Aflatoxin B1 (AFB1), which is a toxic compound produced by the filamentous fungus Aspergillus sp., is highly carcinogenic, damages vital organs, and may cause death. Prevention of aflatoxin poisoning through proper food storage and physical treatment is an added cost, thus there is a need to identify alternative methods including treatment with probiotic bacteria. We evaluated the effect of Lactobacillus bulgaricus on activating immune cells in mice exposed to Aflatoxin B1. The study used a post-test control design consisting of five treatment groups including a negative control, positive control, and T1, T2, and T3 groups treated with lactic acid bacteria at doses of 105 colony forming unit (CFU)/ml, 107 CFU/ml, and 109 CFU/ml, respectively, administered on days 7-28 and AFB1 at a dose of 0.2 mg/ kg bw orally on days 15-28. The relative number of lymphocytes consisting of CD11c+transforming growth factorbeta (TGF-β)+, CD4+CD8+, and B220+IgG+, was measured using flow cytometry. The data were analyzed using a one-way analysis of variance test. The results indicated that L. bulgaricus bacteria increased the relative number of CD11c+TGF-β+, B220+IgG+, and CD4+CD8+ cells in mice exposed to the mycotoxin. Lactobacillus bulgaricus may function as an immunostimulator against mycotoxins by inducing the humoral and cellular immune response.

Salmonellosis that attacks poultry, caused by Salmonella enteritidis is a cause of food borne disease in zoonotic humans. Treatment of this disease uses antibiotics but if used irrationally it can result in the emergence of multi-drug resistant bacteria. At present many treatments use herbs which are considered to reduce the negative effects of antibiotics and are environmentally friendly, one of which is coffee. Green coffee is considered to have many active ingredients such as chlorogenic acid (CGA), alkaloids, tannin, polyphenols and polysaccharides which are useful as antimicrobial, anti-inflammatory and enhances the body's immune system. The study used 60 heads ISA Brown day-old chicks (layer strain) chickens artificially infected with S. enteritidis bacteria with concentration of 10 8 CFU/ml, consisting of negative controls (healthy chickens, without coffee, positive control (chickens were given), T1, T2 and T3 was given different doses of coffee extract with 500 mg/kg BW, 1000 mg/kg BW and 1500 mg kg BW, respectively. The treatments with coffee extracts were given on days 3-15, then infected with 0.5 ml bacteria on day 16 and 60 chickens were necropsied at day 18 for histopathology. Data on relative levels of CD8 Tc cells were calculated using the flowcytometer test and analyzed quantitatively using the One Way ANOVA with a confidence level of 95% while the jejunum histopathology was observed using a microscopy and analyzed descriptively. Results showed that Robusta coffee extract from Lampung can act as an antibacterial by increasing CD8 + T cells and repairing jejunum histopathology.

Escherichia coli are normal flora in the digestive tract of animals and humans but can be opportunistic under certain conditions. Apart from normal flora, there are also pathogenic strains of the E. coli bacteria that can cause disease in the hospes. The disease that can be caused by E. coli bacteria is colibacillosis which often occurs in poultry. One of the clinical symptoms that appear in chickens suffering from colibasillosis is diarrhea which can arise due to enteritis. This study aims to identify the incidence of colibacillosis and antibiotic resistance of E. coli bacteria in Free-range Chicken. Clinical symptoms showed that the animal looked weak, had diarrhea, and had feces around the cloaca. The necropsy results showed the presence of hemorrhage in the duodenum and caecum. Samples of organ swabs that experienced hemorrhage were then tested for isolation and identification of E.coli bacteria and antibiotic resistance using the Kirby-Bauer method for five types of antibiotics, penicillin, bacitracin, gentamicin, cefadroxil, and ciprofloxacin. The test results showed that the Free-range Chicken had colibacillosis. The E. coli bacteria that cause colibacillosis were resistant to penicillin and bacitracin antibiotics, intermediates to cefadroxil, and sensitive to ciprofloxacin and gentamicin.

Perak Nitrat (AgNO3) sering dimanfaatkan di bidang kesehatan sebagai bahan antimikroba. Efek pada organisme yang terpapar perak nitrat dapat mengakibatkan adanya akumulasi toksik pada hepar. Penelitian ini bertujuan mengetahui dampak toksisitas perak nitrat terhadap kadar SGPT dan SGOT pada mencit Balb-c. Hewan coba yang digunakan pada penelitian ini berjumlah 20 ekor mencit Balb-c dengan berat badan 25-30  gram dan umur 2-3 bulan serta masa pemberian perlakuan selama 14 hari. Perlakuan yang diberikan terdiri dari kelompok K- (tanpa induksi), P1 (100 µg/ml), P2 (200 µg/ml), P3 (300 µg/ml), P4 (400 µg/ml). Kadar SGPT dan SGOT diamati dengan menggunakan metode spektrofotometri. Data dianalisa menggunakan uji One Way ANOVA dengan tingkat kepercayaan 95%. Hasil dan kesimpulan menunjukkan induksi larutan perak nitrat pada mencit Balb-c dengan dosis P4 (400 µg/ml) dan volume induksi 0.5 ml dapat menyebabkan toksisitas pada mencit yang ditandai dengan peningkatan kadar SGPT dan SGOT.

Background: Foodborne diseases are caused by acquired pathogenic bacteria such as Salmonella enteritidis. It causes an intestinal imbalance and the microbial toxins found in the gastrointestinal tract induce symptoms such as diarrhea. Coffee contains active ingredients such as antioxidants and is used as an anti-inflammatory agent by reducing pro-inflammatory cytokine levels in the body. Aim: The purpose of this study was to determine the interaction between Lampung’s robusta coffee and tissue damage in chickens infected by S. enteritidis. Methods: This study used first-day-old Isa brown layer chickens (n = 60), which were divided into five treatment groups. The negative control group consisted of healthy and normal chickens, whereas the positive control group consisted of chickens infected with S. enteritidis bacteria at a concentration of 108 CFU/ml. Groups T1, T2, and T3 were given coffee extract with doses of 500 mg/kg BW (low dose), 1,000 mg/kg BW (moderate dose), and 1,500 mg/kg BW (high dose), respectively, and then infected with S. enteritidis bacteria at a concentration of 108 CFU/ml. The coffee extract and bacteria were given orally via a feeding tube at a volume of 0.5 ml per chick. The extract was given for 14 days (from day 3 to day 16), and the bacteria were given on days 16 and 17. On day 18, the chickens were necropsied. The malondialdehyde (MDA) level was analyzed using one-way analysis of variance test with the GLM procedure (<0.05), while the tissue histopath was analyzed using a descriptive qualitative study to examine the ileal damage Results: The results showed that the MDA levels (nmol/l) decreased in treatment groups T1, T2, and T3 compared to the positive control. On the contrary, we found improvements in the ileum histopathology of group T1 and T2 in the form of normal and regular intestinal epithelium arrangement of the ileum, long intestinal villi, and decreased total leukocytes. Conclusion: Green coffee robusta has the potential to increase antioxidants and reduce inflammation in the small intestine of chickens infected with S. enteritidis.
