Morphology
The phrase is a straightforward composition of 'order' (a taxonomic rank) with the taxon name 'Rickettsiales', so its meaning as a biological order of bacteria is directly derivable from the constituents. Although the term is technical, the pattern 'order + taxon name' is a standard, cross-linguistic naming convention in biology, so a learner who knows both words would understand the MWE.
Etymology
Order Rickettsiales comes from the scientist Howard Ricketts, who studied tiny bacteria often carried by ticks and lice. The part Rickettsiales is from his name and was used for the whole group, so today order Rickettsiales means 'a group of small, often disease-causing bacteria that live inside cells'.
