Abstract
Background Epstein-Barr virus (EBV) is a widely disseminated herpesvirus for which antibodies have been demonstrated in over 90% of adults worldwide. After subclinical primary EBV infections, as well as after infectious mononucleosis, the virus can be shed in saliva for a prolonged period of time. Aim Diseases and disorders that can induce EBV salivary shedding include mental disorders and sex, connective tissue disease, multiple sclerosis, systemic lupus erythematosus, malaria and HIV infection. Since the occurrence of EBV in saliva during acute infectious diseases has not yet been systematically researched, we aimed to investigate the possible relationship between acute infectious diseases and salivary shedding of EBV. Material and methods This pilot cross-sectional study included consenting adults hospitalized for acute infectious conditions and their peers free of acute infectious diseases. A total of 40 patients with acute infectious diseases were enrolled, along with 41 adults free of acute infections. Peripheral venous blood samples for serodiagnosis and saliva samples for EBV PCR testing were collected from both groups. We fitted logit and general linear models to proportions and to ln (viral copy counts) to generate adjusted proportions and geometric mean values in the two groups of subjects. We used SAS for Windows 9.4. Results The most common acute infectious disease was COVID-19 pneumonia, followed by hemorrhagic fever with renal syndrome. Crude proportions of people with positive serological test results and those with saliva viral shedding were similar in the two groups. Conclusions The presented preliminary data do not indicate acute infectious conditions as a marked "contributor" in increasing salivary EBV shedding.

Abstract
Interactions between coinfecting pathogens have the potential to alter the course of infection and can act as a source of phenotypic variation in susceptibility between hosts. This phenotypic variation may influence the evolution of host-pathogen interactions within host species and interfere with patterns in the outcomes of infection across host species. Here, we examine experimental coinfections of two Cripaviruses-Cricket Paralysis Virus (CrPV), and Drosophila C Virus (DCV)-across a panel of 25 Drosophila melanogaster inbred lines and 47 Drosophilidae host species. We find that interactions between these viruses alter viral loads across D. melanogaster genotypes, with a ~3 fold increase in the viral load of DCV and a ~2.5 fold decrease in CrPV in coinfection compared to single infection, but we find little evidence of a host genetic basis for these effects. Across host species, we find no evidence of systematic changes in susceptibility during coinfection, with no interaction between DCV and CrPV detected in the majority of host species. These results suggest that phenotypic variation in coinfection interactions within host species can occur independently of natural host genetic variation in susceptibility, and that patterns of susceptibility across host species to single infections can be robust to the added complexity of coinfection.

Abstract
OBJECTIVE To assess the oral shedding and viremia of Epstein-Barr virus (EBV) in HIV-positive patients and their relationship with oral hairy leukoplakia (OHL). METHODOLOGY A total of 94 HIV-positive patients were included in the study, in which blood and saliva samples were collected for EBV quantification. Data on gender, age, time of HIV seropositivity, combined antiretroviral therapy (cART), CD4+ T-cell counts, and HIV viral load were collected. OHL diagnosis was based on histopathological examination and EBV in situ hybridization. RESULTS The EBV load in the 94 HIV-positive patients was higher in saliva than in blood (2.4 and 1.6, respectively), and there was a positive correlation between EBV oral shedding and viremia (p = 0.001). Twenty (21.27%) patients had OHL and also a higher EBV load in saliva (mean log10 = 3.11) compared to those who had no OHL (p = 0.045). Presence of OHL was only associated with age (p = 0.030). CONCLUSION In HIV-positive patients, the presence of OHL was associated with EBV oral shedding but not with viremia, regardless of the amount of circulating CD4+ T cells.

Abstract
The Epstein–Barr virus (EBV) is a well-adapted human virus, and its infection is exclusive to our species, generally beginning in the childhood and then persisting throughout the life of most of the affected adults. Although this infection generally remains asymptomatic, EBV can trigger life-threatening conditions under unclear circumstances. The EBV lifecycle is characterized by interactions with other viruses or bacteria, which increases the probability of awakening its pathobiont capacity. For instance, EBV infects B cells with the potential to alter the germinal center reaction (GCR)—an adaptive immune structure wherein mutagenic-driven processes take place. HIV- and Plasmodium falciparum-induced B cell hyperactivation also feeds the GCR. These agents, along with the B cell tropic KSHV, converge in the ontogeny of germinal center (GC) or post-GC lymphomas. EBV oral transmission facilitates interactions with local bacteria and HPV, thereby increasing the risk of periodontal diseases and head and neck carcinomas. It is less clear as to how EBV is localized in the stomach, but together with Helicobacter pylori, they are known to be responsible for gastric cancer. Perhaps this mechanism is reminiscent of the local inflammation that attracts different herpesviruses and enhances graft damage and chances of rejection in transplanted patients. In this review, we discussed the existing evidence suggestive of EBV possessing the potential to synergize or cooperate with these agents to trigger or worsen the disease.

