Abstract: Understanding the amount and distribution of genetic diversity is crucial in breeding programs. This study aimed to assess the variation in qualitative morphological traits among 17 Arabica coffee genotypes. The traits displayed a wide range of phenotypic variation, with the Shannon-Weaver diversity index ranging from 0.22 to 1.12 with a mean of 0.67. The chi-square test revealed significant differences for most of the traits, suggesting dominant phenotypic variation among the evaluated traits. Path coefficient analysis showed a positive direct effect of angle of insertion of primary branches (0.485), canopy diameter (0.264), overall appearance (0.101), and leaf apex shape (0.014) on branching habit. According to the PCA, leaf shape (-0.41) and fruit color (-0.36) from the first PCA and leaf apex shape (-0.43) from the second PCA were the important variables contributing more to the variations. The genotypes were classified into five clusters and the pairwise generalized squared distance among the clusters showed significant divergence between most of the clusters. In conclusion, the present study confirmed the existence of qualitative morphological trait variation among evaluated South Ethiopian Arabica coffee genotypes. It is recommended that the studied genotypes be properly conserved and utilized for the coffee genetic improvement program through selection and hybridization.

Abstract: Background: To better understand the frequency of E. coli and Klebsiella spp. among patients with urinary tract infections at the University of Benin Teaching Hospital, Benin City. Objective: This study aimed to analyze their patterns of antibiotic resistance. Methods: The Kirby-Bauer disk-diffusion method was employed to test the susceptibility of various microbes. Results: E. coli was the most prevalent pathogen in this study's 50 samples, with a prevalence of 64%, followed by Klebsiella spp. with a prevalence of 36%. Escherichia coli isolates were highly susceptible to imipenem (75%) and nitrofurantoin (65.6%), but showed high resistance to cefotaxime (100%), amoxicillin-clavulanate acid (100%), and nalidixic acid (96.9%). Klebsiella spp isolates were highly susceptible to Imipenem (50%) but showed 100% resistance to amoxicillin-clavulanate acid and cefotaxime, respectively. Therefore, these results should form the basis for preliminary decision-making about the best course of treatment for urinary tract infections (UTIs). Conclusion: This study demonstrated that the effectiveness of UTI therapy using available antibiotics is limited due to the increasing prevalence of antibiotic-resistant uropathogens.

Abstract: The objective of this paper review was depending on production and reproductive performance of dual purpose koekoek chicken under different management system in Ethiopia. According to Recent estimates the poultry population in Ethiopia is around 57 million out of which native chickens (none descriptive breeds) represent 78.85%, hybrid chickens 12.02%, and exotic breeds of chicken 9.11%. The total national annual poultry meat and eggs production in Ethiopia is estimated at 72, 300 and 78, 000 metric tons, respectively, and indigenous poultry contributes almost 99% of the national egg and poultry meat production. Dual purpose koekoek chicken is a South African breed of chicken developed in the 1960s at the Potchefstroom Agricultural College in the city of Potchefstroom by Chris Marais. The breed was intended as a dual purpose, free ranging chicken with laying capabilities as well as a large structure for meat production. According different result of study report the reproduction and production performance of this breed under different management system shows significance difference. The production and reproduction performance of koekoek chickens declined compared to intensive management system and farmers` management condition due to poor managements (lack of adequate supplementary feed and poor hygienic conditions). The production performance of koekoek chickens under back yard management condition also hindered due to inadequate veterinary service and lack of multiplying agent (source of stock replacement) and disease outbreak that caused high mortality rate. Average mortality rate during (0-8 weeks) is high and become decrease when they are age of (9-20) weeks. Their survival rate at different management system is high at the age of maturity. (9-20 weeks) Koekoek chickens are well adapted to semi-arid agroecology of mid rift valley area of Ethiopia.
