The only gram negative cocci are Neisseria spp.

I have never come across
Hemophilus vaginalis as G negative cocci! Do you have any reference? That would be useful.

it is for sure > hemophilis vaginalis
this thin fishy odor smell discharge and it should be greyish or off white colour all are indicating toward gardnerella vaginalis which is once classified as hemophilis vaginalis
and these epithelial cells that covered with the bacteria should be clue cells

G vaginalis originally, it was known as Haemophilus vaginalis and then as Corynebacterium vaginale.

Agreed, G.vaginalis is a gram variable rod and not a coccus

More specifically speaking, Heamophilus is coccobacillus, so can exist in both coccoid & bacilli shapes.

Secondly, the scenario is about bacterial vaginosis (fishy odor & clue cells), Gardnerella vaginalis was previously classified as Heamophilus Vaginalis & Corynebacterium vaginalis.

G.Vaginalis was previously k/a H.vaginalis.Gardnerella is a different genus from heemophilus now and G.vaginalis is the only species in it which is a rod and not a cocci.

Gardnerella vaginalis is a facultatively anaerobic Gram-variable rod that can cause bacterial vaginosis in some women as a result of a disruption in the normal vaginal microflora.
