This study was carried out to evaluate the antibacterial activity of aqueous and organic extracts Thymus vulgaris L. (Lamiaceae). The hexan (HEX), ethanol (ETH) water (WAT) from aerial parts T. exhibited antimicrobial against slow growth mycobacteria – SGM (n = 49) rapid RGM 50) strains isolated diseased ornamental fish. MICAV values HEX, ETH, WAT were found be at 146.50 μg/mL, 728.00 > 800 respectively. 50.77 253.06 most active extract hexane extract. Its chemical composition...

This study was conducted to determine the effects of Echinacea purpurea (EP) root on growth performance and some haematological parameters juvenile common carp (Cyprinus carpio). meal incorporated into diets as follows: no (E-0), 5 g kg−1 diet (E-5), 10 (E-10) 20 (E-20). Triplicate groups fish averaging 9.6 ± 0.5 were hand-fed twice daily for 60 days. At end feeding trial, weight gain (WG), feed conversion ratio (FCR), specific rate (SGR) significantly higher in fed Echinacea-supple­mented...

Abstract Introduction Citrobacter freundii strains, like other representatives of the same genus, are often described as aetiological factors diseases in humans and animals, including farmed ornamental fish. The aim study was isolation identification C. from fish Poland investigation virulence antibiotic resistance among isolates. Material Methods Twenty isolates were isolated swab samples obtained diseased 16 different species Poland. bacteria initially identified to level by...

Vibrio species are common inhabitants of aquatic environments and have been described in connection with fish human diseases. Six were isolated from diseased freshwater ornamental Poland. The strains identified based on morphological biochemical characteristics confirmed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) as V. albensis (n=3) Gymnocephalus cernua, Sander lucioperca, Paracheirodon innesi, Xiphophorus hellerii; mimicus (n=1)...

The aim of this study was to investigate the antimycobacterial activity 39 free terpenes and their in combination with streptomycin. Antimicrobial first evaluated by screening at concentrations from 1.56 400 μg/mL. None these exhibited positive effects against any nontuberculous mycobacteria (NTM) strains tested. However, six (isoeugenol, nerol, (+)-α-terpineol, (1R)-(−)-myrtenol, (+)-terpinen-4-ol, eugenol) were shown enhance streptomycin NTM isolated diseased ornamental fish.

The free-living Gram-negative bacterium Oligotropha carboxidovorans (formerly: Pseudomonas carboxydovorans), isolated from wastewater, is able to live in aerobic and, facultatively, autotrophic conditions, utilizing carbon monoxide or hydrogen as a source of energy. structure O. lipid A, hydrophobic part lipopolysaccharide, was studied using NMR spectroscopy and high-resolution mass spectrometry (MALDI-ToF MS) techniques. It demonstrated that the A backbone composed two d-GlcpN3N residues...

The aim of this study was to investigate the activity thymoquinone (TQ), carvacrol (CAR) and thymol (TYM) against multi-drug resistant nontuberculous mycobacteria (MDR-NTM), alone in combination with berberine (BER). Antimicrobial first evaluated at concentrations from 8 512 μg/mL. Each compounds tested exhibited good (NTM) isolated fish, MIC values 32-128 In study, we have shown for time synergistic efficacy BER CAR, TYM or TQ NTM strains. Thus, these seems be a new approach combating MDR-NTM

A Siamese fighting fish (Betta splendens) showed a whitish, well-demarcated mass on various sites the body and head. Based histopathological examination, multifocal iridophoroma was diagnosed in fish. On H&E-stained slides iridophores contained fine to coarse golden-brown intracytoplasmic pigment granules, which exhibited white-blue birefringence with polarized light. Additionally, Gram-negative bacteria (Aeromonas hydrophila Aeromonas veronii) were found diseased The present report adds...

This study was carried out to evaluate the antibacterial activity of chloroform (CHL) extract Thyme vulgaris L. (Lamiaceae). The CHL from aerial parts T. exhibited antimicrobial against slow growth mycobacteria – SGM (n = 49) and rapid RGM 50) strains isolated diseased ornamental fish. MICAV , MIC90, MIC50 values were found be at 194.00, 400, 200 μg/mL, respectively. 54.59, 100, 50 In conclusion, exhibits non tuberculosis

A male red swordtail Xiphophorus hellerii with a large tumour in its branchial cavity was described this study. The tumour, diagnosed as lymphosarcoma, grew rapidly, pale yellow-white, hard texture, and well-differentiated. It primarily infiltrated the gills showed no visible metastasis. Histopathology of mass revealed dense sheets tight compacted pleomorphic, round neoplastic cells eosinophilic cytoplasm, exhibiting mild to moderate anisocytosis anisokaryosis. Nuclei were generally fine...

ABSTRACT This study presents the first case in Poland of isolation and molecular identification Spironucleus vortens parasite from digestive tract diseased ornamental fish belonging to species discus ( Symphysodon Heckel, 1840). Recently, an increasing percentage submitted for testing Department Biology Fish Diseases, have been observed that show typical symptoms hole‐in‐the‐head disease, therefore it is important accurate information about this disease. In preparation work, two were...
