Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of coronavirus disease 2019 (COVID-19), has rapidly spread worldwide. The monitoring of animals has shown that certain species may be susceptible to be infected with the virus. The present study aimed to evaluate the presence of SARS-CoV-2 antibodies by ELISA and virus neutralization (VN) in pets from owners previously confirmed as COVID-19-positive in Argentina. Serum samples of 38 pets (seven cats and 31 dogs) were obtained for SARS-CoV-2 antibody detection. Three out of the seven cats and 14 out of the 31 dogs were positive for SARS-CoV-2 by ELISA, and one cat and six dogs showed the presence of neutralizing antibodies in which the cat and two of the six dogs showed high titers. Another dog from which three serum samples had been obtained within eight months from the diagnosis of its owner showed the presence of antibodies at different times by both ELISA and VN. However, the results showed that the antibodies decreased slightly from the first to the third sample. Our results provide evidence that SARS-CoV-2 infection in pets living with COVID-19-positive humans from Argentina during the outbreak of SARS-CoV-2 can be detected by serology assay.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of coronavirus disease 2019 (COVID-19), has rapidly spread worldwide. Studies of transmission of the virus carried out in animals have suggested that certain animals may be susceptible to infection with SARS-CoV-2. The aim of the present study was to investigate the infection of SARS-CoV-2 in pets (18 cats and 20 dogs) from owners previously confirmed as COVID-19-positive. Oropharyngeal and rectal swabs were taken and analyzed by real-time RT-PCR assays, while blood samples were taken for antibody detection. Of the total pets analyzed, one cat was found reactive to SARS-CoV-2 by real-time RT-PCR of an oropharyngeal and a rectal swab. This cat presented only sneezing as a clinical sign. Serological analysis confirmed the presence of antibodies in the serum sample from this cat, as well as in the serum from another cat non-reactive to real-time RT-PCR. Complete sequence and phylogenetic analysis allowed determining that the SARS-CoV-2 genome belonged to the B.1.499 lineage. This lineage has been reported in different provinces of Argentina, mainly in the Metropolitan Area of Buenos Aires. This study notifies the first detection of the natural infection and molecular analysis of SARS-CoV-2 in a cat from Argentina whose owner where COVID-19-positive. Although there is currently no evidence that cats can spread COVID-19, results suggest that health authorities should test pets with COVID-19-positive owners.

Abstract
La pandemia de la COVID-19 planteó el rápido diseño y aprobación excepcional de diversos métodos de diagnóstico. En la unidad de diagnóstico COVID- 19 de la FCV-UNLP, se realizó el diagnóstico molecular de la presencia de SARS-CoV-2 en 1114 hisopados de pacientes derivados por el Ministerio de Salud de la Provincia de Buenos Aires. Las muestras de ARN fueron purificadas en cabina de seguridad y se analizaron mediante real time RT-PCR con el kit GeneFinder™ para tres targets virales (N, E y RdRp). De 1110 muestras con reacción al control interno, 458 (41,2%) fueron reactivas, 26,9% a tres targets virales, 4,2% a dos y cerca del 10% a uno (principalmente N). El porcentaje de positividad fue similar en el tiempo, aunque la cantidad fue mayor en julio (781 muestras; 315 reactivas) respecto a junio (333 muestras; 143 reactivas). Las muestras de Berisso, Ensenada y La Plata presentaron un porcentaje de positividad significativamente menor al de los demás municipios (27,6% vs. 60,7%). Las muestras de pacientes con tres o más signos relevantes presentaron una mayor positividad (55,6%) y menor reactividad a un único target. Es necesaria la validación interlaboratorios y la estandarización de los métodos para brindar resultados confiables y reproducibles.

Abstract
ΔNp63α is a critical mediator of epithelial development and stem cell function in a variety of tissues including the skin and breast, while overexpression of ΔNp63α acts as an oncogene to drive tumor formation and cancer stem cell properties in squamous cell carcinoma. However, with regards to the prostate, while ΔNp63α is expressed in the basal stem cells of the mature gland, during adenocarcinoma development, its expression is lost and its absence is used to clinically diagnose the malignant state. Surprisingly, here we identify a sub-population of bone metastatic prostate cancer cells in the PC3 cell line that express ΔNp63α. Interestingly, we discovered that ΔNp63α favors adhesion and stem-like growth of these cells in the bone microenvironment. In addition, we show that these properties require expression of the target gene CD82. Together, this work uncovers a population of bone metastatic prostate cancer cells that express ΔNp63α, and provides important information about the mechanisms of bone metastatic colonization. Finally, we identify metastasis-promoting properties for the tetraspanin family member CD82.

