To answer the question "Which of the following pathogens can pass from mother to infant during childbirth?", we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Pathogens**:
- The question lists several pathogens: Chlamydia, Neisseria, and Trypanosoma.

2. **Examine Chlamydia**:
- Chlamydia is caused by the bacterium *Chlamydia trachomatis*. It is a sexually transmitted disease (STD).
- If a mother is infected with Chlamydia during childbirth, the pathogen can be transmitted to the infant.

3. **Examine Neisseria**:
- Neisseria refers to the bacterium *Neisseria gonorrhoeae*, which causes gonorrhea, another STD.
- Similar to Chlamydia, if a mother has gonorrhea, the infection can be passed to the infant during childbirth.

4. **Examine Trypanosoma**:
- Trypanosoma is a type of protozoan, and one of the diseases it causes is sleeping sickness.
- If the mother is infected with Trypanosoma, it can also be transmitted to the infant during childbirth.

5. **Conclusion**:
- All the pathogens mentioned (Chlamydia, Neisseria, and Trypanosoma) can be transmitted from mother to infant during childbirth.
- Therefore, the correct answer is **option 4: all of these**.
