“…The recognized status of some Acinetobacter spp. as nosocomial agents is, in part, due to the capability to form biofilms Idzenga 2006;Medina 2007;Regalado 2009;Tognim 2004). Although A. baumannii is the most frequently reported (Towner 2009), Acinetobacter species, such as those of the A. calcoaceticus-A.…”

“…baumannii complex, have been reported also as potentially hazardous for human health. Additionally, members of the species A. haemolyticus, A. lwoffii, A. junii, or A. radioresistans, with widespread distribution in the environment, have been referred to as agents of clinical relevance (Dimopoulou 2003;Idzenga 2006;Kappstein 2000;Poirel 2008;Quinteira 2007;Regalado 2009;Tognim 2004). Given the ubiquity of these species, their capability to cross between different water compartments (waste, surface, and ground), and their capacity to infect humans, the presence of Acinetobacter spp.…”

A 42-year-old man, presented to the Medicine Department of our hospital with the complaint of high grade fever, vomiting, yellowish discoloration of sclera, abdominal distension and weakness since last one week. Patient also gave history of pain in abdomen which was usually located in the right hypochondrium and abdominal discomfort since last one month. There was a history of diabetes mellitus type-2 since last two years; he was on antihyperglycaemic medication irregularly. No history of tuberculosis or similar episode in the past and no relevant family history were present. On examination he was conscious, febrile (Temperature-39°C), pulse rate 98/min and blood pressure were 110/88 mmHg. He had pallor and icterus. As per abdominal examination patient had distended abdomen, tenderness in right hypochondrium and epigastrium regions, umbilicus inverted, nodulated vein were seen, itching marks present on lower abdomen and free fluid present, but, abdomen thrill were absent. There was tender hepatomegaly 4cm below the costal margin, but spleen was not palpable. Rest of systemic examination was within normal limit. Laboratory haematological investigation revealed hemoglobin 8.5gm/dl, total leukocytes count 6100/cumm, (polymorphs 74 %, lymphocytes 24%, eosinophil 2 %), Platelets count of 1.5 lacs/cumm, however liver enzymes (SGOT/SGPT-92/65), coagulation profile (PT/PTTK-12.6/27.0) and Alkaline phosphatase were elevated to 958 IU. Renal function and serum electrolytes were within references range.Serology for Hepatitis B surface antigen (HBSAg-7.38 IU/L) was also elevated from the normal reference range. While, serology from HIV and other hepatitis markers (HCV) were non-reactive. Widal test and IgM leptospira were also negative. Ultrasonography of the abdomen showed enlargement of the liver with features suggestive of abscess measuring 8cm×8cm×8.6cm and volume 700CC involving segment VI and VII along with mild ascites. Ultrasound guided liver aspiration was done. About 30ml of pus was aspirated and sent for microbiological investigations, for culture and sensitivity. The pus sample received was processed as per standard microbiological protocol. A wet mount of pus was negative for Trophozoites of Entamoeba histolytica. Ziehl-Nelsen was negative for acid fast bacilli. Direct Gram's stain showed gram negative bacilli along with the pus cells [Table/ Fig-1]. Haemolytic colonies of 2-3mm diameter grew on blood agar and non-lactose fermenting colonies on Mac-Conkey agar. The isolate was identified as A.lwoffii on the basis of biochemical reactions with cytochrome oxidase (negative), oxidative/fermentative glucose (negative), nitrate reduction (negative), and citrate (negative). It was confirmed by automated technique with Vitek-2 system. It was found to be ABSTRACTAcinetobacter lwoffii is a gram negative aerobic non-fermenter bacilli. It is considered as an important emerging pathogen after Acinetobacter baumannii in patients with impaired immune system and in nosocomial infections. Here, we present a case of community ...

“…However, it is clear that other species are also clinically important, with rpoB sequencing having been instrumental in providing a means of species identification facilitating assessment of the prevalence and clinical relevance of some of the less common species (6,8,15,16). Among these, A. lwoffii/genomic species 9 (now considered synonyms for the same species) (10) is relatively commonly found from blood, sometimes as a result of contamination from the skin but also associated with bacteremia (12,13), and a rapid method of detection would be useful. Recently, a carbapenem-hydrolyzing class D ␤-lactamase, OXA-134, has been described in A. lwoffii, providing a potential target for species-specific identification (4).…”

bla OXA-134 genes and variants were sought in 21 species of Acinetobacter and found in A. lwoffii, genomic species 9 (regarded as synonyms), and A. schindleri. Sequencing revealed a 9-bp deletion in the gene in the type strain of genomic species 9 (ATCC 9957) relative to the gene in the type strain of A. lwoffii (ATCC 15309). Primers based on the gene without the deletion gave specific amplification of 29 of 30 clinical isolates of A. lwoffii/genomic species 9.