Abstract
During austral summers 1999-2000 and 2000-01, two outbreaks of avian cholera occurred in the Hope Bay area (63 degrees 24'S, 56 degrees 59'W), located on the tip of the Antarctic Peninsula. Eighty-six dead birds were found: five kelp gulls (Larus dominicanus), 36 skuas (Stercorarius sp.), and 45 Adelie penguins (Pygoscelis adeliae). The carcasses were studied using clinical, pathological, and microbiological criteria. Water samples from ponds where birds were settled and samples from 90 healthy birds also were analyzed during the second outbreak. Pasteurella multocida isolates were identified by biochemical tests, capsular type, somatic serotype, and susceptibility to nine antibiotics. Molecular subtyping was performed by ApaI and SmaI pulsed-field gel electrophoresis (PFGE) and enterobacterial repetitive intergenic consensus (ERIC-PCR). In February 2000, mortality in skuas was 16% and 2% in kelp gulls. In the 2000-01 breeding season, mortality in south polar skuas was 47%, 24% in brown skuas, 1.4% in kelp gulls, and 0.01% in Adelie penguins. All birds had lesions of avian cholera. In kelp gulls the presentation was chronic, whereas skuas and penguins suffered subacute and acute disease, respectively. Fifty-five isolates recovered from dead birds and one from water were identified as P. multocida gallicida, type A:1. The strains presented a unique molecular pattern by PFGE and ERIC-PCR. A possible hypothesis to explain the origin of the outbreaks was that nonbreeder kelp gulls carried P. multocida gallicida to Hope Bay, and avian cholera was transmitted through water to skuas and penguins. This study reports avian cholera in new bird species, their potential role in the transmission of the disease, and the different responses of these species to the disease.

Abstract
Placental chorioangioma is the most common benign tumor of placenta. The relationship of vascularized chorioangiomas to adverse pregnancy outcome is well recognized. We report 3 cases of placental chorioangioma. Hypervascularization of the lesions in all patients and the immune hydrops with adverse fetal outcome in 2 cases are the complications of our mini-series. Ultrasonography and Doppler ultrasonography findings were useful in establishing the prenatal diagnosis and the prognosis.

Abstract
This study evaluated an indirect immunofluorescence assay (IFA) to detect feline immunodeficiency virus infection (FIV) antibody in a comprehensive epidemiological survey of FIV in Argentina. IFA modified in our laboratory, was compared with two other immunoassays, western blot (WB) and a sandwich immunochromatographic commercial kit (SI), and also with a direct polymerase chain reaction (PCR) method that detects proviral DNA. IFA showed to be a test with high sensitivity and specificity, and could be useful as a diagnostic tool in epidemiological studies. The presence of a low percentage of results with non-specific reactivity in the IFA could be resolved with further testing or use of an alternative method.

Abstract
BACKGROUND In a previous hospital based study, we suggested that undiagnosed coeliac disease has a prevalence, among pregnant women, of 1:80, and is a cause of unfavourable outcome of pregnancy. AIMS In order to confirm or dismiss this hypothesis, which has significant public health implications, we carried out a large population based study on a stratified sample from the whole Campania region. PATIENTS During the period of the study, 5345 women were admitted to the OBS-GYN wards regional network: 5055 (95%) were enrolled in the study. METHODS Antihuman IgA class antitissue transglutaminase (TGASE) antibodies were tested by an ELISA method. Endomysial antibodies (EMA) were investigated on thin sections of human cord blood by an immunofluorescence test. The HLA class II DQA1*0501/DQB1*02 and DQA1*0301/DQB1*0302 haplotypes were assessed using the Eurospital Eu-DQ kit. Duodenal biopsy was not considered feasible by the ethics committee for pregnant women near delivery. RESULTS Fifty one of 5055 patients had confirmed positive results. We added to these 12 women with known coeliac disease, giving a prevalence rate for coeliac disease of 1:80 (exactly the value observed during the first study). Comparing the 51 TGASE positive with 4997 negative women, we did not observe an excess risk of abortion, premature delivery, small birth weight, or intrauterine growth retardation. Anaemia was more frequent in cases than controls. CONCLUSIONS Undiagnosed coeliac disease is frequent among pregnant women (>1%) but is not associated with an unfavourable outcome of pregnancy.

