Modern Molecular Taxonomy

56
Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

DNA Microarrays

17.6K
Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...

Single Nucleotide Polymorphisms-SNPs

15.3K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Area of Science:

  • Veterinary Parasitology
  • Molecular Diagnostics
  • Epidemiology

Background:

  • Cryptosporidium felis (C. felis) is an emerging protozoan parasite.
  • Limited data exists on C. felis prevalence in cattle, particularly in Iraq.
  • Understanding its epidemiology is crucial for public health.

Purpose of the Study:

  • To detect C. felis in diarrheic calves in Iraq using molecular methods.
  • To investigate the prevalence and risk factors associated with C. felis infection in cattle.
  • To document local C. felis isolates genetically.

Main Methods:

  • Fecal samples from 130 diarrheic calves in Wasit province, Iraq, were analyzed.
  • DNA extraction followed by polymerase chain reaction (PCR) targeting the HSP70 gene of C. felis.
  • Clinical parameters and demographic data were recorded and analyzed.

Main Results:

  • C. felis was detected in 17.69% of the sampled calves.
  • No significant differences in clinical signs were observed between infected and non-infected calves.
  • Higher prevalence was noted in younger calves (≤6 months) and female calves.

Conclusions:

  • This is the first study to report C. felis in Iraqi cattle using PCR.
  • The findings suggest a wider global distribution of C. felis in cattle than previously known.
  • There is a potential risk of C. felis transmission from cattle to humans.
