Thus, this study aimed to compare the microbiological quality of illegal and inspected salami sold in the state of São Paulo, Brazil. For this purpose, 80 salami samples (40 illegal and 40 inspected) were purchased and their microbiological quality was assessed according to the protocol established by the Brazilian Ministry of Health. All samples were considered as acceptable for consumption according to the Brazilian law. However, the samples of illegal salami were significantly higher contaminated with bacteria belonging to the genus Staphylococcus (p = 0.002) and had a higher trend to be contaminated with total coliforms (p = 0.08) and thermotolerant ones (p = 0.07) compared to inspected salami. Salmonella spp. and coagulase-positive Staphylococcus were not detected. In conclusion, although all samples were considered as safe for consumption, illegal salami had a worse microbiological quality when compared to inspected ones.","PeriodicalId":30679,"journal":{"name":"Arquivos do Instituto Biologico","volume":"105 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67201473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In general, control practices that aim to control these pathogens have not been regularly adopted in Brazil. The objectives of the present study were to evaluate the occurrence of phytonematodes in dry bean fields in Paraná and São Paulo states and estimate the pathogenicity of Pratylenchus brachyurus to dry bean in glasshouse experiments. Root and soil were sampled for nematode extraction, identification and estimation of population density. Four glasshouse experiments with different initial population densities were carried out to evaluate the effect of P. brachyurus on the growth of dry bean plants. Six species of phytonematodes were detected, namely Helicotylenchus dihystera , P. brachyurus , Pratylenchus crenatus , Meloidogyne javanica , Meloidogyne incognita and Rotylenchulus sp. The spiral nematode H. dihystera was found in all samples and was the most abundant species in both states. The lesion nematode P. brachyurus was also frequent, reaching 94% in Paraná and 100% in São Paulo. The root-knot nematodes and Rotylenchulus sp. were reported only in São Paulo fields (45% and 18% frequency, respectively), and P. crenatus only in Paraná (12%). The most abundant nematode in the soil was H. dihystera , and in roots was P. crenatus. It was demonstrated that densities of 6.66 specimens of P. brachyurus per cm 3 of soil provoke visible and measurable root decay. In conclusion, survey data showed low phytonematode densities and pathogenicity tests demonstrated that densities above 6.67 specimens of P. brachyurus per cm 3 of soil cause damage to the dry bean roots. and forty composite samples in (September 2011 in corresponding to late winter in the Southern Hemisphere). An additional survey was conducted from November 2012 to January 2013 (corresponding to mid-spring until mid-summer, in the Southern Hemisphere) in two municipalities of São Paulo state (Itaí and Itapeva), in which 13 composite samples were collected, exclusively to obtain additional specimens of Meloidogyne spp. A composite sample was taken from each field of variable sizes (1 to 86 ha), consisting of ten randomly collected subsamples of roots and soil. Each root subsample was composed of roots from ten (up to 1-month-old) or five (at least 2-months-old) bean plants. All plants were collected at the vegetative phase (V4) or the beginning of the reproductive phase (R6). Soil from each sampled plant’s rhizosphere (0–20 cm depth) constituted a soil subsample. Each of the composite samples of roots and soil was placed separately in plastic bags. In the laboratory, the root system was cut into 2-cm-length pieces and mixed thoroughly. Then, a subsample of 10 g was taken for nematode extraction by blender centrifugal-flotation method (COOLEN; D´HERDE, 1972) with kaolin and sucrose solution (d = 1.15 g∙mL –1 ), using a centrifuge with four 138-cm 3 -tubes (4 cm diameter and 11 cm height) at 1,800 rpm and 580 g.

Several studies are being carried out in order to control the disease, but until now, there is no efficient way to do this. Some management strategies have been investigated including application of chemical and biological products and utilization of resistant cultivars of potato but there are few reports about the impact of pH and irrigation regimes on the disease. The present study aimed to evaluate the effects of these last two factors on the incidence and severity of potato scab caused by S. scabiei , S. acidiscabies , Streptomyces sp., S. caviscabies and S. europaeiscabiei in assays at pH 4.0, 4.5, 5.0, 5.5, 6.5 and 7.5; and irrigation regimes of once a week, alternate days and daily in greenhouse conditions. The experimental design for the pH tests was randomized blocks arranged in a 5x2 factorial scheme, with 5 replications and 3x2 for the irrigation regimes with 5 replications. The pH tests showed significant differences between the treatments and pH 4,0 - 4,5 presented lower incidence and severity of the disease for the most species tested but no significant differences were observed between the irrigation regimes. The soil acidification is considered a classic strategy for management of the disease and the results obtained herein corroborated this hypothesis.","PeriodicalId":30679,"journal":{"name":"Arquivos do Instituto Biologico","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67202446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
