = 0.026). NI-TBUT showed a significant increase starting from the 4th week for patients using LWs and 8th week for patients using BS. Both treatment modalities caused a reduction in the Demodex count after 4 weeks of treatment (p < 0.001). The treatment withdrawal did not cause any recurrence in both treatment arms. CONCLUSION: BS or LWs containing Hy-ter® can be used with good efficacy for the treatment of seborrheic blepharitis. However, LWs may provide a better symptomatic relief compared to BS after 8 weeks of treatment.

Investigation of the Demodex Lid Infestation with in Vivo Confocal Microscopy versus Light Microscopy in Patients with Seborrheic Blepharitis.

AIM: The comparison of the diagnostic efficiency of a reference method (light microscopy [LM] using 10% potassium hydroxide [KOH]) with the use of 100% alcohol to in vivo confocal microscopy (IVCM) for the detection of Demodex eyelid infestation in seborrheic blepharitis patients. METHODS: Eyelashes were epilated from the right eyes for the reference method and the left eyes for the alcohol group in 58 eyes of 29 patients. IVCM was used on the left eyes. The primary outcomes were the number of Demodex mites per lash and the rate of Demodex positivity (≥1 mite). RESULTS: The rate of Demodex positivity was similar among the three groups (KOH: 82.8%, alcohol: 86.2%, IVCM: 72.4%; p >.05). The mean number of mites per lash in the KOH group (1.5 ± 1.3) was higher than in the alcohol (0.9 ± 0.6, p =.041) and IVCM groups (0.9 ± 0.9, p =.036). CONCLUSION: KOH was found to be superior in terms of the quantification of mites compared to alcohol and IVCM.

Effect of scleral lens use on conjunctival microbiota.

AIM: This study aimed to investigate the effect of scleral lens (SL) use on conjunctival microbiota. METHOD: A total of 26 eyes of 26 patients using an SL and 25 eyes of 25 healthy controls were included in the study. The samples were obtained from the lower fornices of the eyes using sterile swabs. For the bacteriological examination, a bacterial culture was obtained by inoculating the samples on chocolate agar, blood agar, MacConkey agar, and fluid thioglycollate medium. After 24-48 h of incubation at 37 0C, the growth of different colonies of bacteria was identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (Bruker MALDI Biotyper). RESULTS: The mean age of the study group was 41.6 ± 19.1 years (18-65); the mean age of the control group was 40 ± 6 (21-62) (p = 0.69). There were 10 male patients and 16 female patients in the study group and 9 male patients and 16 female patients in the control group (p = 0.86). The mean duration of SL use was 13.7 ± 13.4 months (1-42 months). No bacterial growth was observed in 17 (65.4 %) of the 26 eyes in the SL group and 5 (20 %) of the 25 eyes in the control group (p = 0.001). The most commonly observed microorganisms were Staphylococcus epidermidis (S.epidermidis) and Staphylococcus aureus (S.aureus) in both groups. CONCLUSION: SL users were found to have a higher rate of culture negativity in comparison to the healthy controls, suggesting that SLs have a significant effect on conjunctival microbiota.

Bacteroidetes and Firmicutes levels in gut microbiota and effects of hosts TLR2/TLR4 gene expression levels in adult type 1 diabetes patients in Istanbul, Turkey.

AIM: The aim of this study was to determine and compare the levels of both Bacteroidetes and Firmicutes in the gut microbiota and TLR2/TLR4 gene expression in the blood of patients with type 1 diabetes mellitus (T1DM) and healthy individuals. These results may serve as a preliminary assessment to guide future research. METHOD: Between January and October 2014, stool and blood samples were collected from 53 adult T1DM patients and 53 age- and gender-matched healthy individuals. Bacteroidetes and Firmicutes levels were assessed from stool sample DNA and TLR2 and TLR4 expression levels were analyzed via qPCR using RNA from EDTA blood samples from both patients and healthy controls. RESULTS: The amounts of Bacteroidetes and Firmicutes were statistically significantly higher and lower, respectively, in the T1DM group than in the healthy control group (p < 0.001 and p < 0.001, respectively). In addition, the Firmicutes/Bacteroidetes ratios in patients with T1DM were significantly lower than in healthy controls. The TLR4 and TLR2 gene expression levels in T1DM patients were significantly upregulated and downregulated, respectively, compared to those in the control group. CONCLUSION: Our data are the first to show a relationship between T1DM and gut microbiota in our country. In addition, our results provide information about the connections between T1DM, gut microbiota, and TLR2 and TLR4 expression. We believe that Bacteroidetes and Firmicutes in the gut microbiota may play a role in the autoimmune process of T1DM and that these findings should be further investigated in the future.

