+ # BiTTE
14
+
15
+ BiTTE is an application within the CarbConnect platform. It is designed for the simple and efficient classification of microorganisms from Gram-stained microscopy images.
16
+
17
+ The app classifies findings into seven primary groups:
18
+
19
+ 1. Gram-negative rods (GNR)
20
+ 2. Gram-negative cocci (GNC)
21
+ 3. Gram-positive rods (GPR)
22
+ 4. Gram-positive cocci (GPC)
23
+ 5. Yeast-like fungi
24
+ 6. No bacteria
25
+ 7. Multiple bacteria
26
+
27
+ BiTTE also supports more detailed subcategories beyond these primary output groups.
28
+
29
+ ## Intended Uses and Limitations
30
+
31
+ BiTTE is strictly intended for **Research Use Only (RUO)**.
32
+
33
+ It is **not** intended for:
34
+
35
+ - clinical diagnostics
36
+ - medical procedures
37
+ - patient management
38
+ - therapeutic selection
39
+ - any regulated clinical use
40
+
41
+ For further details, please refer to the BiTTE Learn More page on CarbConnect.
42
+
43
+ ## How to Use
44
+
45
+ A video tutorial demonstrating how to use the app is available on YouTube.
46
+
47
+ ## Training Data
48
+
49
+ The model was trained on a dataset of Gram-stained images of urine and blood culture specimens generously provided by:
50
+
51
+ - the School of Medicine, Kobe University
52
+ - the National Center for Global Health and Medicine (NCGM)
53
+
54
+ Specimens were Gram-stained using either the Favor or Barmy method.
55
+
56
+ Image acquisition was performed by photographing specimens through the eyepiece of an optical microscope at **1000x magnification** using a smartphone camera.
57
+
58
+ The dataset captures frequently encountered clinical bacterial species and includes:
59
+
60
+ - 15 species in urine specimens
61
+ - 19 species in aerobic blood culture specimens
62
+ - 13 species in anaerobic blood culture specimens
