The present study aimed to investigate bacterial quality of tilapia fish (Oreochromis niloticus) and evaluate the hygienic health hazard of fish contaminated with some food borne pathogens. Bacteria were isolated from intestine, gills and flesh of Oreochromis niloticus collected from Lake Manzala during two seasons; winter and summer, 2017. Microbiological studies was applied for all samples as total viable bacteria, total coliform, faecal coliform, faecal streptococcus and examined for the presence of Pseudomonas sp. Results show that total viable bacterial count mean was highest in intestine 222 x 10 4 CFUg-1 in summer. Total coliform count mean was highest in intestine 425 x 103 CFUg-1 in summer. Faecal coliform count mean was highest in gills 90 x 10 2 CFUg-1 in summer. Faecal streptococcus detected in fish organs only in summer. P. aeruginosa count mean was highest in intestine 185 x 10 2 CFUg-1 in summer. Molecular identification of suspected colonies was as DNA extraction, PCR technique using ISSR protocol and sequencing, using the nucleotide sequences of the genes for 16S rRNA revealed different strains of Pseudomonas aeruginosa. All isolates were tested for resistance to 10 groups of antibiotics namely Tetracycline (10μg), Gentamicin (10μg), Ampicillin (10μg), Trimethoprim/Sulphamethoxazole (25μg), Vancomycin (30μg), Erythromycin (15μg), Ciprofloxacin (30μg), Chloramphenicol (30μg), Amoxicillin (10μg) and Rifampicin (5μg) using Kirby-Bauer disc diffusion method. The results showed high frequency of multi-drug resistance to many antibiotics, particularly penicillin, ampicillin and chloramphenicol. Therefore this fish species caught from the Lake Manzala may pose health hazards to human and the whole ecosystem.

“…Melanoides turricula merupakan makrozoobentos yang memiliki kemampuan mengakumulasi logam berat dari lingkungan akuatik melalui mekanisme bioakumulasi dan biomagnifikasi (Galan et al, 2015). Berdasarkan penelitian Orabi & Khalifa (2020), daerah Port Said (saluran Bahr EL-Baqr) Mesir memiliki konsentrasi logam pada siput Melonoides tuberculata dan bergantung dari aktivitas industri yang dibuang ke perairan. M. tuberculata mengalami biokonsentrasi logam berat di jaringannya, sehingga dapat dijadikan sebagai bioindikator pencemaran logam berat pada perairan.…”

“…M. turricula dapat bertahan hidup pada suhu berkisar 18-32°C. M. turricula cenderung aktif pada malam hari dan memakan banyak alga (Orabi & Khalifa, 2020). Habitat dengan dasar perairan berlumpur dan berpasir disukai oleh famili Thiaridae.…”

Kadmium merupakan salah satu komponen penyusun zat pewarna dalam industri batik, bersifat toksik dan sulit terurai. Perairan yang tercemar kadmium dapat berdampak pada biota air. Melanoides turricula merupakan gastropoda yang banyak ditemukan di Sungai Wangan, dan bersifat bioakumulator kuat dalam mengakumulasi logam berat. Penelitian bertujuan untuk menganalisis konsentrasi dan korelasi kadmium pada M. turricula dan air sungai Wangan. Penelitian dilakukan dengan metode survai di Sungai Wangan, Sokaraja. Obyek penelitian yang digunakan yaitu M. turricula dan air Sungai Wangan. Variabel bebas yang diamati yaitu konsentrasi kadmium air Sungai Wangan dan variabel terikat yaitu konsentrasi kadmium dalam tubuh M. turricula. Parameter utama yang diukur adalah konsentrasi kadmium pada tubuh M. turricula dan konsentrasi kadmium air Sungai Wangan, sedangkan parameter pendukung meliputi suhu, pH, dan BOD (Biochemical Oxygen Demand). Pengambilan sampel dilakukan sebanyak 4 kali ulangan selama 4 bulan pada 3 stasiun pengamatan, yang terdiri dari area sebelum dan setelah mendapat masukkan limbah, serta di area pembuangan limbah. Hubungan korelasi kadmium pada M. turricula dan di air Sungai Wangan dianalisis menggunakan Spearman’s Rank Correlation Analysis. Hasil penelitian menujukkan bahwa kadmium di M. turricula maupun air sungai pada area stasiun sebelum mendapat masukkan limbah memiliki konsentrasi kadmium yang terendah sebesar 2,075 µg/g dan 0,750 µg/L. Area stasiun pembuangan limbah memiliki konsentransi kadmium tertinggi pada M. turricula maupun air sungai yaitu sebesar 6,450 µg/g dan 1,050 µg/L, sedangkan konsentransi kadmium air sungai dan M. turricula di area setelah mendapat masukkan limbah sebesar 4,600 µg/g dan 0,875 µg/L. Berdasarkan Spearman’s Rank Correlation Analysis menunjukkan adanya korelasi kuat antara konsentrasi kadmium M. turricula dengan air sungai.

“…In addition, Lymnaea stagnalis was reported to be one of the most sensitive species to a 96 h copper exposure [53], and a good bioindicator of mercury contamination in aquatic ecosystems [63]. A recent study revealed that the BSAF in Melanoides tuberculata was more than two for six metals, resulting in this species being classified as a macro-concentrator for Mn, Fe, Cu, Zn, Cd, and Pb [64].…”

Canada’s oil sands mining activity produces large volumes of oil sands process-affected water (OSPW), and there have been increasing concerns regarding the potential environmental impacts associated with this material. Developing an understanding of the toxicity of OSPW is critical to anticipating and mitigating the potential risks and effects of the oil sands industry on surrounding ecosystems. The composition of OSPW is highly variable and is influenced by a range of factors. While numerous research projects have been conducted on the toxicity of OSPW, much remains unknown about its impact on various biota. Freshwater gastropods (snails and slugs) are an ecologically crucial aquatic group, and members of this taxa have been used as bioindicators in a range of ecological settings. The literature suggests freshwater snails could be used as an indicator of toxicity in monitoring programs associated with oil sands development. This mini-review explores the use of snails as bioindicators in aquatic systems affected by oil sands development, focusing on how snails may respond to potential constituents of concern in systems exposed to OSPW.
