The sensitivity of these three rhizobial isolates in response to different types of antibiotics with various concentrations indicated SR 01 to be resistant against most number of antibiotics. Monocrotophos (MCP) is a widely used organophosphorus pesticide which controls a wide spectrum of chewing, sucking and boring insects. Since the statistical calculations and tests required are quite involved, the use of an automatic computer program is desirable. Identity of these Gram's negative rod shaped isolates was established using biochemical as well as 16S rRNA sequencing. ... (Ham).

Monocrotophos is an organophosphorus pesticide. In Germany, during World War II, the compounds were rapidly developed as insecticides, and during the 1950's the commercial use of organophosphates expanded markedly (Eto 1974). The results show that it is highly toxic cholinesterase inhibiting pesticides. Prognosis for Chemical poisoning -- Monocrotophos: Prognosis varies depending on the type and degree of exposure. The pesticide caused increase in the comet tail length with increase in pesticide concentration, implicating genotoxicity in somatic cells. Despite differences in the symptoms, both types of pyrethroids have the same major target site; the sodium channel of nerve membrane, i.e., the channel directly responsible for generating action potentials (Biologic basis of Neuro toxicity., 1992). IC50 value, monocrotophos was found to be highly toxic to lymphocyte culture. Short-term toxicity studies Rats Monocrotophos technical (77.6% pure) was applied to shaven skin of rats (Tif:RAI: 5/sex/dose). The two types of pyrethroids cause somewhat different symptoms of mammalian poisoning. Type II pyrethroids contain a cyano group at the _ carbon position and include newer compounds, such as deltamethrin, cyphenothrin, cypermethrin, and fenvalerate. Comet assay study was used to assess the possibility of monocrotophos induction of DNA damage where the increase in comet tail length relates to the extent of DNA single strand breaks. It is concluded that In vitro assays could give important information of the mechanism of toxicity at low dosages and impact on genetic material of human origin. The results presented here indicate that in vitro assays could be used as indicators of cytotoxicity and genotoxicity of the pesticide. All of the tested concentrations of both insecticides induced a high percentage of metaphases with chromosomal aberrations in cultured mouse spleen cells after 4-h treatment. Studies of the interaction of 50µg mL-1 DNA with the pesticides (from 30 min to 4 hand from 1.0×10-6 to 6.0×10-5molL-1) did not reveal any peaks relating to double helix opening or DNA unwinding. This was further confirmed by SEM analysis. In 2009, it called for India to ban the product because of its extreme toxicity. Cardiotoxicity. Presently, organophosphorus and carbamate pesticides are used as insecticides, herbicides, nematicides, acaricides, fungicides, rodenticides, and bird repellents throughout the world. The discovery that organochlorine pesticides, such as DDT, are highly persistent, bioconcentrate in food chains, and can severely affect whole populations or species of wildlife has led to bans and use restrictions (Stickel 1975). This technique appears to be sensitive and useful for detecting damage and repair in single cells. Monocrotophos, commonly named Azodrin or Nuvacron, is an organophosphate insecticide, which in spite of ban is preferred due to its high efficacy against insect pests.

The acute oral toxicity for rats (LD50) is 23mg/kg (males) and 18 mg/kg (females). The chromosomal analysis was recorded using Medi-Image software technology. This document sets out a classification system to distinguish between the more and the less hazardous forms of selected pesticides based on acute risk to human health (that is the risk of single or multiple exposures over a relatively short period of time). Chromosomal aberrations induced by monocrotophos were determined using karyotyping. Chromosomal aberrations induced by LCT were determined using metaphase plate-spreads of lymphocytes. Broad agreement: comes from industry data where a majority of data submitters agree the substance is a skin sensitiser. The acetylcholinesterase activity was measured in both brain and liver as a biomarker of toxicity. A combination of cytological and leukocyte culture techniques is described which constitutes a convenient, reliable approach for chromosome studies of humans and yields the following advantages: 1.1. The description of the computational procedures and use of the computer program with suitable examples from mosquito control programmes are discussed. The rhizobial isolates grown in pesticide-supplemented medium showed comparatively longer lag phase; and a clear-cut demarcation between other growth phases of the batch cultures was missing. Although much research on organophosphorus compounds was done in the 19th century, the insecticidal activity of these chemicals was not discovered until 1937 (Eto 1974). The renewal was done after every 24 hours. Organ Toxicity: Monocrotophos affects the central nervous system by inhibiting cholinesterase, an enzyme essential for normal nerve impulse transmission. Monocrotophos poisoning symptoms, causes, diagnosis, and treatment information for Monocrotophos poisoning (Chemical poisoning - Monocrotophos) with alternative diagnoses, full-text book chapters, misdiagnosis, research treatments, prevention, and prognosis. Changes were observed in the currentsand peak potentials of the nucleotide voltammograms in the presence of the pesticides, with dependence on the pesticide concentration (from 5.0×10-7 to 5.0×10-5molL-1)and the interaction time (from 1min to 4 h). Human exposure to monocrotophos from handling, application and reentry operations is minimized by the use of approved respirators and other protective clothing. 1, 1A, or 1B. Probit analysis calculations are highly useful in biology and related sciences. The insect cuticle is the first line of defence against insecticides. However, removal of monocrotophos was maximum by the isolate SR G (34.79%) which was closely followed by SR 01 (33.25%) and SR I (26.99%). Regulatory. Nineteen FFAs were recorded between C10:0 and C22:0 in cuticular lipids of untreated adults; whereas 21 and 19 FFAs were recorded in cuticular lipids of treated males and females, respectively. Feeding was stopped during the experimental duration. Acute organophosphate pesticide poisoning is a common medical emergency with high fatality in agricultural communities of Asia.