Abstract
Pathogen transmission is a key point not only for infection control and public health interventions but also for understanding the selective pressures in pathogen evolution. The “success” of a pathogen lies not in its ability to cause signs and symptoms of illness but in its ability to be shed from the initial hosts, survive between hosts, and then establish infection in a new host. Recent insights have shown the importance of the interaction between the pathogen and both the commensal microbiome and coinfecting pathogens on shedding, environmental survival, and acquisition of infection. Pathogens have evolved in the context of cooperation and competition with other microbes, and the roles of these cooperations and competitions in transmission can inform novel preventative and therapeutic strategies.

Abstract
Background:
Generally, about half of the patients with central nervous system infections cases remain unexplained. Therefore, we aimed to describe which viruses were detected in unselected patients with a suspected central nervous system infection and the first diagnostic workflow in a university hospital laboratory.
Methods:
A comprehensive virus testing in cerebrospinal fluid with an in-house real-time PCR method was employed. Determining how many and which viruses to test was at the full discretion of the treating physician.
Results:
1462 patients were evaluated from 2011 to 2017 and 9 898 viral PCRs were made: 176 subjects (12%) had a positive result. There was great heterogeneity in the frequency of patients tested for each virus, ranging from 97.9% (1431 out of 1462) for herpes simplex virus (HSV) to 1.9% (28 out of 1462) for Parvovirus B19, positive in 1 patient. Enterovirus (EV) was the leading virus detected: the frequency was higher with respect to HSV (5.2% vs 2.4%, p=0.0004), varicella-zoster virus (VZV)(5.2% vs 2.9%, p=0.0052), human herpesvirus-6 (5.2% vs 1.7%, p=0.0014) and human herpesvirus-7 (HHV-7)(5.2% vs 2.5%, p=0.0406). Both VZV (83.5%) and HSV (97.9%) were tested significantly more than EV (68.7%, p<0.0001) and HHV-7 (24.1%, p<0.0001): the latter had a positivity comparable to HSV and it was detected in younger patients (median age 29 years), as for EV (median age 35 years). There was no difference found in the age of positive subjects with respect to negative ones for the other viruses tested.
Conclusion:
EV was the fifth virus frequently included in the diagnostic workflow but the most frequently detected, mostly in subjects aged less 40, as HHV-7 was. Testing these two viruses in all younger patients could reduce the number of unknown etiology.

Abstract
Epstein-Barr Virus (EBV) is associated with the Hodgkin's and Non-Hodgkin's lymphoma (HL and NHL respectively). HIV is a risk factor for EBV infections and previously published data indicate that HIV infected individuals have higher chances of getting EBV infections compared to HIV uninfected individuals. Very limited information is available from India about the the prevalence of EBV in HIV positivity, with or without malignancy. In a recent study (Sinha et al. Current HIV Res 16:1-6, 2018) from All India Institute of Medical Sciences (AIIMS), New Delhi, we have shown that 2% among the HIV-1 infected individuals have malignancies including HL and NHL. To determine the prevalence of EBV among these individuals, clinical specimen obtained from ART clinic of AIIMS were tested for the presence of EBV DNA in plasma samples by quantitative real-time PCR. We have observed high prevalence of EBV (30%) among the 92 specimen tested. Prevalence is higher in patients with malignancy (37%) compared to those without maliganancy (27%). No correlation was observed with the CD4 counts or HIV viral load with EBV positivity.

Abstract
As a result of the extension of life span produced by increasing access to combined antiretroviral therapy, people living with HIV/AIDS (PLWH) face new challenges from comorbidities. Although advances in medical care for HIV infection have dramatically reduced opportunistic infections and AIDS-defining cancers, some non-AIDS-defining cancers (NADC) and specific oral diseases such as periodontitis and salivary gland disease are now more prevalent. Cancer prevention is, therefore, a priority issue in care of PLWH, stressing both restoration of immune function and reduction of non-HIV cancer risk factors (tobacco in all its forms; areca nut; heavy alcohol consumption; diets lacking antioxidant vitamins and minerals; and oncogenic virus infections) through specific interventions, especially tobacco and areca nut cessation and alcohol moderation. Detection of oral high-risk human papillomaviruses (HR-HPV) and the universal preventive HPV vaccination among PLWH should be promoted to reduce the malignancy burden, along with routine oral examinations which remain the cheapest, most reliable, most reproducible, and non-invasive tool to identify suspicious lesions. Also, considerations of oral inflammation and periodontal health are important to replication and gene expression of viruses in the mouth. Considering that a key risk factor for this scenario is the presence of oncogenic virus infection such as several members of the human herpesvirus and human papillomavirus families, here we analyze the variables involved in the seeming increase in comorbidities in PLWH.

