Prevalence of Infection of Canine Distemper Virus, Feline Immunodeficiency Virus, and Feline Leukemia Virus in Wild Ecuadorian Ocelots; Efficacy of Their Diagnosis, and Recovery from Infection.

This retrospective study provides an analysis of the prevalence and detectability of canine distemper virus (CDV), feline leukemia virus (FeLV), and feline immunodeficiency virus (FIV) in ocelots (Leopardus pardalis) sheltered in a wild animal recovery center in Guayaquil, Ecuador. Blood samples of 19 rescued ocelots from 2019-20 were analyzed using FeLV p27 antigen enzyme-linked immunosorbent assays (ELISA) and commercial insulated isothermal reverse transcriptase PCR (iiRT-PCR) kits. Using this PCR we detected positive results for CDV (4/ 17; 23.5%) and FeLV (14/16; 87.5%), but not for FIV (0/8). Three previously positive cases of CDV and two of FeLV showed negative results on retesting 6 mo later. Moreover, a third analysis was conducted and was negative for CDV. Our results suggest that ocelots can recover from the local CDV and FeLV strains. An ELISA for the FeLV p27 antigen showed no capability to detect FeLV in ocelots that were confirmed positive by iiRT-PCR. Regional lineages, viral virulence, and host immune response capabilities should be addressed in further research to inform management and decision making for wildlife conservation.

First description of sarcoptic mange in a wild coati (Nasua narica), in Ecuador, and cooccurrence of canine distemper virus.

We present a case of Sarcoptes and canine distemper virus (CDV) infection in a white-nosed coati (Nasua narica) that was trapped in the dry tropical forest of Cerro Blanco reserve, located in the coastal region of Ecuador. Sarcoptic mange is a highly contagious and zoonotic disease with worldwide distribution that causes epidemics. Mange is produced by Sarcoptes mites that causes severe epidermal damage. Secondary infections and physiological constrictions without treatment can lead to death of the host. In addition, cooccurrence of canine distemper virus was detected via iiRT-PCR from serum samples. Physical analyses showed that 90% of the skin was affected by severe alopecia due to the sarcoptic mange infection. The presence of mites and histopathological analyses confirmed the diagnosis of infection. This coati was taken to a veterinary clinic and was fed every day, but it died after four days. This is the first report of sarcoptic mange and the first report of CDV in white-nosed coatis in South America. Further studies are needed in this region, to seek out other suspected cases, given the high capacity for disease transmission. Preventive actions to avoid epidemic and zoonotic episodes are needed.

Effects of the Pedernales Earthquake on Ecuador's Health Care System.

OBJECTIVE: This study analyzes the effects of the Pedernales earthquake (April 2016) on Ecuador's health care system. METHODS: A research was carried out in Chone Canton, which combined documentary, quantitative, and qualitative techniques. Epidemiological and service production information taken from official documents was analyzed systematically. In-depth interviews and surveys were conducted with health care program directors and technicians from the Health Centres of the Ministry of Public Health and the users. RESULTS: Deficiencies in the health care system were already observed in Chone Canton prior to the earthquake mainly due to the lack of doctors, nurses, and hospital beds. According to the interviewees, the health district was not prepared for an emergency like the earthquake. Some buildings fell after the earthquake, and Chone Hospital was disabled. These problems coupled with preventive action failures at the community level led to an increase in diseases after the earthquake. CONCLUSIONS: The shortage of personnel and physical infrastructure, weaknesses in primary health care in the Ecuadorian health system, the lack of preparation, and limited availability of information on health indicators were the causes of the sharp increase in pre-existing diseases in the area, and of new epidemic outbreaks after the earthquake.

Evaluation of COVID-19 Surveillance Strategy in Ecuador.

