Background: Few tuberculosis (TB) control programmes in low-income countries have access to culture facilities in their primary care diagnostic centres and this scenario may have worsened with the coronavirus disease 2019 pandemic. Thus the aim was to develop and evaluate a simpler TB test that allows seeding on Löwenstein?Jensen (LJ) medium of several swab-embedded samples decontaminated with sodium hydroxide (NaOH). Methods: A cotton swab containing each sample was decontaminated in NaOH before being dipped into aslightly acidic solution to neutralize the pH in order to allow the culture to develop on LJ medium. Samples (n=543) from suspected or confirmed pulmonary TB were analysed in two phases: standardization (n=167) and evaluation of the study method (n=376). Results: The study method showed sensitivity >95% and specificity >93% using Ogawa?Kudoh (OK) and modified Petroff (MP) as standards and was comparable to MP-LJ (p>0.05) and slightly superior to OK (p=0.03) for sputum culture and more comprehensive than the latter for other pulmonary specimens. Conclusions: This article reports a more comprehensive, simpler and less costly method for diagnosing TB inthe laboratory with fewer economic resources and biosafety equipment. Thus a patent application was filed (BR1020190103841). |

Abstract: This study evaluated the effect of different cutting intensities and years of harvesting on the morphological characteristics and production of fresh (FMP) and dry matter (DMP) of cactus pear cv. Gigante (Opuntia ficus-indica Mill) under conditions of irrigation, high planting density and fertilization, with 12 months of regrowth. The experimental was completely randomized in a factorial design (3 × 2) with 12 replicates. The treatments were three cutting intensities (preserving the mother cladode (PMC), primary cladodes (PPC), or secondary cladodes (PSC)), and two years of harvesting. The soil was classified as Cambisol Haplicum and the irrigation water was classified as C4S1 (EC 5.25 dS.m-1) density of 50,000 plants ha-1. The research evaluated plant height, number of cladodes per plant (NCP), length, width, perimeter and thickness of the cladodes, cladode area (CA), cladode area index (CAI), FMP and DMP. There was no significant interaction between treatments (P > 0.05) for the variables plant height, NCP, CAI and FMP. The variables related to cladode morphology showed a significant interaction (P < 0.05). The treatment PSC resulted in a greater DMP (P < 0.05) with a mean of 27.17 Mg ha-1 yr-1, compared to PPC (18.58 Mg ha-1 yr-1) or PMC (11.78 Mg ha-1 yr-1). The treatment PSC promoted greater NCP and forage productivity at harvest and can be considered as a management practice for the sustainability of cactus pear cv. Gigante under irrigation. The more important morphological characteristics were also influenced by the lower cutting intensities. [Características morfológicas e produtividade da palma forrageira irrigada submetida a diferentes intensidades de corte]. Resumo: A pesquisa objetivou avaliar o efeito de diferentes intensidades de corte e anos de colheita, sobre características morfológicas e produções de matéria verde (PMV) e seca (PMS) da palma forrageira cv. Gigante (Opuntia ficus-indica Mill) sob condições de irrigação, adensamento e adubação, com 12 meses de rebrota. O delineamento experimental foi inteiramente casualizado em esquema fatorial (3 x 2) com 12 repetições. Os tratamentos constaram de três intensidades de corte (preservando o cladódio mãe (PCM), os cladódios primários (PCP) e os secundários (PCS) e dois anos de colheita. Período experimental 24 meses e duas colheitas com intervalos de 12 meses. O solo foi classificado como Cambissolo Háplico e a água de irrigação C4S1 (CE 5,25 dS.m-1) e densidade de 50.000 plantas ha-1. Foram avaliados: altura e número de cladódios por planta (NCP), comprimento, largura, perímetro, espessura e área dos cladódios (AC), índice de área dos cladódios (IAC), PMV e PMS. Não foi observada interação significativa (P>0,05) dos tratamentos para as variáveis altura, NCP, IAC e PMV. Variáveis relacionadas à morfologia dos cladódios apresentaram interação significativa (P<0,05). O tratamento PCS resultou na maior PMS (P<0,05) com produtividade média de 27,2 Mg ha-1 ano-1, quando comparada à PCP (18,6 Mg ha-1 ano-1) ou PCM (11,8 Mg ha-1 ano-1). O tratamento PCS no momento da colheita promoveu maior NCP e maior produtividade de forragem, sendo uma alternativa de manejo com vistas à sustentabilidade da palma cv. Gigante sob irrigação. As características morfológicas mais importantes também foram influenciadas pelas menores intensidades de corte.
