Determining the infectious cause of abortion in cattle is difficult. This case-control study was set up to investigate causes by determining seroprevalence three reproductive pathogens dairy Ecuador and their association with abortion: Brucella abortus, Neospora caninum Coxiella burnetii. Ninety-five blood samples were obtained from cows that had experienced a mid- or late gestation first calf seventy-seven control group same age did not experience problems. No antibodies detected for B....
Knowledge of co-colonization with multiple pneumococcal serotypes is becoming very important in the light both serotype replacement and switching as a result vaccination. Co-colonization has been reported to occur up 30% carriers, especially populations high Streptococcus pneumoniae carriage rates. For determination co-colonization, single colonies nasopharyngeal specimens are serotyped Quellung method, costly method low sensitivity. Here we explore use multiplex PCR identify simultaneous...
Rural communities from Latin America are particularly susceptible to develop serious outbreaks of infectious diseases. Inadequate diagnosis and poor health infrastructure jeopardize proper contact tracing other actions reduce the impact COVID-19 in region. We herein describe preliminary data our ongoing fieldwork massive testing among nonhospitalized rural population Manabi Province coastal region Ecuador. A total 1,479 people six different were tested for SARS-CoV-2 by RT-qPCR following CDC...
Worldwide, the COVID-19 pandemic caused by SARS-CoV-2 has enormously impacted healthcare systems, especially in low and middle-income countries. Coinfections with respiratory pathogens patients may contribute to worse outcomes. This study identified presence of 12 viral coinfections pneumococcal carriers among individuals infection outpatient community settings Ecuador. From January 2020 November 2021, 215 nasopharyngeal nasal swabs were taken from who reported symptoms or had known exposure...
Little attention has been paid to pneumococcal carriage and disease in Amerindians from Latin America. The Warao people, an indigenous population Venezuela, live the delta of Orinoco River geographically isolated communities with difficult access medical care. To obtain insight into theoretical coverage vaccines this population, we investigated colonization, serotype, genotype distribution among children 9 distinct, Delta Amacuro area northeast Venezuela. From April 2004 through January...
The objective of this study was to compare the diagnostic yield Kudoh-Ogawa (K-O) swab method for culturing Mycobacterium tuberculosis from clinical samples with standard Petroff–Lowenstein-Jensen (P-LJ) procedure. A total 2,287 sputum and 685 extrapulmonary specimens were processed both decontamination methods compared M. detection rate, recovery colonies, culture contamination.
Recent research suggests that the microbiota affects susceptibility to both respiratory tract infections (RTIs) and gastrointestinal (GIIs). In order optimize global treatment options, it is important characterize profiles across different niches geographic/socioeconomic areas where RTI GII prevalences are high.We performed 16S sequencing of nasopharyngeal swabs from 209 Venezuelan Amerindian children aged 6 weeks-59 months who were participating in a 13-valent pneumococcal conjugate vaccine...
Soft tissue or skin infections due to nontuberculous mycobacteria (NTM) have been reported frequently and are mostly associated with trauma cosmetic interventions like plastic surgery. However, infection NTM as a result of dental procedure rarely described the lack clinical suspicion clear manifestation makes diagnosis challenging.We report on three patients facial cutaneous sinus tract origin, an respectively Mycobacterium fortuitum, M. abscessus peregrinum. The source was unit waterlines...
Background Although RT-qPCR remains the gold-standard for COVID-19 diagnosis, anti-SARS-CoV-2 serology-based assays have been widely used during 2020 as an alternative individual and mass testing, are currently seroprevalence studies. Objective To study clinical performance of seven commercial serological tests diagnosis available in South America. Methods We conducted a blind evaluation five lateral-flow immunoassays (LFIA) two enzyme-linked immunosorbent (ELISAs) detecting antibodies....
High acute respiratory tract infection (ARTI) rates are observed in indigenous populations. We assessed the role of viral infections and nasopharyngeal bacterial carriage ARTIs Eñepa Amerindians from Venezuela.In 40 children aged 0-10 years with ARTIs, healthy nearest-age sibling controls their mothers presence Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, Moraxella catarrhalis, Mycoplasma Chlamydophila pneumoniae/psittachi 15 viruses was investigated.S. pneumoniae...
Neglected ethnic minorities from underserved rural populations in Latin America are highly vulnerable to coronavirus disease 2019 (COVID-19) due poor health infrastructure and limited access severe acute respiratory syndrome 2 (SARS-CoV-2) diagnosis. Esmeraldas is a mainly province of the Coastal Region Ecuador characterized by high presence Afro-Ecuadorian population living under poverty conditions.We herein present retrospective analysis surveillance SARS-CoV-2 testing community-dwelling...
Abstract Objective To assess risk factors for nasopharyngeal carriage of potential pathogens in geographically isolated Warao Amerindians Venezuela. Methods In this point prevalence survey, swabs were obtained from 1064 Amerindians: 504 children aged 0–4 years, 227 5–10 years and 333 caregivers. Written questionnaires completed to obtain information on demographics environmental factors. Anthropometric measurements performed years. Results Carriage rates Streptococcus pneumoniae ,...
SARS-CoV-2 has spread throughout the world, including remote areas such as those located at high altitudes. There is a debate about role of hypobaric hypoxia on viral transmission and COVID-19 incidence. A descriptive cross-sectional analysis infection load among patients living low (230 m) altitude (3800 in Ecuador was completed. Within these two communities, total number infected people time study 108 cases (40.3%). The incidence proportion 64% while 30.3%. mean from who tested positive...