Abstract
Sera from 76 horses from Argentina were examined for antibodies to Sarcocystis neurona, Toxoplasma gondii and Neospora caninum. Antibodies to S. neurona were found in 27 (35.5%) of 76 horses using immunoblots with culture derived merozoites as antigen. Antibodies to T. gondii were found in 10 (13.1%) of 76 horses by using the modified agglutination test with formalin-fixed tachyzoites and mercaptoethanol; titers were 1:25 (two horses), 1:50 (six horses), 1:100 (two horses), and 1:200 (one horse). Antibodies to N. caninum were not found in any of the 76 horses by the use of N. caninum agglutination test. This is the first report of S. neurona infection in horses in Argentina.

Abstract
Matrix (M) and nonstructural (NS) genes of thirteen equine H3N8 and H7N7 influenza viruses were sequenced and analyzed from an evolutionary point of view. The M and NS genes of H3N8 viruses isolated between 1989 and 1993 evolved into two minor branch clusters, including isolates from Europe and the American continent, respectively. It was noteworthy to reveal that the nucleotide sequences of the M and NS genes of an earlier American strain showed highest homology to those of recent European viruses. "Frozen evolution" was observed in the M and NS genes of A/eq/LaPlata/1/88. It was also evident that the NS gene of an H7N7 virus from 1977 was very similar to that of a 1979-H3N8 virus, while the M gene was closest phylogenetically to that of the earliest H7N7 virus isolated in 1956. Furthermore, the M2 protein of A/eq/Newmarket/1/77 virus contained a carboxyl terminal deletion of three amino acids. The evolutionary rates of the M and NS genes of H3N8 equine influenza viruses were estimated to be 5.4 x 10(-4) and 5.1 x 10(-4) substitutions per site per year, respectively, which were slower than those of human viruses.

Abstract
BACKGROUND Patients with HIV infection can have recurrent and persistent oral ulcers, not attributable to known infectious agents. OBJECTIVE Our aim was to evaluate prospectively oral ulcers in patients with HIV infection to determine whether an etiologic agent could be identified. METHODS Sixteen patients with HIV infection who had oral ulcers not attributable to known causes had culture of the base and a biopsy specimen taken from the ulcer. Cultures were obtained for herpes simplex and varicella-zoster viruses, mycobacteria, and fungi. By polymerase chain reaction (PCR) analysis with primer/probe sets for herpes simplex viruses 1 and 2, varicella-zoster virus, cytomegalovirus, human papillomavirus, and Mycobacterium tuberculosis, each biopsy specimen was analyzed for the presence of DNA from these organisms. Specimens were also evaluated histologically. RESULTS Histoplasmosis was detected histologically in one biopsy specimen, candidiasis in a second, and herpetic changes in a third. Viral cultures were positive for herpes simplex virus 1 in four cases and herpes simplex virus 2 in one case. PCR analysis detected DNA for herpes simplex virus 1 in one case and herpes simplex virus 2 in another; DNA from other pathogens was not identified. In the remaining eight patients, hematoxylin-and-eosin staining revealed eosinophilic ulcers in five cases and nonspecific changes in three cases. CONCLUSION The etiologic agent of recurrent or persistent oral ulcers in patients with AIDS and AIDS-related complex was not identified in 50% of patients. PCR analysis was not useful. Herpes simplex virus or other pathogens were not detected in ulcers containing numerous eosinophils.

Abstract
The relation between consumption of alcohol (established by interview), two of its typical markers (gamma-glutamyltransferase activity and mean corpuscular volume), and the composition of fatty acids in plasma cholesterol esters was investigated in an epidemiological study of 1467 actively employed men aged 35-45. In this group of subjects mean consumption of alcohol was 34.6 (SD 25.2) g/day. Palmitoleic acid and oleic acid were positively correlated with consumption of alcohol, gamma-glutamyltransferase activity, and mean corpuscular volume, while linoleic acid was negatively correlated with these variables. When these three fatty acids, gamma-glutamyltransferase activity, mean corpuscular volume, and the fat content of the diet were introduced into a multivariate regression analysis, with consumption of alcohol as the dependent variable, only palmitoleic acid, gamma-glutamyltransferase activity, mean corpuscular volume, and the monounsaturated fat content of the diet remained significant. Palmitoleic acid seems to be an independent correlate of consumption of alcohol and could be useful in epidemiological and clinical studies as a variable of consumption.
