A organothiophosphorus cholinesterase inhibitor that is used as an anthelmintic, insecticide, and as a nematocide.
A pesticide or chemical agent that kills mites and ticks. This is a large class that includes carbamates, formamides, organochlorines, organophosphates, etc, that act as antibiotics or growth regulators.
A sweet viscous liquid food, produced in the honey sacs of various bees from nectar collected from flowers. The nectar is ripened into honey by inversion of its sucrose sugar into fructose and glucose. It is somewhat acidic and has mild antiseptic properties, being sometimes used in the treatment of burns and lacerations.
Diseases in persons engaged in cultivating and tilling soil, growing plants, harvesting crops, raising livestock, or otherwise engaged in husbandry and farming. The diseases are not restricted to farmers in the sense of those who perform conventional farm chores: the heading applies also to those engaged in the individual activities named above, as in those only gathering harvest or in those only dusting crops.
I'm sorry for any confusion, but "Iowa" is a state located in the Midwestern United States and does not have a medical definition.
Insect members of the superfamily Apoidea, found almost everywhere, particularly on flowers. About 3500 species occur in North America. They differ from most WASPS in that their young are fed honey and pollen rather than animal food.
Pesticides designed to control insects that are harmful to man. The insects may be directly harmful, as those acting as disease vectors, or indirectly harmful, as destroyers of crops, food products, or textile fabrics.
Chemicals used to destroy pests of any sort. The concept includes fungicides (FUNGICIDES, INDUSTRIAL); INSECTICIDES; RODENTICIDES; etc.

Identification of an opd (organophosphate degradation) gene in an Agrobacterium isolate. (1/12)

We isolated a bacterial strain, Agrobacterium radiobacter P230, which can hydrolyze a wide range of organophosphate (OP) insecticides. A gene encoding a protein involved in OP hydrolysis was cloned from A. radiobacter P230 and sequenced. This gene (called opdA) had sequence similarity to opd, a gene previously shown to encode an OP-hydrolyzing enzyme in Flavobacterium sp. strain ATCC 27551 and Brevundimonas diminuta MG. Insertional mutation of the opdA gene produced a strain lacking the ability to hydrolyze OPs, suggesting that this is the only gene encoding an OP-hydrolyzing enzyme in A. radiobacter P230. The OPH and OpdA proteins, encoded by opd and opdA, respectively, were overexpressed and purified as maltose-binding proteins, and the maltose-binding protein moiety was cleaved and removed. Neither protein was able to hydrolyze the aliphatic OP malathion. The kinetics of the two proteins for diethyl OPs were comparable. For dimethyl OPs, OpdA had a higher k(cat) than OPH. It was also capable of hydrolyzing the dimethyl OPs phosmet and fenthion, which were not hydrolyzed at detectable levels by OPH.  (+info)

Cloning and expression of the phosphotriesterase gene hocA from Pseudomonas monteilii C11. (2/12)

The cloning of a gene encoding the novel phosphotriesterase from Pseudomonas monteilii C11, which enabled it to use the organophosphate (OP) coroxon as its sole phosphorus source, is described. The gene, called hocA (hydrolysis of coroxon) consists of 501 bp and encodes a protein of 19 kDa. This protein had no sequence similarity to any proteins in the SWISS-PROT/GenBank databases. When a spectinomycin-resistance cassette was placed in this gene, phosphotriesterase activity was abolished and P. monteilii C11 could no longer grow with coroxon as the sole phosphorus source. Overexpression and purification of HocA as a maltose-binding protein fusion produced a protein having a broad substrate specificity across oxon and thion OPs. Michaelis-Menten kinetics were observed with the oxon OPs, but not with the thion OPs. End-product inhibition was observed for coroxon-hydrolytic activity. Increased expression of hocA was observed from an integrative hocA-lacZ fusion when cultures were grown in the absence of phosphate, suggesting that it might be part of the Pho regulon, but the phosphate-regulated promoter was not cloned in this study. This is believed to be the first study in which a gene required for an organism to grow with OP pesticides as a phosphorus source has been isolated.  (+info)

Coumaphos is an antiparasitic agent, specifically a type of chemical called an organophosphate. It works by inhibiting the action of certain enzymes in insects and other parasites, which leads to their death. Coumaphos is used as a topical treatment for lice and scabies infestations in humans, and it is also used in veterinary medicine to control internal and external parasites in livestock and pets.

It's important to note that coumaphos is highly toxic and can cause serious health effects if ingested, inhaled, or absorbed through the skin. Therefore, it should be handled with care and used only as directed by a healthcare professional.

