Typhoid fever remains endemic in most developing countries with large scale transmission through contaminated food and drinking water. Since 2000s, animal and their products have been found to be a common food source for Typhoidal infections. A total of 90 blood specimens, 45 samples each were collected from abattoir and non-abattoir workers in Akwa Ibom State and were screened for Salmonella species using standard cultural and serological techniques. The overall prevalence rate was 12 (13.3%). Salmonella species were distributed in all the three senatorial districts of the State. Percentage distribution of Salmonella isolates was 3 (3.3%) for Uyo, 4 (4.4%) for Eket and 5 (5.6%) were isolated from Ikot Ekpene districts. Out of 90 human subjects screened, 12 (13.3%) were positive and 5 (5.6%) were isolated from non-abattoir while 7 (7.7%) were isolated from abattoir workers. In this study, serological significant titre of ≥160 of Typhoid fever cases was confirmed by blood culture. According to sero-grouping and source of sample collection 4.4% S. typhi was isolated from abattoir workers followed by S. paratyphi A (3.3%) while S. typhimurium and S. gallinarum (2.2%) and S. enteritidis (1.1%). Increase prevalence of Salmonella serovars such as S. gallinarium, S. typhi, S. Typhimurium and S. enteritidis with regular consumption of slaughter meat and other product without proper disinfection and appropriate boiling, represent a serious public health risk in Akwa Ibom State. Demographic data obtained in this study showed that majority of the abattoir workers across the three districts were within the ages of 21 to 30 (33%), 39% were none graduate while 30.4% were secondary school leavers. Fever was recorded as the highest clinical signs and symptoms followed by headache, abdominal cramps, diarrhoea and vomiting. Generally, all the isolates identified as Salmonella were tested for their susceptibility to antimicrobial agents. The results showed that Chloramphenicol, Ciprof

Objective:To investigate antibiotics and heavy metals resistance profile of Aeromonas species isolated from Kuala Gula and Kuala Sepetang,***:Isolated Aeromonas species were subjected to 12 antibiotics:penicillin G 10 units,tetracycline 30μg,novobiocin 5μg,nitrofurantoin 100μg,ampicillin 10μg,chloramphenicol 10μg,fluconazole 25μg,gentamicin 10μg,streptomycin 10μg and 25μg,kanamycin 30μg,and vancomycin 30μg and 5 heavy metals:MnSO_(4).H_(2)O,Cr(NO_(3)).9H2O,CuSO_(4),Pb(NO_(3))_(2),HgCl_(2).Results:Results from this study revealed that isolates from the two sources-displayed varied *** from Kuala Sepetang showed 91%,66%,61%,and 52%resistance to vancomycin,Novobiocin,streptomycin and gentamycin while Kuala Gula isolates showed 76%,93%,28%and 14%*** rate of resistance was shown to be against lead(Pb),Chromium(Cr),copper(Cu)and Manganese(Mn)with minimum inhibitory concentration ranging from 2560μg/mL to>5120μg/*** resistance to mercury was observed among isolates from Kuala ***:This study showed that there was widespread of both heavy metals and antibiotics resistance among Aeromonas isolates from the two marine sources with isolates from Kuala Sepetang showing more resistance thereby posing danger to both aquatic animals and human health.
