Chandler’s Index: This is a measure used in parasitology to estimate the intensity of hookworm infection within a community. It represents the average number of hookworm eggs per gram of faeces, providing a quantitative indication of the prevalence and intensity of the infection.
Other options:
Match List-I with List-II
| List-I (Categories of Zoonoses) | List-II (Type of life cycle of the infecting organism) |
|---|---|
| (A) Direct zoonoses | (I) Transmitted from an infected vertebrate host to a susceptible vertebrate host |
| (B) Meta-zoonoses | (II) Requires more than one vertebrate host species, but no invertebrate host, in order to complete the developmental cycle of the agent |
| (C) Cyclo-zoonoses | (III) Transmitted biologically by invertebrate vectors |
| (D) Sapro-zoonoses | (IV) Have both a vertebrate host and a non-animal developmental site or reservoir |
