The samples of faeces were taken with an average of 13 samples per district and were cultured at the IRED Laboratory in N'Djamena. The strains of Salmonella spp and E. coli isolated were identified by the Enterosystem 18R gallery. Their antibiotic sensitivities were tested against 12 selected antibiotics. The Epi Info 7 ™ software was used to perform the statistical analyses. \u0000Results: For this study, 193 samples of faeces were cultured. However, 24 (12.44%) strains were isolated and identified, including 13 (6.74%) Salmonella spp and 11 (5.70%) Escherichia coli. These strains of Salmonella spp were more sensitive to Imipenem (92.31%). They were more resistant to Clotrimazole (84.62%). For E. coli, the highest sensitivity was observed in Imipenem (76.92%). It was more resistant to Amoxicillin + Clavunalic Acid (AMC) 69.23%. Non-compliance with food hygiene, lack of maintenance of the habitat, non-compliance with prophylactic and sanitary measures were the risk factors most linked to the presence of salmonellosis and E. coli. According to the profile, the resistance of Salmonella spp to antibiotics was more observed in Béraba (23.08%) and that of Escherichia coli in Bédokassa (27.27%). \u0000Conclusion: This study allowed the identification of multidrug resistant Salmonella spp and Escherichia coli in poultry farming households.

Milk and dairy products seem to be highly vulnerable to a wide range of diseases. Therefore, we require processing procedures that both eliminate pathogens and lengthen the useful life of these products. The purpose of this study was to determine how susceptible MRSA isolates were to pasteurization temperatures after being recovered from dairy products. \u0000Materials and Methods: For the purpose of pasteurization, ten MRSA isolates were exposed to both a 63°C LTLT (low temperature, long time) therapy for 30 minutes and a 72°C HTST (high temperature, short time) treatment for 16 seconds. \u0000Results: The findings indicated that all isolates were killed by a pasteurization-like treatment at low temperature for a long time (63°C for 30 minutes), but that particular adaptable isolates could survive a pasteurization-like treatment at high temperature for a short time (72°C for 16 seconds), which may point to a time- and temperature-dependent variation in the thermal tolerance mechanism. \u0000Conclusion: The results showed that all isolates seemed extremely susceptible to damage from heat using LTLT pasteurization-like treatment (63°C for 30 minutes). Nevertheless, a particular number of these isolates succeeded in establishing colonies because they have quorum sensing structures that survive being handled by using heat damage at 72°C for 16 seconds. Pasteurized milk producers should be alerted to the fact that this microorganism has been found in contaminated milk since it compromises the product's safety and diminishes its value to consumers. As a result, it is strongly advised that manufacturers utilize varied temperatures for milk processing in order to remove the contaminating methicillin- and heat-resistant S. aureus (MHRSA).","PeriodicalId":18450,"journal":{"name":"Microbiology Research Journal International","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75469247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 110 cerebrospinal fluids samples (CSF) from suspected children were cultured on different agar media.  \u0000Results: The results showed that 13 samples were positive. Three different bacterial species were identified: Streptococcus pneumoniae (54%=7/13), Hemophilus influenzae b (31%=4/13) and Escherichia coli (15%=2/13). Males predominated, with a sex ratio (M/F) of 1.6. The commune of Ratoma was the most represented with 36%. The most clinical manifestations were fever (54%), vomiting (35%), meningeal stiffness (20%), convulsion (24%) and headache (27%). All the Streptococcus pneumoniae strains were susceptible to levofloxacin and ofloxacin (100%), while 57% of these strains were susceptible to amikacin, 43% to tobramycin as well as to nitrofurantoin and 29% to gentamicin. For Hemophilus influenzae, 75% of the strains were susceptible to gentamicin as well as to tobramycin, ciprofloxacin, levofloxacin, and ofloxacin, while the susceptibility to amikacin was 50%. Finally, all Escherichia coli strains were sensitive to ciprofloxacin, levofloxacin, ofloxacin and nitrofurantoin, while only 50% of these strains were susceptible to amikacin and tobramycin. \u0000Conclusion: This study showed that three bacterial species were associated to meningitis in children, of which Streptococcus pneumoniae was mainly encountered.  Quinolones and aminoglycosides were the most active antibiotic families on these strains studied. The study populations being made up of children and the fact that quinolones are not recommended in this category of patients, aminoglycosides should be chosen for the empirical treatment of children.

Bacteria have proven to be of great benefit in the degradation of petroleum hydrocarbons. This research is aimed at enhanced phytoremediation of crude oil polluted soil using Pseudomonas fluorescens. Soil was collected from oil spill polluted site at B-dere, Rivers State. Six (6) treatments consisting of contaminated soil (CS), uncontaminated soil (US), augmenting organisms Pseudomonas fluorescens (Pse), and phytoremediation grasses (Elbow buffalo grass (Panicum subalbidum) (PAN-G) and Sedge plant Schoenoplectus senegalensis (SCH-G)) were evaluated during a period of 28 days. Total Heterotrophic Bacteria (THB) and Hydrocarbon Utilizing Bacteria (HUB) were monitored. Physicochemical parameters monitored were pH, Temperature, Nitrogen, Phosphorus, Potassium and Total Hydrocarbon Content (THC). Baseline results of physicochemical parameters carried out in the uncontaminated soil were pH, temperature (oC), Moisture content (%), Electrical conductivity (uS/cm), Total Organic Carbon (TOC), Soil Organic Matter, Total Hydrocarbon Content (THC), Nitrogen, Phosphorus and Potassium (mg/kg). The amount of hydrocarbon remediated and percentage bioremediation in the soil after 28 days were: CS+PSE+SCH (3454mg/kg; 85.28%) > CS + BAC + SCH-G (3264mg/kg; 80.59%) > CS +PSE + BAC + SCH-G (3210mg/kg; 79.26%) and CS + SCH-G had the lowest (434mg/kg: 62%). This research revealed that Schoenoplectus senegalensis (sedge plant) is a suitable plant species for phytoremediation of crude oil polluted soil than Panicum subalbidum. Moreso, Schoenoplectus senegalensis (sedge plant) has a higher phytoremediation potential when augmented with Psuedomonas. it is therefore recommended that Schoenoplectus senegalensis (sedge plant) in combination with augmenting organism (Psuedomonas) is best option for remediation of crude oil polluted.","PeriodicalId":18450,"journal":{"name":"Microbiology Research Journal International","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77144104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