In Vitro Antifungal Effect of Acrylic Corneal Glue (N-Butyl-2-Cyanoacrylate).

PURPOSE: The purpose of this study was to evaluate the in vitro antifungal effects of n-butyl-2-cyanoacrylate (nB2CA; Histoacryl Blue; B. Braun, Melsungen, Germany) against a variety of different fungal species. METHODS: Inocula taken from suspensions prepared with Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Aspergillus ochraceus, Aspergillus oryzae, Fusarium solanii, Fusarium oxysporum, Trichoderma spp., Rhizomucor spp., Scedosporium apiospermum, Penicillium commune, Phoma glomerata, and Chrysosporium spp. molds and Candida albicans, Candida glabrata, Candida parapsilosis, Candida kruzei, Candida dubliniensis, Candida tropicalis, Candida kefyr, and Trichosporon asahii yeasts were spread on the surface of RPMI1640 agar media. Then, 50 µL of nB2CA was dropped on the surface of these media and they were incubated at 35°C. Observation of a clear zone of inhibition around the nB2CA was regarded as an indicator of the susceptibility of the fungi to nB2CA, and the absence of this zone was interpreted as an indicator of nonsusceptibility. The inhibition zone diameter was measured across the largest clear zone. RESULTS: A zone of inhibition was observed around nB2CA for all of the yeast and mold species except A. flavus, A. oryzae, and Chrysosporium spp. Among molds, the largest zone of inhibition was observed with P. glomerata (25.7 ± 0.6 mm), whereas among yeasts, the largest zone of inhibition was observed with C. kruzei (19.3 ± 1.5 mm). CONCLUSIONS: nB2CA has shown antifungal activity against 18 different mold and yeast species, but not against A. flavus, A. oryzae, and Chrysosporium spp. molds.

Patterns of EPIYA motifs among cagA-positive Helicobacter pylori strains: a case-control study in a Turkish population with Eurasian geographical features.

Geographical variation in the frequency of various gastroduodenal pathologies was shown to be related to the geographical diversity of H. pylori CagA Glu-Pro-Ile-Tyr-Ala (EPIYA) patterns. We examined the EPIYA patterns of H. pylori and the association of EPIYA patterns with gastric cancer (GC) for the first time, to the best of our knowledge, in Turkey. The patient group (PG) contained 60 patients [38 GC and 22 duodenal ulcer (DU) patients]. The control group (CG) was 110 individuals [94 gastritis patients and 16 persons with a normal gastrointestinal system (NGIS)]. Specific primers were used for the detection of cagA including empty-site-positive and EPIYA-A, -B, -C, -D PCR. Bands of EPIYA-A, -B, -C were confirmed by DNA sequencing. One hundred and forty-two (83.5 %) strains [60 in the PG (38 GC, 22 DU), 82 in the CG (72 gastritis, 10 NGIS)] were positive for the cagA gene. EPIYA-C with multiple repeats was detected in 34 (23.9 %) strains, and 22 (64.7 %) were from GC patients. EPIYA-C with one repeat was detected in 89 (62.7 %) strains, and 54 (60.7 %) were from gastritis patients. EPIYT was detected in 10 strains, and EPIYA-D was not detected. The number of EPIYA-C with multiple repeats was significantly higher for the PG than for the CG (P < 0.0001). In GC patients, the number of EPIYA-C with multiple repeats was significantly higher than one repeat (P < 0.0001). In conclusion, our study showed that multiple EPIYA-C repeats increases the GC risk by 30.6-fold and the DU risk by 8.9-fold versus the CG. This indicates that Western-type H. pylori strains in Turkey have similar EPIYA motifs to those of neighbouring countries and Western populations.

