The number of &lt;i&gt;pmp&lt;\/i&gt; coding sequences differs between &lt;i&gt;Chlamydia&lt;\/i&gt; species, but it is unknown whether the number of &lt;i&gt;pmp&lt;\/i&gt; coding sequences is constant within a &lt;i&gt;Chlamydia&lt;\/i&gt; species. The level of conservation of the Pmp proteins has previously only been determined for &lt;i&gt;Chlamydia trachomatis.&lt;\/i&gt; As different Pmp proteins might be indispensible for the pathogenesis of different &lt;i&gt;Chlamydia &lt;\/i&gt;species, this study investigated the conservation of Pmp proteins both within and across &lt;i&gt;C. trachomatis,&lt;\/i&gt;&lt;i&gt;C. pneumoniae,&lt;\/i&gt;&lt;i&gt;C. abortus,&lt;\/i&gt; and &lt;i&gt;C. psittaci.&lt;\/i&gt; The &lt;i&gt;pmp&lt;\/i&gt; coding sequences were annotated in 16 &lt;i&gt;C. trachomatis,&lt;\/i&gt; 6 &lt;i&gt;C. pneumoniae,&lt;\/i&gt; 2 &lt;i&gt;C. abortus,&lt;\/i&gt; and 16 &lt;i&gt;C. psittaci&lt;\/i&gt; genomes. The number and organization of polymorphic membrane coding sequences differed within and across the analyzed &lt;i&gt;Chlamydia &lt;\/i&gt;species. The length of coding sequences of &lt;i&gt;pmpA,&lt;\/i&gt;&lt;i&gt;pmpB,&lt;\/i&gt; and &lt;i&gt;pmpH&lt;\/i&gt; was conserved among all analyzed genomes, while the length of &lt;i&gt;pmpE\/F&lt;\/i&gt; and &lt;i&gt;pmpG,&lt;\/i&gt; and remarkably also of the subtype &lt;i&gt;pmpD,&lt;\/i&gt; differed among the analyzed genomes. PmpD, PmpA, PmpH, and PmpA were the most conserved Pmp in &lt;i&gt;C. trachomatis,&lt;\/i&gt;&lt;i&gt;C. pneumoniae,&lt;\/i&gt;&lt;i&gt;C. abortus,&lt;\/i&gt; and &lt;i&gt;C. psittaci&lt;\/i&gt;, respectively.
