The best title is the following:
“Serological Survey of Toxoplasmosis in four rural communities in southern Africa.
When analyzed it does not show how it is going to be conducted (mentioning the word survey is not necessary). The outcome is mentioned “Toxoplasmosis is the diagnosis mentioned. Participants are mentioned as the people living in the rural part of the southern region of Africa.
The title does not show the intervention - what will be done - the comparison is not mentioned -maybe they would compare the 4 rural areas with in southern africa with the 4 rural in the northern maybe but nothing is mentioned.
"We should stop using ampicillin and cotrimoxazole to treat shigellosis." this is a bad title - it is stated as a conclusion and does not show who the participants are and it does not show areas of focus.
"Rapid emergence of in-vitro resistance to ampicillin and cotrimoxazole in Shigella dysenteriae type d from Musanze." This is a bad title because the word Musanze may not be known by many people. The participants are not mentioned as well.
"Risk factors for typhoid in children in remote areas of Vietnam"- This may be considered as a good title too - It shows the intervention, the area, the participants are mentioned and less words: 11 words.
"Report of an investigation into poor hygiene behaviour as a reason for the acquisition of typhoid fever by some ethnic minority children in Vietnam" This is a bad title - it has a lot of unnecessary words, more than 20 words which disqualify the title as well.