Papel del factor neurotrófico de origen cerebral y de la neurotropina-3 en la relación de Chlamydophila pneumoniae con la esquizofrenia / The relationship of Chlamydophila pneumoniae with schizophrenia: The role of brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) in this relationship

Several pathogens have been suspected of playing a role in the pathogenesis of schizophrenia. Chronic inflammation has been proposed to occur as a result of persistent infection caused by Chlamydophila pneumoniae cells that reside in brain endothelial cells for many years. It was recently hypothesized that brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) may play prominent roles in the development of schizophrenia. NT-3 and BDNF levels have been suggested to change in response to various manifestations of infection. Therefore, we aimed to elucidate the roles of BDNF and NT3 in the schizophrenia-C. pneumoniae infection relationship. RT-PCR, immunofluorescence and ELISA methods were used. Fifty patients suffering from schizophrenia and 35 healthy individuals were included as the patient group (PG) and the healthy control group (HCG), respectively. We detected persistent infection in 14 of the 50 individuals in the PG and in 1 of the 35 individuals in the HCG. A significant difference was found between the two groups (p < 0.05). Twenty-two individuals in the PG and 13 in the HCG showed seropositivity for past C. pneumoniae infection, and no difference was observed between the groups (p > 0.05). C. pneumoniae DNA was not detected in any group. A significant difference in NT-3 levels was observed between the groups, with very low levels in the PG (p < 0.001). A significant difference in BDNF levels was also found, with lower levels in the PG (p < 0.05). The mean serum NT-3 level was higher in the PG cases with C. pneumoniae seropositivity than in seronegative cases; however, this difference was not statistically significant (p > 0.05). In conclusion, we suggest that NT-3 levels during persistent C. pneumoniae infection may play a role in this relationship.

Existe la sospecha de que algunos patógenos pueden desempeñar un papel en la patogénesis de la esquizofrenia; en ese contexto, se ha propuesto que la infección persistente causada por células de Chlamydophila pneumoniae presentes en las células endoteliales cerebrales durante muchos años lleva a la inflamación crónica. Recientemente se ha planteado la hipótesis de que el factor neurotrófico de origen cerebral (BDNF, por sus siglas en inglés) y la neurotropina-3 (NT-3) podrían estar implicados en el desarrollo de la esquizofrenia, y se ha sugerido que sus niveles se modifican en respuesta a diversas manifestaciones de la infección. En esta investigación intentamos esclarecer el papel que desempeñan el BDNF y la NT3 en la relación entre la esquizofrenia y la infección por C. pneumoniae. Se utilizaron métodos de RT-PCR, inmunofluorescencia y ELISA. Se incluyeron 50 pacientes con esquizofrenia y 35 individuos sanos como grupo de pacientes (GP) y grupo de controles sanos (GCS), respectivamente. Detectamos una infección persistente en 14 sujetos del GP y en 1 de los del GCS, lo que constituyó una diferencia significativa (p < 0,05). Veinte participantes del GP y 13 del GCS fueron seropositivos para una infección pasada por C. pneumoniae, diferencia no significativa (p > 0,05). No se detectó ADN de C. pneumoniae en ninguno de los dos grupos. Se observó una diferencia significativa entre los grupos en los niveles de NT-3, que fueron muy bajos en el GP (p < 0,001), y de BDNF, inferiores en el GP (p < 0,05). La concentración sérica media de NT-3 fue mayor en los individuos seropositivos para C. pneumoniae en comparación con los seronegativos, pero esta diferencia no alcanzó significación estadística (p > 0,05). Sugerimos que los niveles de NT-3 durante una infección persistente por C. pneumoniae pueden estar implicados en la relación de Chlamydophila pneumoniae con la esquizofrenia.
