Tephritids are the major challenges for fruit and fleshy vegetable growers of the tropics and subtropics. Nepal also incurs huge losses of fruits and vegetables to the tephritids. This study was designed to identify the tephritid flies in Malepatan and Lumle of Gandaki Province. Bucket traps baited with methyl eugenol (ME) in Malepatan, and ME, cue lure (CL) and a mixture of ME and CL (ME+CL) with different releasers; tube, cotton and paper were installed at Lumle in 2020 summer. Three species of the fly (Bactrocera dorsalis, Bactrocera zonata and Bactrocera correcta) were recorded from Malepatan, dominated by B. dorsalis. The B. correcta count was negligible. While in Lumle, B. dorsalis was the most dominant, followed by B. zonata till July, after which, till August, B. tau followed the B. dorsalis. Seven species of the tephritids (B. zonata, B. dorsalis, B. tau, B. diversa, B. scutellaris, B. correcta and B. cucurbitae) were recorded from this region. Among the releasers, paper releaser was found more effective as compared to cotton and tube. However, the lures should be changed in a short interval, by two weeks, to acquire a satisfactory result. This study unveils that the study site already inhabits seven species of fruit flies. So, the monitoring with different cues could be an effective tool for species actuation. Additionally, the paper releasers could be recommended for further use in the traps for monitoring and mass trapping purposes.
The clinical impact of β-lactamase has become a public health problem around the world in terms of increased morbidity and mortality, especially in the child population. This study was aimed at determining the bacteriological profile and detection of β-lactamase producing bacteria isolated from the blood samples of neonates. For this study, a total of 1335 blood samples of neonates admitted in NICU, SCBU, and sepsis-suspected neonates visiting Paropakar Maternity and Women’s Hospital, Thapathali, Kathmandu, Nepal were collected and processed. Blood culture was performed and the identification of bacteria was done by following standard microbiological methods. Antibiotic susceptibility testing was done by using the Kirby Bauer Disk Diffusion method and confirmation of ESBL, MBL, and KPC-producing bacteria was done by Combined Disk Test. The prevalence rate of neonatal sepsis was found to be 17%. K. pneumoniae 116 (50.2%) was the predominant Gram-negative bacteria followed by K. oxytoca 31 (13.4%) whereas S. aureus 39 (16.9%) was the predominant Gram-positive bacteria causing neonatal sepsis. Among 182 Gram-negative bacterial isolates, 69 (37.9%), 22 (12.1%), and 14(31.1%) were found to be ESBL, MBL, and KPC producers respectively. K. oxytoca (54.8%), Enterobacter spp. (25%) and Citrobacter spp. (14.3%) were the predominant ESBL, MBL, and KPC producers respectively. The co-production of ESBL, MBL, and KPC was also found among the 5 Gram-negative bacteria. Colistin, Meropenem, and Imipenem seem to be the choice of the drug against Gram-negative bacteria, whereas Vancomycin and Cefoxitin seem to be the choice of the drug against Gram-positive bacteria. Therefore, to lessen the burden of antibiotic resistance, it is essential to conduct regular antimicrobial susceptibility surveillance, periodic reviews of hospital settings, and early detection of beta-lactamase-producing bacteria.
