“…In addition, the V. alginolyticus isolate was also sensitive to gentamicin which interferes with protein synthesis as well. Similar sensitivity results have been reported for M. luteus (Fazlani et al, 2011) and V. alginolyticus isolates (Mustapha et al, 2013). However, the use of such chemotherapeutics in aquacultures must be controlled by government agencies, particularly with respect to dose rates and limitations.…”

Bivalve aquaculture is generally influenced by bacterial pathogens that cause high mortality-related losses in hatcheries. Six bacterial phenotypes had been previously isolated as the most predominant microorganisms in carpet shell clam (Tapes decussates) samples collected from natural beds in representative Egyptian clam fisheries. The main aims of this study were to investigate the nature of the pathogenic strains that significantly affect clam survival and test their susceptibility to commercially available antibiotics. Based on their 16S rRNA sequences and some biochemical features, two potent clam pathogens were emerged; one of which is gram-positive and the other is gram-negative. The former isolate was identified as Micrococcus luteus and the latter as Vibrio alginolyticus. Experimental challenges with the two bacterial pathogens introduced at different initial cell concentrations (2.5 X 10 4-7.5 X 10 4 cfu ml-1) showed markedly diverse clam mortality results. However, the pathogenic interaction of M. luteus with clam survival was generally higher than that of V. alginolyticus. When introduced at a relatively low initial cell density, the infectious records of V. alginolyticus were significantly increased suggesting that the expression of its key virulence factors is mainly triggered as a response to host contact. Antibiotic susceptibility tests suggested chloramphenicol and tetracycline as markedly effective agents that can be used to control the spread of these two bacterial pathogens in aquaculture applications.

The present study aims to evaluate the amount of immunoglobulins A, G, and M in she-camel blood serum in relation with the presence of pathogens in the udder, and to compare the antioxidative capacity and the concentration of zinc, iron, total proteins, and calcium. Milk and blood samples from she-camels from south Jordan were taken; according to milk bacteriological examination, the animals were divided into two groups: (Gm) which contained samples of milk contaminated with bacteria and (Gh) which contained uncontaminated milk samples. Milk and blood were sampled from 30 females and examined for the concentration of immunoglobulins A, G, and M and for the presence of pathogens in milk. Total antioxidant capacity, zinc, iron, total proteins, and calcium concentrations in blood were determined. Milk samples were checked for the presence of pathogens. She-camels for the study were of similar age and productivity in the middle stage of lactation. It was determined that the presence of pathogenic bacteria infecting the udder quarters had considerably influenced the values of immunoglobulins G, A, and M, total antioxidant capacity, and zinc and total protein concentration (p < 0.05) in blood serum; no significant difference in iron and calcium concentration was determined. Subclinical mastitis has a crucial role in increasing the concentration of immunoglobulins in serum; some parameters measured in blood (zinc, total antioxidant capacity, total proteins) could be indicative for the presence of inflammation in she-camels.