Abstract
Allogenic stem-cell therapies benefit patients in the treatment of multiple diseases; however, the side effects of stem-cell therapies (SCT) derived from the concomitant use of immune suppression agents often include triggering infection diseases. Thus, analysis is required to improve the detection of pathogen infections in SCT. We develop a polymerase chain reaction (PCR)-based methodology for the qualitative real-time DNA detection of cytomegalovirus (CMV), with reference to herpes simplex virus types 1 (HSVI), Epstein–Barr virus (EBV), and varicella-zoster virus (VZV) in blood, urine, solid tissues, and cerebrospinal fluid. This real-time PCR of 96-well plate format provides a rapid framework as required by the Food and Drug Administration (FDA) for clinical settings, including the processing of specimens, reagent handling, special safety precautions, quality control criteria and analytical accuracy, precisely reportable range (analyst measurement range), reference range, limit of detection (LOD), analytical specificity established by interference study, and analyte stability. Specifically, we determined the reportable range (analyst measurement range) with the following criteria: CMV copies ≥200 copies/mL; report copy/mL value; CMV copies ≤199 copies/mL; report detected but below quantitative range; CMV copies = 0 with report <200 copies/mL. That is, with reference range, copy numbers (CN) per milliliter (mL) of the LOD were determined by standard curves that correlated Ct value and calibrated standard DNA panels. The three repeats determined that the measuring range was 1E2~1E6 copies/mL. The standard curves show the slopes were within the range −2.99 to −3.65 with R2 ≥ 0.98. High copy (HC) controls were within 0.17–0.18 log differences of DNA copy numbers; (2) low copy (LC) controls were within 0.17–0.18 log differences; (3) LOD was within 0.14–0.15 log differences. As such, we set up a fast, simple, inexpensive, sensitive, and reliable molecular approach for the qualitative detection of CMV pathogens. Conclusion: This real-time PCR of the 96-well plate format provides a rapid framework as required by the FDA for clinical settings.

Abstract
Background Few studies focused on longitudinal modifications over time of high-risk HPV (HR-HPV) at anal and oral sites in HIV+ men who have sex with men (MSM). Methods We described patterns and longitudinal changes of HR-HPV detection and the prevalence of HR-HPV covered by the nonavalent HPV vaccine (vax-HPV) at oral and anal sites in 165 HIV+ MSM followed in an Italian hospital. The samples were collected at baseline and after 24 months (follow-up). The presence of HPV was investigated with Inno-LiPA HPV Genotyping Extra II. Results Median age was 44 years (IQR 36–53), median CD4+ cell count at nadir was 312 cells/mm3 (IQR 187–450). A total of 120 subjects (72.7%) were receiving successful antiretroviral therapy (ART). At baseline and follow-up, the frequency of HR-HPV was significantly higher in the anal site (65.4% vs 9.4 and 62.4% vs 6.8%, respectively). Only 2.9% of subjects were persistently HR-HPV negative at both sites. All oral HR-HPV were single at baseline vs 54.6% at baseline at the anal site (p = 0.005), and all oral HR-HPV were single at follow-up vs 54.4% at anal site at follow-up (p = 0.002). The lowest rate of concordance between the oral and anal results was found for HR-HPV detection; almost all HR-HPV positive results at both anal and oral sites had different HR-HPV.The most frequent HR-HPV in anal swabs at baseline and follow-up were HPV-16 and HPV-52.At follow-up at anal site, 37.5% of patients had different HR-HPV genotypes respect to baseline, 28.8% of subjects with 1 HR-HPV at baseline had an increased number of HR-HPV, and patients on ART showed a lower frequency of confirmed anal HR-HPV detection than untreated patients (p = 0.03) over time. Additionally,54.6 and 50.5% of patients had only HR-vax-HPV at anal site at baseline and follow-up, respectively; 15.2% had only HR-vax-HPV at baseline and follow-up. Conclusions We believe that it is important testing multiple sites over time in HIV-positive MSM. ART seems to protect men from anal HR-HPV confirmed detection. Vaccination programmes could reduce the number of HR-HPV genotypes at anal site and the risk of the first HR-HPV acquisition at the oral site.