Acaricides are a type of pesticide that are specifically used to kill acarines, which are mites and ticks. These agents work by targeting the nervous system of the acarines, leading to paralysis and eventually death. Acaricides are commonly used in agricultural settings to protect crops from mite infestations, and in medical and veterinary settings to control ticks and mites that can transmit diseases to humans and animals. It is important to use acaricides according to the manufacturer's instructions and to take appropriate safety precautions to minimize exposure to non-target organisms, including humans.

I'm sorry for any confusion, but "honey" is not typically considered a medical term. It is a natural sweet substance produced by honeybees from the nectar of flowers. Honey is composed primarily of fructose and glucose, with small amounts of other sugars, water, proteins, amino acids, vitamins, minerals, enzymes, and various organic compounds.

While honey does have some potential health benefits, such as its antimicrobial properties and its use in wound healing, it is not a medical treatment or intervention. If you have any questions about the medicinal uses of honey or its role in health, I would recommend consulting with a healthcare professional.

"Agricultural Workers' Diseases" is a term used to describe a variety of health conditions and illnesses that are associated with agricultural work. These can include both acute and chronic conditions, and can be caused by a range of factors including exposure to chemicals, dusts, allergens, physical injuries, and biological agents such as bacteria and viruses.

Some common examples of Agricultural Workers' Diseases include:

1. Pesticide poisoning: This can occur when agricultural workers are exposed to high levels of pesticides or other chemicals used in farming. Symptoms can range from mild skin irritation to severe neurological damage, depending on the type and amount of chemical exposure.
2. Respiratory diseases: Agricultural workers can be exposed to a variety of dusts and allergens that can cause respiratory problems such as asthma, bronchitis, and farmer's lung. These conditions are often caused by prolonged exposure to moldy hay, grain dust, or other organic materials.
3. Musculoskeletal injuries: Agricultural workers are at risk of developing musculoskeletal injuries due to the physical demands of their job. This can include back pain, repetitive strain injuries, and sprains and strains from lifting heavy objects.
4. Zoonotic diseases: Agricultural workers who come into contact with animals are at risk of contracting zoonotic diseases, which are illnesses that can be transmitted between animals and humans. Examples include Q fever, brucellosis, and leptospirosis.
5. Heat-related illnesses: Agricultural workers who work outside in hot weather are at risk of heat-related illnesses such as heat exhaustion and heat stroke.

Prevention of Agricultural Workers' Diseases involves a combination of engineering controls, personal protective equipment, and training to help workers understand the risks associated with their job and how to minimize exposure to hazards.

I'm not aware of any recognized medical definition for the term "Iowa." Iowa is actually a state located in the Midwestern United States. It is known for its agricultural production, particularly corn and soybeans, and it is home to various cities such as Des Moines, Cedar Rapids, and Davenport. If you have any medical or health-related question, I would be happy to help with that instead.

"Bees" are not a medical term, as they refer to various flying insects belonging to the Apidae family in the Apoidea superfamily. They are known for their role in pollination and honey production. If you're looking for medical definitions or information, please provide relevant terms.

Insecticides are substances or mixtures of substances intended for preventing, destroying, or mitigating any pest, including insects, arachnids, or other related pests. They can be chemical or biological agents that disrupt the growth, development, or behavior of these organisms, leading to their death or incapacitation. Insecticides are widely used in agriculture, public health, and residential settings for pest control. However, they must be used with caution due to potential risks to non-target organisms and the environment.

Pesticides are substances or mixtures of substances intended for preventing, destroying, or repelling pests. Pests can be insects, rodents, fungi, weeds, or other organisms that can cause damage to crops, animals, or humans and their living conditions. The term "pesticide" includes all of the following: insecticides, herbicides, fungicides, rodenticides, bactericides, and various other substances used to control pests.

It is important to note that while pesticides are designed to be toxic to the target pests, they can also pose risks to non-target organisms, including humans, if not used properly. Therefore, it is essential to follow all label instructions and safety precautions when handling and applying pesticides.

Beyond Pesticides, August 12, 2009) A new study examining the effects of the mosquito repellent DEET on insects, mice and human proteins reports that the chemical interferes with a prominent central nervous system enzyme. This effect is magnified when exposure to DEET is combined with exposure to certain other pesticides.. Entitled, "Evidence for inhibition of cholinesterases in insect and mammalian nervous systems by the insect repellent deet," and published in BioMed Central (BMC) Biology, the study utilized toxicological, biochemical and electrophysiological techniques to show that DEET is not simply a behavior-modifying chemical, but that it also inhibits cholinesterase activity in both insect and mammalian neuronal preparations. The researchers examined DEETs effects on mosquitoes, cockroach nerves, mouse muscles, and enzymes purified from fruit flies and humans. Applications of DEET slowed or halted the actions of the enzyme acetylcholinesterase. This enzyme is crucial for regulating ...
