Quality Characteristics of Pembe Patlıcan; A Local Eggplant (Solanum melongena L.) Genotype from Çanakkale Ezine

pp. 91 - 100   |  DOI: 10.29329/ijiasr.2023.629.1


There are many local eggplant (Solanum melongena L.) genotypes produced by our producers from their own seeds in various regions of our country. These genotypes are an important breeding resource and have been produced for many years due to their unique characteristics such as taste, smell, color and their health benefits. Çanakkale Ezine region has many unique local agricultural products. Evaluating these genotypes in terms of their health effects, some important quality characteristics and external appearance is an important issue for the agricultural development of the region. The 'Pembe Patlıcan' eggplant genotype, grown in significant quantities in the Ezine region, is a local genotype known in the region for its color, taste and nutritional properties. First aim of the study was to determine the Pink Eggplant genotype, which is produced intensively by different producers in Çanakkale Ezine region; in terms of ascorbic acid content, total carotenoid content, total phenolics content, water-soluble dry matter, titratable acidity, color parameters (L, a, b, Hue) and some important flavonoids (luteolin, apigenin, naringin, catechin). Second aim is to contribute to the agriculture of the region by determining the characteristics of this genotype in the samples produced in the region. Third aim is to have preliminary information about the characteristics of this genotype to guide other possible studies on it. It has been observed that the 'Pembe Patlıcan' genotype, in addition to its unique color that evokes red and purple color perceptions, is an eggplant genotype with high levels of ascorbic acid. In terms of flavonoid components, it was determined that the catechin component was the highest and the luteolin component was the lowest.

Acinetobacter baumannii is an aerobic, Gram -negative cocco-bacilli, non-fermentative, non-motile, and non-fastidious organism belonging to the genus Acinetobacter. The A. baumannii has emerged as a worldwide nosocomial pathogen causing about 80% of nosocomial infections comprising ventilator-acquired pneumonia, bacteremia, meningitis, urinary tract infections, skin and soft tissues infections associated with high mortality rate of approximately 63.3%. Although literature shows sufficient information about the drug resistant A. baumannii, there has been inadequate reports on the antibiotic resistance level of this bacterium in the study area.  The aim of this research was to detect Multidrug-resistant A. baumannii isolates among Gram-negative bacteria isolated from Federal Teaching Hospital, Gombe, Nigeria. A total of 1008 clinical samples were collected and cultured on MacConkey agar and Blood agar plates at 37o C for 18-24 hours. Following the incubation period, discrete colonies obtained were subjected to Gram staining. The Gram-negative isolates were identified based on conventional biochemical tests with further use of VITEK 2 COMPACT (BioMérieux, France) for confirmation of A. baumannii amongst the Gram-negative organisms. The results obtained showed that 263 Gram-negative organisms were isolated. A. baumannii accounted for 8.5% prevalence. Most of the A. baumannii isolated were from the male patients (75%) within the age range of 33-48 years. Antibiotic susceptibility test using Kirby Bauer method in accordance with CLSI guidelines was done on 20 A. baumannii isolates. The isolates were more sensitive to levofloxacin (60%), followed by Gentamicin (55%), then Ciprofloxacin and Tetracycline (50%) respectively. High level of resistance to Ceftriaxone (80%), Cefepime (75%), Ceftazidime (65%), Piperacillin-Tazobactam (55%), Ampicillin/Sulbactam (60%), Tigecycline (60%), Meropenem (55%) and Amikacin (60%). This study revealed that 15 (75%) of the A. baumannii were found to be multidrug-resistant. Therefore, antibiotic stewardship is necessary to combat further dissemination of this organism.
