Acholeplasma laidlawii are small bacteria which lack a cell wall.[1] Like other Acholeplasma and Mycoplasma, A. laidlawii has been identified as a common contaminant of growth media for cell culture.[2]

History
A. laidlawii was first isolated from sewage in London in 1936 and was named after its discoverer, Patrick Laidlaw.[3]
Genetics
A. laidlawii has a relatively small genome comprising 1.5Mbp. Additionally its genome has a low GC-content of just 31%.[1] The A. laidlawii genome has been sequenced.[1]

- Analysis of the Complete Genomes of Acholeplasma brassicae , A. palmae and A. laidlawii and Their Comparison to the Obligate Parasites from ' Candidatus Phytoplasma'
- Kube M, Siewert C, Migdoll AM, Duduk B, Holz S, Rabus R, Seemüller E, Mitrovic J, Müller I, Büttner C, Reinhardt R.Author information Division Phytomedicine, Department of Crop and Animal Sciences, Humboldt-Universität zu Berlin, Berlin, Germany.AbstractAnalysis of the completely determined genomes of the plant-derived Acholeplasma brassicae strain O502 and A. palmae strain J233 revealed that the circular chromosomes are 1,877,792 and 1,554,229 bp in size, have a G + C content of 36 and 29%, and encode 1,690 and 1,439 proteins, respectively. Comparative analysis of these sequences and previously published genomes of A. laidlawii strain PG-8, 'Candidatus Phytoplasma asteris' strains, 'Ca. P. australiense' and 'Ca. P. mali' show a limited shared basic genetic repertoire. The acholeplasma genomes are characterized by a low number of rearrangements, duplication and integration events. Exceptions are the unusual duplication of rRNA operons in A. brassicae and an independently introduced second gene for a single-stranded binding protein in both genera. In contrast to phytoplasmas, the acholeplasma genomes differ by encoding the cell division protein FtsZ, a wide variety of ABC transporters, the F0F1 ATP synthase, the Rnf-complex, SecG of the Sec-dependent secretion system, a richly equipped repertoire for carbohydrate metabolism, fatty acid, isoprenoid and partial amino acid metabolism. Conserved metabolic proteins encoded in phytoplasma genomes such as the malate dehydrogenase SfcA, several transporters and proteins involved in host-interaction, and virulence-associated effectors were not predicted for the acholeplasmas. © 2013 S.

- Frequency of different human mollicutes species in the mucosa of the oropharynx, conjunctiva, and genitalia of free-ranging and captive capuchin monkeys (Cebus spp.).
- Neto RL, Marques LM, Guimarães AM, Yamaguti M, Oliveira RC, Gaetti-Jardim E Jr, Medina AO, Sanfilippo LF, Timenetsky J.Author information Instituto de Ciências Biomédicas II, Universidade de São Paulo, Rua Professor Lineu Prestes, São Paulo, SP, Brazil.AbstractThis study is the first to evaluate the occurrence of several Mollicutes species in Brazilian capuchin monkeys (Cebus spp.). Mollicutes were detected by culture and polymerase chain reaction (PCR) in samples of the oropharyngeal, conjuctiva, and genital mucosae of 58 monkeys. In the oropharynx, Mollicutes in general (generic PCR to the Class), and those of the genus Ureaplasma (genus PCR), were detected in 72.4% and 43.0% of the samples, respectively. The identified species in this site included: Mycoplasma arginini (43.1%), M. salivarium (41.4%), and M. pneumoniae (19.0%). Both Ureaplasma and Mycoplasma are genera of the order Mycoplasmatales. In the preputial/vaginal mucosa, PCR detected Mollicutes in general in 27.58% of the samples, the genus Ureaplasma in 32.7%, the species M. arginini in 8.6%, and Acholeplasma laidlawii of the order Acholeplasmatales in 1.7% In the conjunctiva, Mollicutes in general were detected in 29.3% of the samples, with 1.7% being identified as A. laidlawii. Culturing was difficult due to contamination, but two isolates were successfully obtained. The Mollicutes species of this study provided new insights into these bacteria in Brazilian Cebus. Studies are lacking of the actual risk of Mollicutes infection or the frequency at which primates serve as permanent or temporary reservoirs for Mollicutes. In the present study, the samples were collected from monkeys without clinical signs of infection. The mere presence of Mollicutes, particularly those also found in humans, nevertheless signals a need for studies to evaluate the impact of these microorganisms on the health of non-human primates (NHPs) and the possibility of cross-species transmission between NHPs and humans.
