Papillomaviruses are associated with benign and malignant neoplasias of the skin and mucous membranes. The sequence of a novel canine papillomavirus was determined from DNA detected in the oral cavity of a dog. The sequence of the novel virus canine papillomavirus type 13 (CPV13) shares the highest levels of similarity with the Tau papillomaviruses CPV2 and CPV7.

In the process of searching for the recently described small anelloviruses 1 and 2 (SAVs) with the genomic DNA length of 2.2 or 2.6 kb in human sera, we isolated a novel virus with its genomic organization resembling those of torque teno virus (TTV) of 3.8–3.9 kb and torque teno mini virus (TTMV) of 2.8–2.9 kb. The entire genomic sequence of three isolates (MD1-032, MD1-073 and MD2-013), which comprised 3242–3253 bases and exhibited 76–99 % identities with the SAVs within the overlapping sequence, was determined. Although the MD1-032, MD1-073 and MD2-013 isolates differed by 10–28 % from each other over the entire genome, they segregated into the same cluster and were phylogenetically distinguishable from all reported TTVs and TTMVs. These results suggest that SAVs are deletion mutants of the novel virus with intermediate genomic length between those of TTV and TTMV and that the novel virus can be classified into a third group of the genus Anellovirus.

A novel virus was detected in grapevines by Illumina sequencing during the screening of two table grape (Vitis vinifera) accessions, cultivars Black Beet and Nagano Purple, from South Korea. The monopartite circular ssDNA genome sequence was subsequently confirmed by rolling cycle amplification, cloning and Sanger sequencing. The complete viral genomic sequence from both accessions ranged from 2,903 to 2,907 nucleotides in length and contained the conserved nonanucleotide sequence TAATATT↓AC and other sequence features typical of the family Geminiviridae, including two predicted sense and four complementary-sense open reading frames. Phylogenetic analysis placed the novel virus in a unique taxon within the family Geminiviridae. A naturally occurring defective subviral DNA was also discovered. This defective DNA molecule carried a deletion of approximately 46% of the full-length genome. Both the genomic and defective DNA molecules were graft-transmissible although no disease is yet correlated with their occurrence in Vitis spp. The tentative names Grapevine geminivirus A (GGVA) and GGVA defective DNA (GGVA D-DNA) are proposed. PCR assays developed using primers designed in the coat protein gene led to the detection of GGVA in 1.74% of 1,262 vines derived from 15 grapevine cultivars from six countries across three continents.

According to the authors, the prevalence of SOPR diseases is from 3 to 20%.In a study of 1573 residents of southern China in two age groups who use tobacco and alcohol, the incidence of SOPR was higher among men living in rural areas compared to urban residents. Among women aged 35-44 years, the incidence was higher in urban women, and in the 65-77-year-old group in rural women. In the course of studies in Brazil, among 335 patients older than 60 years, 646 diseases of the SOPR were identified. Similar results were obtained in the analysis of SOPR diseases in the Volgograd region of the Russian Federation

Abstract Staphylococcus cohnii (SC), a coagulase-negative bacterium, was first isolated in 1975 from human skin. Early phenotypic analyses led to the delineation of two subspecies (subsp.), Staphylococcus cohnii subsp. cohnii (SCC) and Staphylococcus cohnii subsp. urealyticus (SCU). SCC was considered to be specific to humans whereas SCU apparently demonstrated a wider host range, from lower primates to humans. The type strains ATCC 29974 and ATCC 49330 have been designated for SCC and SCU, respectively. Comparative analysis of 66 complete genome sequences—including a novel SC isolate—revealed unexpected patterns within the SC complex, both in terms of genomic sequence identity and gene content, highlighting the presence of 3 phylogenetically distinct groups. Based on our observations, and on the current guidelines for taxonomic classification for bacterial species, we propose a revision of the SC species complex. We suggest that SCC and SCU should be regarded as two distinct species: SC and SU (Staphylococcus urealyticus), and that two distinct subspecies, SCC and SCB (SC subsp. barensis, represented by the novel strain isolated in Bari) should be recognized within SC. Furthermore, since large scale comparative genomics studies recurrently suggest inconsistencies or conflicts in taxonomic assignments of bacterial species, we believe that the approach proposed here might be considered for more general application.

