“…The variation in creatinine and urea levels in this study did not exceed normal limits, which suggests that methenamine was possibly non-toxic to the kidneys. This agrees with the result of Evgenii and Vladimi [28] who reported that methenamine silver complex has no toxic effects on blood parameters of broilers.…”

Microbial resistance in livestock has become a subject of great concern of public and scientific interest. This study was designed to assess the effects of methenamine feeding regime on growth performances of broilers chickens. For this purpose, 120 chicks of Cobb 500 strain, including 60 males and 60 females of 21 days old with an average weight of 639 g and 584 g respectively were used. They were randomly distributed in 60 experimental units of 2 chicks of same sex per cage until 49 days. Methenamine was incorporated in feed (TA), acidified (TEa) and non acidified (TE) water and compared to an antibiotic medicated diet as positive control (T0 + ) and a ration without any supplement as negative control (T0). The main results showed that, regardless of the feeding regime, methenamine significantly (p < 0.05) increased feed inteake, body weight, weight gain and decreased (p < 0.05) feed conversion ratio. Methenamine whatever the feeding regime induced a significant increase in lactic acid bacteria counts compared to coliforms and coccidies counts. Salmonella were absent throughout the trial period. Regardless of sex and feeding regime, hematological parameters were not significantly affected, with the exception of white blood cell and platelet concentration that decreased significantly (p < 0.05) in male broilers. Serum content in ASAT (Aspartate-transferase), ALAT (Alanine-transferase), creatinine, urea and LDLcholesterol decreased significantly (p < 0.05), while HDL-cholesterol increased. Histology of organs was not affected. Feeding methenamine to broiler chickens through drinking water can be used as an alternative to antibiotic

“…Possible prospects for the use of urotropin are based on the following: 1. Urotropin has antimicrobial activity, so adding it to the culture medium can help preserve biomass from microbial contamination [37]; 2. There are reports that urotropine/glutathione can reduce the cytotoxic effect of sulfur mustard on cultured SVK-14 human keratinocytes in vitro [38].…”

One of the ways to preserve the culture of microalgae for a long time is conservation. All modern methods of preservation and long-term storage of microorganism cultures are based on the transfer of cells to a state of anabiosis, in which metabolic processes are either completely or partially stopped. One of the mechanisms that are realized during the transition to the anabiotic state is a change in cell permeability. This can be achieved by modifying the culture medium. Thus, the search for preservatives that contribute to the long-term preservation of biomass is very relevant. The primary condition for the use of any preservative or a new component of the culture medium should be the absence of a toxic effect on the cell culture. Goal of the work: to determine the cytotoxic effect of some preservatives for the cell culture of Chlorella vulgaris GKO strain. The cytotoxicity of ascorbic acid, lactic acid, citric acid, acetic acid, sodium chloride and urotropin was analyzed for the cell culture of Chlorella vulgaris strain GKO. The following parameters were determined: pH of Chlorella vulgaris suspension with preservative; Total number of cells, MM/ml; The ratio of dead cells to the total number of cells,%; Specific growth/death rate; The optical density of the suspension; The difference in the average optical density,%; Cell size (diameter), µm pH of suspension of Chlorella vulgaris with preservative; Total number of cells, MM/ml; The ratio of dead cells to the total number of cells,%; Specific growth/death rate; The optical density of the suspension; The difference in the average optical density,%; Cell size (diameter), µm pH of suspension of Chlorella vulgaris with preservative; Total number of cells, MM/ml; The ratio of dead cells to the total number of cells,%; Specific growth/death rate; The optical density of the suspension; The difference in the average optical density,%; Cell size (diameter), µm
