A fluorescent probe based on silicon quantum dots (SiQDs) was developed for the selective and sensitive detection of oxytetracycline (OTC) via the inner filter effect (IFE). The water-soluble fluorescent SiQD was synthesized based on the reaction of 3-Aminopropyltriethoxysilane (APTES) and sodium citrate as precursors by the one-pot hydrothermal process. The strong fluorescence emission of quantum dots (QDs) was obtained at 440 nm when excited at 350 nm and OTC had a broad absorption band between 200 and 400 nm.

Ảnh hưởng của ba loại thuốc kháng sinh (Enrofloxacin, Ciprofloxacin và Oxytetracyclin) lên ấu trùng Hylarana guentheri đã được đánh giá thông qua thử nghiệm độc cấp tính trong phòng thí nghiệm. Tác động được đánh giá bằng cách so sánh tỉ lệ biểu hiện bất thường và tỉ lệ tử vong của nòng nọc ở nhóm đối chứng với nhóm tiếp xúc với kháng sinh. Các biểu hiện bất thường quan sát thấy nhiều nhất ở cả ba kháng sinh là bơi mất thăng bằng, nằm nghiêng dưới đáy bình và chết.

The present study was carried out to evaluate the effect of oxytetracycline (OTC)- dosing at five different concentrations, viz., 0 mg (0X), 80 mg (1X), 240 mg (3X), 400 mg (5X) and 800 mg (10X) kg-1 biomass day-1 for 30 consecutive days on the growth, safety and intestinal histology of Nile tilapia, Oreochromis niloticus (L.) juveniles. The OTC-residues in the edible muscle were detected at scheduled intervals by LCMS/MS. A dose-dependent decline in feed intake, biomass and survival were recorded in OTC-dosed fish. The OTC-residue levels were 0, 204.75±45.75, 318.00±0.00, 778.50±145.

Anaplasma is one of the most rickettsiale diseases in ruminants. Five species including Anaplasma marginale, Anaplasma centrale, Anaplasma bovis, Anaplasma phagocytophilium and Anaplasma ovis are recognized in ruminant animals. Anaplasma causes major economic losses to the livestock owner. Anaplasma is mainly transmitted by mechanical way such as by biting flies, lice and biological by different tick species and fomites in livestock.

A total of 200 fish samples were examined for the presence of extended spectrum βlactamases (ESBL) producing Aeromonas spp. in raw fish samples collected from retail markets of Durg, Raipur, Rajnandgaon and Balod districts of Chhattisgarh state. A total of 70 (35%) fish samples were found contaminated with Aeromonas spp. Among 70 Aeromonas isolates, 16 (22.9%) were phenotypically identified as ESBL producer. Out of these 16 isolates, 11 and 5 were from fresh water and marine fish samples, respectively.

Pus swab collected from wound was processed for bacterial isolation and identification as per standard protocol. Isolate was then subjected to antimicrobial susceptibility test by disc diffusion method using commercial available antibiotics such as ampicillin, amoxycillin, amoxyclav, trimethoprim, chloramphenicol, ciprofloxacin, enrofloxacin, cefepime, cefotaxime, ceftriaxone, ceftriaxone/tazobactum, gentamicin and oxytetracycline.

Metritis and endometritis are the very common postpartum uterine infections that results into infertility in dairy cattle, production loss and economical losses to the farmer. As postpartum uterus favors bacterial growth so it is frequently found in almost of unhygienic environment reared animals. Breaching of birth canal during dystocia, retention of placenta, wet environment during winter season and immunosuppression due to many reasons are the risk factors for the bacteria invasion to uterus.

Antibiotics are freely used as growth promoters and for treatment of animal diseases without adequate knowledge. The indiscriminate use of antibiotics pose a considerable risk due to the presence of residues in milk meant for human consumption. A study was conducted for collection of raw milk samples and its screening for Tetracycline residues using Ultra High Performance Liquid Chromatography (UHPLC) system coupled to Diode Array Detector (DAD). About 175 raw milk samples of cow were randomly collected from roadside milk vendors in sterile containers and then preserved until analysis.

A Reverse phase high-performance liquid chromatographic method (RP-HPLC) for the simultaneous determination of tetracycline, Oxytetracycline and chlortetracycline residues in milk has been developed. The determination of these antimicrobials was carried out using HPLC UV-VIS with a C8 hybrid column elution with a mobile phase composed of solvent A (water: formic acid as 1000:1 v/v) and solvent B (water: acetonitrile: formic acid as 100:900:1). Sample preparation involved protein precipitation followed by solid-phase extraction using a C18 cartridge.
