QTL Mapping and CRISPR/Cas9 Editing to Identify a Drug Resistance Gene in Toxoplasma gondii
Published on: June 22, 2017
Summary
Trimethoprim is now FDA-approved for acute, uncomplicated bacterial urinary tract infections, showing promise against E. coli. However, pregnant women should avoid it, and widespread use could lead to resistance.
Area of Science:
- Pharmacology
- Infectious Diseases
- Urology
Background:
- Urinary tract infections (UTIs) are common bacterial infections.
- Escherichia coli is a primary causative agent of UTIs.
- Limited treatment options exist for uncomplicated UTIs.
Purpose of the Study:
- To evaluate the efficacy of newly FDA-approved trimethoprim for acute symptomatic uncomplicated bacterial UTIs.
- To compare trimethoprim with existing treatments like ampicillin and cephalexin.
- To identify contraindications and potential risks associated with trimethoprim use.
Main Methods:
- Clinical evaluation of trimethoprim's effectiveness.
- Comparative analysis against ampicillin and cephalexin.
- Assessment of safety profile and resistance patterns.
Main Results:
- Trimethoprim demonstrates favorable comparison with ampicillin and cephalexin for E. coli UTIs.
- Trimethoprim is approved exclusively for acute symptomatic uncomplicated bacterial UTIs.
- Trimethoprim is not FDA-approved for recurrent UTIs.
- Concerns exist regarding potential trimethoprim resistance with indiscriminate use.
Conclusions:
- Trimethoprim offers a new therapeutic option for specific UTI cases.
- Careful administration is crucial to prevent antimicrobial resistance.
- Trimethoprim is contraindicated in pregnant women.
- Further research may be needed for recurrent UTI treatment.

01:27Combined Effects of Drugs: Synergism
Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.

01:30Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
01:16Transduction
Among the three main modes of HGT—transformation, conjugation, and transduction—transduction is unique in that it is mediated by bacteriophages, or bacterial viruses.Transduction occurs in two ways. Generalized transduction occurs during the lytic cycle of a bacteriophage infection. In this process, bacteriophages infect bacterial cells, replicate within them, and ultimately cause cell lysis, releasing newly assembled virions. Occasionally, random fragments of the bacterial genome are...
01:21Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
01:15Anthelminthic Agents
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
01:21Antiprotozoal Agents
Leishmaniasis is a widespread parasitic disease caused by several Leishmania species. It affects millions of people each year and remains a major public health problem in endemic regions. First-line treatment relies on pentavalent antimonials, including meglumine antimoniate and sodium stibogluconate. Even so, how these drugs work has not been fully clear, especially their interaction with parasite-specific biochemical pathways. One key target is trypanothione reductase (TR), an enzyme that...