OBJECTIVES: Evaluate the relevance of the coronavirus disease 2019 (COVID-19) positive case detection policy or model implemented by the Ministry of Public Health (MPH) of Ecuador and to compare it with the experiences of other countries. METHODS: Data contained the daily reports publicized by the MPH. The formulations were carried out under the Conditioned Probability modality applying Bayes' Theorem. All the COVID-19 tests applied in relation to the confirmed cases per million inhabitants were considered to obtain their level of positivity, and compared with the experience of Iceland and South Korea. RESULTS: The probability of detecting positive cases of COVID-19 in Ecuador was higher than Iceland and South Korea, because the diagnostic tests were aimed at symptomatic patients, without identifying asymptomatic or mild symptomatic, who play an important role in the transmission of the disease. In addition, many symptomatic patients were examined but will remain undiagnosed due to the unavailability of tests and the low quality of many of them. CONCLUSIONS: The daily reports on the behavior of the COVID-19 issued by the Ecuadorian government do not adequately represent the growth in the number of those infected each day, nor the actual behavior of the epidemic, affecting possible control measures.

Resumo Apresentamos um caso de Sarcoptes e infecção pelo vírus da cinomose canina (CDV) em um quati-do-nariz-branco (Nasua narica) que ficou preso na floresta tropical seca da reserva de Cerro Blanco, localizada na região costeira do Equador. A sarna sarcóptica é uma doença altamente contagiosa e zoonótica de distribuição mundial que causa epidemias. A sarna é produzida por ácaro do gênero Sarcoptes que causa graves danos epidérmicos. Infecções secundárias e constrições fisiológicas sem tratamento podem levar à morte do organismo. Além disso, a coocorrência do vírus da cinomose canina foi detectada, via iiRT-PCR, a partir de amostras de soro. As análises físicas mostraram que 90% da pele estava afetada por alopecia severa devido à infecção pelo ácaro da sarna sarcóptica. A presença de ácaros e análises histopatológicas confirmaram o diagnóstico de infecção. Esse quati foi levado a uma clínica veterinária e foi alimentado todos os dias, mas morreu após quatro dias. Esse é o primeiro relato de sarna sarcóptica e o primeiro relato de CDV em quatis-de-nariz-branco na América do Sul. São necessários mais estudos nessa região, para buscar outros casos suspeitos, dada a alta capacidade de transmissão da doença. Ações preventivas para evitar episódios epidêmicos e zoonóticos, são necessárias.

Oral supplementation with omega-3 fatty acids and inflammation markers in patients with chronic kidney disease in hemodialysis.

Chronic kidney disease (CKD) is an increasingly common public health problem that increases the risk of death because of cardiovascular complications by 2-3 times compared with the general population. This research concerns a prospective, randomized, double-blind study in patients with CKD undergoing hemodialysis. The participants were assigned to 1 of 2 groups: the study group (group A; 46 patients) received 4 capsules (2.4 g) of omega-3 fatty acids daily during the 12-week intervention, while patients in the control group (group B; 47 patients) received 4 capsules of paraffin oil. The patients' general characteristics, nutritional indicators, renal disease markers and inflammatory markers (C-reactive protein, interleukin (IL)-6, IL-10, and tumour necrosis factor alpha (TNF-α)) were evaluated. No differences were found between the general characteristics of the patients (P < 0.05), and no differences were shown in the nutritional indicators and markers of kidney disease (P < 0.05). Patients in group A showed significant decreases in levels of C-reactive protein, IL-6, TNF-α, and the IL-10/IL-6 ratio after 12 weeks of supplementation (P < 0.05). Patients in group B did not show any significant changes in concentrations of inflammatory markers during the intervention (P < 0.05). In conclusion, oral supplementation with omega-3 fatty acids produces a significant decrease in the concentrations of inflammation markers in patients with chronic kidney disease on hemodialysis. Novelty Oral supplementation with omega-3 fatty acids produced significant decreases in the concentrations of inflammation markers. This supplementation could be given to patients with uremic syndrome and coronary heart disease to reduce cardiovascular risk.
