RESUMO

Pinus eldarica, P. halepensis and P. radiata are important conifer species native to Mediterranean regions that are cultivated in the southwestern United States for landscaping (Phillips and Gladfelter, 1991; Chambel et al., 2013). Among them, Monterey pine (P. radiata) is native to restricted areas of California and Mexico, but it is extensively grown for timber production in other countries, especially in the Southern Hemisphere (Rogers, 2004). From 2018 to 2022, severe dieback and cankers have been detected on more than 30 mature pines of the three species within a 40-ha urban forest in Orange County, Southern California. Symptoms initiate on the lower portion of the canopy and advance into the crown, leading to quick dieback and, in some cases, to tree death. Cross sections of affected branches revealed wedged cankers with irregular, indistinct margins, and cryptic discoloration (i.e., "ghost cankers"). Pycnidia were observed on the surface of each bark scale of branches with advanced infections. Two morphotypes of Botryosphaeriaceae colonies (n = 34 isolates) were recovered consistently from more than 90% of the symptomatic pines. Two isolates per morphotype were grown on pistachio leaf agar (Chen et al., 2014) for 14 days to induce pycnidia formation. Conidia (n = 50) were hyaline, thin-walled and fusoid to ellipsoidal in shape, ranging from 16.1 to 27.9 (22.6) × 5.4 to 8.2 (6.8) µm for the first morphotype and 11.5 to 20.4 (16.3) × 4.8 to 8.6 (6.3) µm for the second morphotype. The rDNA internal transcribed spacer (ITS), beta-tubulin (tub2), and translation elongation factor 1-alpha (tef1-α) partial gene regions were amplified and sequenced using the primers ITS5/ITS4 (White et al., 1990), Bt2a/Bt2b (Glass and Donaldson, 1995), and EF1-728F/EF1-986R (Carbone and Kohn, 1999), respectively. A multi-locus phylogenetic analysis revealed that isolates UCD9433 and UCD10439 clustered with the ex-type strain of Neofusicoccum mediterraneum (CBS:113083), and isolates UCD9161 and UCD9434 grouped with N. parvum (CMW:9081). Sequences were submitted to GenBank (nos. OP535391 to OP535394 for ITS, OP561946 to OP561949 for tef1-α, and OP561950 to OP561953 for tub2). Pathogenicity tests were performed with above-mentioned isolates on 20-mm-diameter healthy branches of mature Monterey pines (n = 10, 14 years old) located in a research field at UC Davis. Isolates were grown for 7 days on potato dextrose agar and inoculated in the internode area by removing a 5-mm-diameter disk of the bark with a sterile cork borer and placing a 5-mm-diameter mycelial plug. Controls were mock-inoculated with sterile agar plugs, and the experiment was performed twice. After three months, inoculations resulted in vascular lesions that ranged from 20.6 to 49.7 (32.7) mm with N. mediterraneum and from 13.5 to 71.0 (33.6) mm with N. parvum, and the same pathogens were reisolated (70 to 100% recovery). Controls remained symptomless and no botryosphaeriaceous colonies were recovered. Both N. mediterraneum and N. parvum are polyphagous pathogens associated with multiple woody plant hosts (Phillips et al., 2013). Previously, only N. parvum has been associated with pine cankers in Iran, however, the pine species was not indicated (Abdollahzadeh et al., 2013). The detection of these pathogens in urban forests raises concerns of potential spillover events to other forest and agricultural hosts in Southern California. To our knowledge, this is the first report of N. mediterraneum and N. parvum causing Pine Ghost Canker on P. eldarica, P. halepensis and P. radiata.

RESUMO

Objective: This article presents the findings of a review of the literature on public resistance to vaccines and the main factors that have influenced their decisions about immunoprevention, with a focus on the COVID-19 pandemic. Methods: We searched the literature using the terms DeCs/MeSH, anti-vaccination movement, vaccination refusal, epidemics, COVID-19, and impacts on health, using the Boolean operators OR and AND in Google Scholar, Medline, Lilacs, and Ibecs. Documents from official sources were also considered. Results: Throughout history, since vaccination began, people have had controversial perceptions of the procedure: some accept what the health authorities recommend, and others allege hidden intentions behind immunization. The COVID-19 vaccine against SARS-CoV-2 has been no exception. Conclusions: Vaccination has been one of the greatest scientific achievements in public health. However, despite its benefits, it has raised fear, uncertainty, and suspicion in the population. For this reason, it is important to increase health education actions in the population-with clear, concise, understandable information that is based on reliable and truthful sources-in order to reduce resistance to vaccination and address preventable diseases.

RESUMO

RESUMEN Objetivo. El presente artículo busca exponer los hallazgos de una revisión de la literatura sobre la resistencia de la población frente a las vacunas y las principales razones que han influido en sus decisiones hacia a la inmunoprevención, con foco en la pandemia de la COVID-19. Métodos. Se realizó una búsqueda en la literatura utilizando los términos DeCs/MeSH, Anti-Vaccination Movement, Vaccination refusal, Epidemics, COVID-19, Impacts on health, relacionados entre ellos por los operadores booleanos OR y AND en Google Scholar, Medline, Lilacs e Ibecs; también se tuvieron en cuenta documentos de fuentes oficiales. Resultados. A lo largo de la historia, desde el inicio de la vacunación, la percepción de las personas hacia este procedimiento ha sido controversial, hay quienes aceptan lo que las autoridades sanitarias recomiendan y quienes alegan intenciones ocultas detrás de la inmunización; la vacuna contra el SARS-CoV-2 causante de la COVID-19 no ha sido la excepción. Conclusiones. La vacunación ha sido uno de los mayores logros científicos en términos de salud pública, un avance que, a pesar de sus beneficios, ha causado miedo, incertidumbre y suspicacias en la población. Por esta razón, resulta importante incrementar las acciones de educación para la salud en la población, con información clara, concisa y comprensible, y sustentada en fuentes confiables y verídicas, con el fin de disminuir la resistencia a la vacunación y evitar las enfermedades prevenibles.

RESUMO

La fiebre chikungunya es una enfermedad tropical transmitida a los humanos mediante la picadura del mosquito Aedes aegypti y Aedes albopictus. Se manifiesta por fiebre alta, cefalea, mialgias y artralgias. Generalmente tiene un comportamiento benigno; sin embargo, se han reportado casos con manifestaciones atípicas y mortales. Es una virosis emergente del siglo XXI que en el Ecuador se convirtió en una epidemia en el año 2014. Reportamos un caso de una paciente de sexo femenino, 52 años de edad, residente en Quito (Ecuador) que presenta dolor abdominal, dolor torácico, artralgias, mialgias y alza térmica. Fue tratada por pancreatitis aguda de origen a determinar; no obstante, por los antecedentes epidemiológicos y el cuadro sintomático sugerente, se solicitó IgM (inmunoglobulina M) para chikungunya que fue positiva. Se la trató mediante hidratación y analgésicos; tuvo una adecuada respuesta sintomática.


Chikungunya fever is a tropical disease transmitted to humans by the mosquito bite Aedes aegypti and Aedes albopictus. It is characterized clinically by causing high fever, headache, myalgias and arthralgias; usually has a benign behavior, but cases with atypical manifestations that produce mortality are reported. It is an emerging virus in the 21st century. We report a case of a 52-year-old female patient living in Quito, Ecuador, with abdominal pain, chest pain, arthralgia, myalgias and fever. It was treated by acute pancreatitis of origin to determine, however by epidemiological antecedents and suggestive clinical, we decided to request IgM for chikungunya which was positive. The patient received treatment with hydration and analgesia, with adequate clinical response
