This study was carried out to evaluate the use of Lactobacillus acidophilus as a biocontrol agent against some common fish pathogenic bacteria (Staphylococcus xylosus, Aeromonas hydrophila gr.2 and Streptococcus agalactiae) in African catfish, Clarias gariepinus. Eight treatments were designed inclusive of 10 C. gariepinus juveniles (mean weight 190 g) per tank, each in triplicate. Four groups of fish were fed a diet supplemented with L. acidophilus, comprising about 3.01 × 107 colony‐forming units per gram of diet (the probiotics diet), while the other four groups were fed a diet not supplemented with probiotics (the non‐probiotics diet). In the first group, fish were injected with 1 mL physiological saline and fed the non‐probiotic diet (non‐probiotic control); in the second, third and fourth groups, fish were injected with 1 mL each of S. xylosus, A. hydrophila gr.2 and S. agalactiae, respectively, and were all fed the non‐probiotic diet (designated as non‐probiotic treatments; NPsx, NPah and NPsa respectively). In the fifth group, fish were injected with 1 mL physiological saline but fed the probiotic diet (probiotic control), while fish in the sixth, seventh and eighth groups were each injected with 1 mL of S. xylosus, A. hydrophila gr.2 and S. agalactiae, respectively, and were all fed the probiotic diet (and designated as probiotic treatments; Psx, Pah and Psa respectively). Blood samples were collected for haematology analysis, while samples of the liver and kidney were examined for pathohistology after 7 and 21 days of infection. The results showed that the haematology parameters, packed cell volume, haemoglobin, erythrocyte sedimentation rate, red blood cell, white blood cell, total serum protein, Mg2+, Ca2+, Cl−, glucose, cholesterol and total immunoglobulin concentrations and the pathohistology of the liver and kidney were better in the challenged fish (infected) maintained on the probiotic diet than those in the groups fed the non‐probiotic diet. It is concluded, based on these results, that L. acidophilus is useful as a probiotic agent in C. gariepinus against these pathogenic bacteria (S. xylosus, A. hydrophila gr.2 and S. agalactiae).

“…After infection with Pseudomonas sp., focal necrosis and irregularly shaped nuclei of hepatocytes, eosinophilic granulocytes and erythrocytes were observed. Altinok et al (2007) also stated that Pseudomonas luteola causes a high number of necrotic hepatocytes and enlarged hepatic perisinusoidal areas containing eosinophilic material in the liver of rainbow trout.…”

“…Clinical signs of the disease appear to be the same in all species affected namely petechial hemorrhages of the skin, peritoneum and liver (Wiklund and Bylund 1993). Moreover Altinok et al (2007) also isolated Pseudomonas luteola from rainbow trout, Oncorhynchus mykiss during the outbreak occurred in spring of 2004 and the strain was resistant to most commonly used antibiotics.…”

Bacteria were isolated from Asian Sea bass, Lates calcarifer kept in a farm, on the South-east coast of India. During an outbreak of fin rot, the affected fish had hemorrhages at the base of fins, mouth and skin muscles and faded pigments. Pure colonies were isolated on NA and ZMA from internal organs of the fish and the bacterial morphology was identified as gram-negative rod-shaped bacteria. Based on different biochemical tests and sequence of 16S rDNA, the causative bacteria were identified as Pseudomonas sp. KUMS3. Bacterial cells were isolated from liver and kidney of all artificially infected moribund fish and confirmed as Pseudomonas sp. KUMS3 by morphological and biochemical characteristics. During the experimental infection, the first incidence of dead fish was observed on 2nd day after exposure to Pseudomonas sp. KUMS3 and no fish died after 12 days post exposure and the cumulative percent of mortality was 70. Histological lesions were observed in the spleen, liver and kidney of the infected fish. Pseudomonas sp. KUMS3 could be considered as an opportunistic pathogen, which can survive on the fish surface or in water or in the gut and may cause disease when unfavorable conditions develop.

“…[3][4][5][6] Although most often found in the soil and water sources, P. luteola has been isolated in animals, including turtles, tortoises and fish. 7,8 Clinical isolates show susceptibility to third generation cephalosporins, mezlocillin, imipenem, aminoglycosides, and quinolones. The second pathogen, Escherichia vulneris, is a Gram negative, oxidase negative, indole negative, fermentative motile rod of the family Enterobacteriaceae that has been isolated from animals, drinking water, and humans.…”
