Reação de maracujazeiro amarelo a Meloidogyne Incognita Raça 3

This study concerned the reaction of yellow passion fruit ‘Maguary’ and ‘Afruvec’ to the phytonematode Meloidogyne incognita race 3 in greenhouse conditions. An entirely randomized experimental design with 3 treatments (‘Maguary’, ‘Afruvec’, and tomato cv. ‘Rutgers’) and 4 repetitions was used, each plot consisting of 1 vase containing 1 plant. After 6 months, an evaluation was made of the index of galls and egg mass in the yellow passion fruit varieties and in the tomato cv. ‘Rutgers’. The classification of resistance to the phytonematode was made by criterion of the reproduction factor (RF). ‘Maguary’ presented a zero index of galls and egg mass, while ‘Afruvec’ showed a low index of galls and egg mass in relation to the tomato cv. Rutgers. According to the RF, ‘Maguary’ was characterized as immune to the phytonematode, while ‘Afruvec’ was resistant, and the tomato cv. ‘Rutgers’ was susceptible.

Serum protein profile of hookworm infection in dogs

Hookworms are parasitic nematodes that cause anemia and intestinal infections in dogs, especially with large worm burdens. However, the serum protein profile of this parasitological disease is still poorly understood. The present study was design to evaluate 80 asymptomatic dogs (age; 8 months–2 years) to detect the presence of the hookworm thin-shelled, morulated eggs in faeces using faecal flotation and to evaluate the serum protein fractions determined by means of sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Forty dogs had an elevated quantity of eggs in faeces (+++) (PD) and 40 dogs were healthy (HD). Infected dogs showed significant increases for IgG estimated concentrations (PD 1.79±0.8 g/dL and HD 1.44±0.72 g/dL, p= 0.04), for ceruloplasmin estimated concentrations (PD 19±15 mg/dL and HD 5±3.5 mg/dL, p=0.0001), for alpha 1-acid glycoprotein estimated concentrations (PD 31.4±17.9 mg/dL and HD 13.5±12.1 mg/dL, p=0.0001) and for a non-identified protein of 23 kDa estimated concentrations (PD 641.5±194.9 mg/dL and HD 519.8± 197.9 mg/dL, p=0.007). Dogs with hookworm infection showed significant differences in the serum protein profile when compared to healthy animals.

Macronutrientes em pepino enxertado em áreas com nematoides de galhas

Macronutrients in grafted cucumber in areas with gall nematodes. Grafting is an often recommended technique for cucumber culture in areas infested with gall nematodes. This study aimed to evaluate the content of macronutrients in grafted cucumber in two rootstocks on soil infested with Meloidogyne incognita race 2 or Meloidogyne javanica, since they may decrease the effectiveness of water and nutrient absorption. One evaluated 9 treatments (factorial 3x3: nongrafted hybrid cucumber Tsuyataro, grafted on squash hybrid Shelper or grafted on squash hybrid Excitte Ikki x without inoculation, inoculation with M. incognita or M. javanica), in a randomized blocks design, with 4 replicates and 6 plants per plot. The characteristics evaluated were: macronutrient content at 72 days after transplantation and macronutrient content at the end of the cycle (99 days after transplantation). The nutrient contents evaluated didn’t differ according to the nematode species (with or without inoculation), however, there’re differences with regard to the rootstocks, with higher values of phosphorus and potassium in grafted plants and higher values of magnesium, calcium, and sulfur in nongrafted plants at the end of cycle.
