Mycoplasmas were isolated from multiple tissues of diseased American alligators (Alligator mississippiensis). This paper presents biochemical, serological and molecular genetic characterizations of a lethal pathogen of alligators for which the name Mycoplasma alligatoris sp. nov. is proposed. The type strain is A21JP2T (ATCC 700619T).

Sialidase and N-acetylneuraminate catabolism in nutrition of Mycoplasma alligatoris.

The contribution of N-acetylneuraminate scavenging to the nutrition of Mycoplasma alligatoris was examined. The wild-type grew substantially faster (P<0.01) than the mutant strains that were unable either to liberate (extracellular NanI mutants) or to catabolize (NanA mutants) N-acetylneuraminate from glycoconjugates in minimal SP-4 medium supplemented only with serum, but the growth of sialidase-negative mutants could not be restored to wild-type rate simply by adding unconjugated sialic acid to the culture medium.

Article Synopsis
- Mycoplasma alligatoris and Mycoplasma crocodyli are closely related species, with M. alligatoris being highly virulent and M. crocodyli being less harmful.
- Research involved comparing their genomes to uncover the reasons behind M. alligatoris' high virulence in a group of generally less harmful microorganisms.
- Key differences were found in M. alligatoris, particularly in its genes related to sialidases and the N-acetylneuraminate scavenging and catabolism pathway.

Through a survey of the phylogenetic distribution of sialidase among mycoplasmas, we detected activity secreted by the type strains of 3 of 11 species frequently or first isolated from dogs. The specific activity of washed cells of the type strains of Mycoplasma canis, Mycoplasma cynos, and Mycoplasma molare ranged from 5.2+/-0.

Mycoplasma alligatoris causes acute lethal infection of alligators (Alligator mississippiensis). The objective of this study was to assess the current seroprevalence of M. alligatoris among free-ranging, juvenile and subadult alligators in Florida.

Article Synopsis
- Mycoplasma iguanae, a new species, was isolated from vertebral abscesses in two feral iguanas from Florida and evaluated for antibiotic sensitivity.
- The strain showed less sensitivity to antibiotics like chloramphenicol and erythromycin, with effectiveness noted for clindamycin and enrofloxacin at low concentrations.
- Enrofloxacin may be a viable treatment option for mycoplasmosis in iguanas, although its effectiveness in vertebral tissues could be limited compared to plasma levels.
