Vibrio vulnificus, a zoonotic bacterial pathogen was isolated for the first time from kidneys of black scorpionfish Scorpaena porcus collected from the south Mediterranean basin (western coast of Tripoli, Libya) during the early summer of 2013. Fish exhibited typical signs of Vibriosis with furuncle like lesions, skin hemorrhages, fin rot and congested spleen. The abdominal cavity, liver, intestinal wall, and gonads were suffering from mild larval nematode infection. Interestingly, a huge portion of the kidney tissue was replaced with the anisakids nematode Anisakis pegreffi. This is considered the first report ofV. vulnificus / A. pegreffi in the Mediterranean black scorpionfish. The identities of the retrieved V. vulnificus isolates were confirmed using morpho-chemical and molecular tools. The research lead us to conclude that the deteriorated nature of the sewage polluted seawater at the western coast of Tripoli could have played a detrimental role in facilitating the invasion with the two diverse etiological agents (V. vulnificus and A.pegreffi) . We also hypothesize that V. vulnificus was lodged within nematode worms or at one of its life stages before invading fish intestine with consequent spread into other internal organs during its visceral larval migration stage.

Adhesion and colonization of high (2 × 108 CFU) and low doses (2 × 102 CFU) ofSalmonella enteritidis (phage type 4) was determined in the ceca collected 6 h-4 weeks after inoculation (pi), of 1-d-old White Plymouth Rock orally-inoculated chickens.S. enteritidis was associated with the epithelial surface of the villi in the low-dose group 18 h-7 d pi, the penetration in the cecal lamina propria was observed on day 1 and 10 pi. In the high-dose group, adhesion and colonization was observed in all birds killed 6 h-14 d pi; penetration of the bacteria into the cecal lamina propria was seen 1–21 d pi. Large numbers of macrophage-like cells containingS. enteritidis were observed in the cecal lamina propria on days 3–21 pi. Colonization and migration byS. enteritidis in the intestinal tract of chickens was shown to be dose dependent.
