This investigation studied the innate immune parameters of Macrobrachium malcolmsonii fed diets enriched with 0, 0.01%, 0.1%, or 1.0% Andrographis paniculata extract and infected with Lactococcus garviae. The total hemocyte count did not significantly differ between treatments during the first week but was significantly higher in prawns fed the 0.1% or 1.0% diets during weeks 2 and 4. Phenoloxi...
One of the most important bacterial diseases in aquaculture is Streptococosis/loctococosis. Meanwhile this disease has been known as a zoonosis disease, and then fish vaccination against this disease is important. In this study the specific immunological responses of rainbow trout (Oncorhynchus mykiss) to vaccination with bivalent lactococcal/streptococcal vaccine were investigated. Two hundred...
background and objective: streptococcosis/lactococcosis is the cause of high morbidity and mortality in aquaculture sector and to date a number of species of streptococcus and lactococcus genera including s. iniae, s. agalactiae, s. dysagalactiae, s. parauberis, s. feacalis, l. garvieae and l. lactis have been discriminated as the cause of disease in aquatic animals. despite the use of diagnost...
The antibacterial activities of the essential oil of Eucalyptus globulus (EOEG) was determined against 7 fish pathogenic bacteria (Edwardsiella tarda, Streptococcus iniae, S. parauberis, Lactococcus garviae, Vibrio harveyi, V. ichthyoenteri and Photobacterium damselae) obtained from farmed olive flounder. The inhibitory activity was evaluated by three methods: Disc diffusion method, minimum inh...
letrozole is a synthetic aromatase inhibitor and interfere in the committed step in the synthesis of endogenous estrogens from androgens. also estrogens regulate the immune system in teleost. changes of 17- β- esrtradiol (e 2 ), serum immunoglobulin and lysozyme levels were measured using a method based on the ability of lysozyme to lyse the bacterium micrococcus lysodeikticus , enzyme-linked i...
Background and Objectives: Nowadays, the excessive use of antibiotics has caused bacteria to develop new resistant forms, so that discovering bioactive antimicrobial compounds has been considered by researchers. The aim of this study was to evaluate the antibacterial effect of ethyl acetate extract of red algae (Gelidiella acerosa) on some gram-positive and gram-negative bacteria in laboratory ...
Bu çalışmanın amacı; Citrobacter izolatlarına karşı laktik asit bakterilerinin antimikrobiyal ve antibiyofilm aktivitelerini belirlemektir. çalışmada kullanılan izolatları (C1, C2, C3) BD PhoenixTM otomasyon sistemi ile braakii olarak tanımlanmıştır. Biyofilm oluşumu Kongo kırmızılı agar mikrotitrasyon plak metodu kullanılarak incelenmiştir. Antibiyogram test sonuçlarına göre, tüm izolatlar amf...
Este trabajo concentra la información bibliográfica existente acerca de las bacterias aisladas y/o identificadas a partir peces México. El análisis muestra que el estudio sanidad del país es relativamente reciente, y describe aislamiento varios géneros bacterianos obtenidos tanto clínicamente enfermos como subclínicos, con alta frecuencia oportunistas; asimismo se en última década ha confirmado...
BACKGROUND For some lactic acid bacteria higher biomass production as a result of aerobic respiration has been reported upon supplementation with heme and menaquinone. In this report, we have studied a large number of species among lactic acid bacteria for the existence of this trait. RESULTS Heme- (and menaquinone) stimulated aerobic growth was observed for several species and genera of lact...
15 evaluate the correction term for each triple in the left side of table 1, but for brevity of exposition we will evaluate this term only for a sample of each class (T 2 and T 4).