Despite the enforced lockdown regime in late March 2020 in Russia, the phenomenon of the continued virus spreading highlighted the importance of studies investigating the range of biosocial attributes and spectrum of individual motivations underlying the permanent presence of the substantial level of spatial activity. For this matter, we conducted a set of surveys between March and June 2020 (N = 492). We found that an individual’s health attitude is the most consistent factor explaining mobility differences. However, our data suggested that wariness largely determines adequate health attitudes; hence, a higher level of wariness indirectly reduced individual mobility. Comparative analysis revealed the critical biosocial differences between the two sexes, potentially rooted in the human evolutionary past. Females were predisposed to express more wariness in the face of new environmental risks; therefore, they minimize their mobility and outdoor contacts. In contrast to them, the general level of spatial activity reported by males was significantly higher. Wariness in the males’ sample was less associated with the novel virus threat, but to a great extent, it was predicted by the potential economic losses variable. These findings correspond to the evolutionary predictions of sexual specialization and the division of family roles.

Dryness of the mucous membranes (in mouth, nose, genitals in women) and skin are the most common complaints of patients with Sjogren’s disease — a multisystem immune‑mediated disorder that causes anxiety and concern associated with the difficulties of initial diagnosis. The authors present a clinical case of a patient with primary Sjogren’s syndrome, a large number of symptoms of digestive diseases, complaints of dryness of mucous membranes, in particular the oral cavity. The diagnosis was confirmed by allied specialists such as ophthalmologist, gynecologist, rheumatologist, dentist. Detailed dental examination revealed the main dental complaints (constant dry mouth, galitos, changes in taste), clinical condition (dryness of the red border of the lips, swelling of the oral mucosa, changes in the relief of the gums), decreased secretory activity and significant reduction of unstimulated salivation with a moderate level of stimulated salivation. It is noted that a significant decrease in sialometry (0.01 ml per minute) and functional activity of the small salivary glands (up to 18) confirms the presence of true xerostomia. Micro‑crystallization of saliva revealed disorganization of irregularly shaped structures, as well as a significant number of organic inclusions, which indicates a violation of homeostasis in the oral cavity. Given the results of ultrasound examination of the large salivary glands and the absence of enlargement and swelling of the glands during clinical examination, we can assume that the destructive damage to the glands is not so pronounced, evacuation function of the gland is not reduced, but the amount of secretion is significantly reduced. To provide medical aid to patients with Sjogren’s syndrome, the accessibility of the qualified consultation is important and required, with conduction of comprehensive examinations by allied specialists, including a dentist.

Pemphigus vulgaris (PV) is a chronic autoimmune mucocutaneous disease. In most cases, the initial manifestation occurs in the mouth as multiple ulcerations preceded by blisters that rupture and later spread to other mucous membranes and the skin. Esophageal impairment is rare. We report a case of PV with esophageal involvement in a 53-year-old woman who sought medical care, complaining of diffuse painful lesions in the oral cavity for approximately 1 month, with no improvement with nystatin. Upper digestive endoscopy (UDE) was performed with findings of vesiculobullous lesions in the proximal and middle esophagus, which were biopsied and for which histopathology confirmed PV in the esophageal mucosa. We draw attention to UDE as important for the diagnosis, and it should be indicated in patients with vesiculobullous lesions of the mouth, especially if there are esophageal complaints.

On 31st December 2019, China informed local WHO office of "cases of pneumonia of unknown etiology detected in Wuhan. As of 6th May 2020, there are nearly 3.6 million cases of corona virus infection and approximately 0.25 million deaths worldwide. The real-time data regarding the actual number of cases, as it originates from the epicenter is the key to the estimation of the case fatality rate, hospitalization rates, expected timeline of arrival of contagion, and other epidemiological data. The novel virus has no available literature pertaining to its epidemiological parameters, on which experts can base their estimates and hence the challenge in planning for epidemic management. Bolstering this challenge are the reports alleging under-reporting by Chinese authorities. Alleged toned down numbers could have led to erroneously low estimates contributing to inadequate public health response globally. We conducted a simulation on epidemiological model of COVID-19 to find out expected time off arrival of infections and mortality in different countries and compared this to actual data.
