Trivia questions: Betalactam, Tetracyclines and cephalexin

Betalactam

β-lactam antibiotics (β-lactams) refer to a large class of antibiotics with a β-lactam ring in the chemical structure. Basically, all antibiotics including β-lactam nucleus in their molecular structure belong to β-lactams Antibiotics, which are the most widely used types of existing antibiotics.

Beta lactam family

Beta lactam family includes penicillin and its derivatives, cephalosporins, monoamide rings, carbapenems and penicillin enzyme inhibitors, as well as newly developed cephamycins, thiomycins, monocyclics β-lactams and other atypical β-lactam antibiotics.

Beta lactamase

Beta-lactamase is a class of enzymes secreted by resistant bacteria against lactam antibiotics. It can be combined with beta-lactam ring to cleave beta-lactam ring and be destroyed, and lose antibacterial activity. It is the main reason for the resistance of these bacteria.

Tetracyclines

Tetracyclines are a class of broad-spectrum antibiotics produced by actinomycetes, including chlortetracycline, oxytetracycline, tetracycline, and the semi-synthetic derivatives metoxycycline The structure of cyclamycin, dimethylaminotetracycline, etc. contains naphthylphenyl skeleton.

How do tetracyclines affect and destroy bacteria?

The mechanism of action is that the drug can specifically bind to the A position of the 30S subunit of the bacterial ribosome, preventing the connection of the aminoacyl-tRNA at this position, thereby inhibiting the growth of the peptide chain and affecting bacterial protein synthesis.

Tetracycline class of antibiotics

Tetracyclic antibiotics are a class of broad-spectrum antibiotics produced by actinomycetes. Because their structures contain a tetraphenyl skeleton, they are called tetracyclic antibiotics.
Common tetracyclic antibiotics are oxytetracycline, chlortetracycline, tetracycline and semi-synthetic derivatives, such as doxycycline. Tetracycline antibiotics are widely used for Chlamydia, Mycoplasma and Rickettsia infections.
It can be used to treat malignant tumors, refractory liquid pneumothorax, axillary odor, various cysts, acne, pemphigus, etc. Its adverse drug reactions mainly include gastrointestinal reactions, liver and kidney function damage, allergic reactions, especially affecting the development of teeth and bones.
Therefore, the use of tetracycline antibiotics is prohibited for children under eight years of age.

Cephalexin

Cefalexin, antibiotics β-lactams cephalosporins. It can inhibit the synthesis of the cell wall, swell the cell contents to rupture and dissolve, and kill bacteria.

Cephalexin mechanism of action

Its mechanism of action is to inhibit the cell wall synthesis of bacterial dividing cells by binding to one or more penicillin-binding proteins (PBPs) (cephalexin mainly binds to PBP-3), thereby playing an antibacterial effect.

Cephalexin uses

Broad-spectrum antibiotics. Mainly used for Gram positive and negative bacterial infections, such as: influenza, hemorrhagic septicemia, streptococcosis, swine erysipelas, anthrax, emphysema, malignant edema, actinomycosis, necrotizing bacillus disease, hook end Septicemic fever (41-43 °C) or persistent low temperature (below 37 °C) caused by spirochete disease, indigestion, drinking cold water, sleeplessness, cripple walking, blue ears, tearing, etc. At the same time, it is used to treat various inflammatory diseases, such as: infectious pleura pneumonia, pneumonia, atrophic rhinitis, blue ear disease, mastitis, hysteritis, stomatitis, urethritis and other cough and wheezing, difficulty breathing, low pregnancy, more stillbirths or death of piglets 7-10 days after birth, breast swelling, milk deterioration, decreased milk production, foot and mouth ulceration, salivation, sores and purulence.

Cephalexin for dogs

Cephalosporins are the most widely used anti-inflammatory drugs in the clinic. They are mainly aimed at Gram-negative and Gram-positive bacteria, and can treat bacterial infections in the respiratory tract, digestive tract, and urinary tract.

Cefalexin side effects

1. Gastrointestinal reactions: nausea, vomiting, diarrhea and abdominal discomfort are more common gastrointestinal symptoms, occasionally pseudomembranous enteritis.
2. Nervous system reaction: A few patients may experience dizziness, diplopia, tinnitus, convulsions and other nervous system reactions.
3. Hepatotoxicity: A few patients may have transient liver dysfunction (temporal elevation of serum alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase) after medication.
4. Nephrotoxicity: A small number of patients may experience temporary increases in urea nitrogen, creatine, and creatinine, and occasional proteinuria and oliguria may occur.
5. Blood system: Occasional drop in hemoglobin, thrombocytopenia, neutropenia, eosinophilia, etc. after medication.
6. Others: Long-term medication may cause bacterial flora imbalance and double infection; vitamin K and vitamin B deficiency may also occur.

Cephalexin toxicity

1. Gastrointestinal reactions are the most common, with an incidence of about 4.5%. There are diarrhea, nausea, vomiting, stomach pain, lack of appetite, constipation, and individual serum transaminases increase. It is rare to have headaches, dizziness, blurred consciousness, and general fatigue.
2. Allergic manifestations include urticaria, maculopapular rash, systemic itching, drug fever, eosinophilia, etc. There are reports of direct Coomb's test positive.
3. Double infection mainly occurs in the perineum, and Candida albicans or other drug-resistant bacteria are common infections.
4. Cefalexin has been reported to cause disulfide reaction in alcohol withdrawal in 2 cases. The patient drank beer after taking medicine for a few days, and suffered from general malaise, chest tightness, shortness of breath, sweating, irritability, etc. ECG showed pre-atrial contraction, after symptomatic treatment restore. Drinking beer again the next day, the above symptoms reappeared. Disulfiram-like reactions caused by drinking liquor are even heavier and even fatal. Various drugs such as cephalosporin antibiotics and dysentery have their response and should be paid attention to clinically.

Cephalexin allergy

Allergic reactions such as rash, urticaria, erythema, and drug fever are more common, and occasionally anaphylactic shock.

Summary

As antibiotics, betalactam, tetracyclines and cephalexin are often used as veterinary drugs to treat poultry diseases and to promote the growth and production of poultry. This has led to the residue of betalactam, tetracyclines or cephalexin in many chicken and eggs.
Betalactam, tetracyclines and cephalexin test for egg is essential, and Ballya has specifically studied this situation and has developed a rapid test kit for sulfonamide. Yes, people in need can quickly and easily detect sulfonamide in eggs. The test results comply with EU standards. Not only the operation is simple, but also the time is short and the precision is high. Ballya will continue to conduct more research in this area.
